Second, the analysis of trends occur.
According to the Guangzhou international professional weather forecast, Guangzhou May rainfall slightly less 1 to 2 percent, or slightly less normal June 1 to 2 percent in the late late April, mid-May Early, late and early June in mid-late June there will be four major precipitation process.

Third, control advice.
1, the timely removal of pests leaves and debris, and concentrated buried or burned. Well Fitness cultivation, improve plant disease and insect resistance ability.

2. Timely chemical control requires the use of high efficiency, low toxicity and safe agents for prevention and treatment, the rain if the spraying, spraying should promptly fill in the rain.

Rice Drought Resistance Gene

Drought stress is a major limiting factor for crop production. Cuticular wax plays an important role in preventing water loss from drought stress. However, the genetic control of cuticular wax deposition under drought stress conditions has not been characterized. 

Here, we identified a rice gene Drought-Induced Wax Accumulation 1 (DWA1) encoding a very large protein (2,391 aa in length) containing multiple enzymatic structures, including an oxidoreductase-like domain; 

a prokaryotic nonribosomal peptide synthetase-like module, including an AMP-binding domain; and an allene oxide synthase-like domain. This previously unreported putative megaenzyme is conserved in vascular plants. A dwa1 KO mutant was highly sensitive to drought stress relative to the WT. DWA1 was preferentially expressed in vascular tissues and epidermal layers and strongly induced by drought stress. 

The dwa1 mutant was impaired in cuticular wax accumulation under drought stress, which significantly altered the cuticular wax composition of the plant, resulting in increased drought sensitivity. The mutant had reduced levels of very-long-chain fatty acids, and plants overexpressing DWA1 showed elevated levels of very-long-chain fatty acids relative to the WT. 

The expression of many wax-related genes was significantly suppressed in dwa1 under drought conditions. The AMP-binding domain exhibited in vitro enzymatic activity in activating long-chain fatty acids to form acyl-CoA. Our results suggest that DWA1 controls drought resistance by regulating drought-induced cuticular wax deposition in rice. This finding may have significant implications for improving the drought resistance of crop varieties.

How to prevent potato blackleg disease

Potato blackleg disease is very serious for potato disease,all the grouth period can occure,mainly harm stem base and tubers,make a big damage in the field and cause rotting tubers.This kind of disease is characteristic of early onset, rapid onset, high mortality. It’s very diffulcut to preventent.For damage symptoms of potato blackleg disease occurrence, proposed control measures.

From the onset of symptoms of the disease to the late seedling growth may be the disease, mainly against plant stem base and tubers. Occurrence of the disease is caused by bacteria,Spread through contaminated seed but the soil are generally not contaminated.Contaminated seed and the field is not completely rotten potato primary infection source of disease, with a knife seed is the main way to expand the spread of disease.

Occurrence of disease onset condition is closely related to the degree of temperature and humidity.At higher temperatures the incidence of weight, high temperature and humidity, is conducive to bacterial growth and harm.

Heavy clay soils and poorly drained soils favorable for onset, heavy clay soils often low soil temperature, plant growth is slow, is not conducive to the formation of cork host tissue, reduces the ability of the anti-intrusion; heavy clay soil moisture, is conducive bacteria, spread and invasion, thus heavy clay soil, the incid

Potato environmental requirements

1 potato prefer to like light, because the potato is very like the light, so, it should have the moderate sunshine. it's fear the low light.the length of sunlight should be moderate, about 12 hours. the following condition are very good for potato.Seedling short day, light and proper temperature, tuber long day, light and proper temperature, tuber growth and accumulation of starch shorter day, light, proper temperature and larger temperature difference between day and night.

2.like cold weather,can not endure high temperature during growth in daily average temperature 17 ~ 21 ℃ is appropriate.germinationTemperature should be12 ~ 18 ℃, it's very suitable.Leaf growth requires a higher temperature to 20 ℃ is the most appropriate; Tuber expansion requires a lower temperature, the optimum soil temperature is 16 ~ 18 ℃.

3.like the dry climate, fear of wet weather potato Relative Humidity of 70% to 80% better.

4.Hi moist soil, dry afraid, afraid stains fat trees of soil moisture should be maintained at 70% to 80% maximum water holding capacity of the soil; later made to properly control the water supply of trees, soil moisture should be reduced to 60% to 80%; soil moisture tuber period should be increased to 80% to 85%.

5.Requirements to topsoil deep soil, loose structure, good ventilation and drainage soil rich in organic matter is the most suitable, in particular large porosity, aeration sandy loam cultivated potato, quick emergence, early tuber formation, tuber tidy , potato skin smooth, both high yield and starch content.

6. potato nutritional needs throughout the growing season to absorb most of potash, nitrogen, followed by phosphate least. Each producing about 1,000 kg of tubers absorb nitrogen from 5 to 6 kilograms of pure phosphorus from 1 to 3 kilograms of pure potassium 12 to 13 kg

How to integrated utilization crop straw

There are mainly 5 kinds of ways to integrated utilization crop straw. 

1.As an agricultural fertilizer;

2.As the feed;

3.As a new rural energy;

4.As industrial raw materials;

5.As a basic material.

As fertilizer,Maize straw can complement and balance of soil nutrients,improve soil effectively.It is one of the basic measures of high yield field

construction.The average per acre yield increase of more than 10%.The biggest problem is that it is difficult to straw plowed into the soil.Even if the straw is successfully plough into the soil.In the ditch plow straw shares forming process may also cause problems,it can't decomposition with enough speed,In addition, the straw in the furrows of the shares will also hinder the growth of crop root to deep soil.

As the feed,the corn straw is rich in cellulose, lignin and hemicellulose non starch macromolecule material.As roughage nutritional value is low, must carry on the processing.Processing method have physical method, chemical method and microbial fermentation.

The straw that through physical method and chemical method processing, its palatability and nutritional value are greatly improved.

Rice Mill Machine

Farmers prefer to use the rice mill machine maintain the rice complete and white. However, some rice mill grind rice broken out more, and it's not white. the reason except to the quality of rice.also caused by Milling machine inlet and outlet valves and meters are control is not very well.and the operater can not master it.In order to improve the quality of rice milling, rice milling technology should do some adjustment at the rice mill working.

First, adjust the knife,

ainly to adjust the gap between the meter and the roller cutter, small if the gap is large, the rice milling chamber pressure, meter by the friction force is weak, and therefore can not be unpolished rice, grind the rice is not white in the drum, but the meter rate than high.

Second.Adjust the inlet ant outlet.When importing knife to open a large, export knife off smaller, increase grain rice milling chamber, the pressure increases, the grind out of the beige white, but more broken rice;

1.meter knife and roller gap should be moderate.The gap can not be less than the transverse diameter of the grain, otherwise easily broken rice;A gap of no more than longitudinal diameter of a grain of rice, otherwise rough rice.

2.Import and export knife to fit well. Opening of the general import knife can be controlled throughout the opening degree of 1/2, no more than 2/3.

Progress in Research and Development on Hybrid Rice: A Super-domesticate in China

 Background: China has been successful in breeding hybrid rice strains, but is now facing challenges to develop new hybrids with high-yielding potential, better grain quality, and tolerance to biotic and abiotic stresses. This paper reviews the most significant advances in hybrid rice breeding in China, and presents a recent study on fine-mapping quantitative trait loci (QTLs) for yield traits. 

Scope: By exploiting new types of male sterility, hybrid rice production in China has become more diversified. The use of inter-subspecies crosses has made an additional contribution to broadening the genetic diversity of hybrid rice and played an important role in the breeding of super rice hybrids in China. With the development and application of indica-inclined and japonica-inclined parental lines, new rice hybrids with super high-yielding potential have been developed and are being grown on a large scale. 

DNA markers for subspecies differentiation have been identified and applied, and marker-assisted selection performed for the development of restorer lines carrying disease resistance genes. The genetic basis of heterosis in highly heterotic hybrids has been studied, but data from these studies are insufficient to draw sound conclusions. In a QTL study using stepwise residual heterozygous lines, two linked intervals harbouring QTLs for yield traits were resolved, one of which was delimited to a 125-kb region. 

Conclusions: Advances in rice genomic research have shed new light on the genetic study and germplasm utilization in rice. Molecular marker-assisted selection is a powerful tool to increase breeding efficiency, but much work remains to be done before this technique can be extended from major genes to QTLs.

Tips of Rice Fertilization

Scientific fertilization is very important for improve rice production and efficiency.but in practice,Because we can not master the fertilization techniques, often make rice stricken fertilizer damage.Its performance at stop the growth of seedlings of stagflation.when rice filed have fertilizer damage. causing production lighting, heavy plowing replant the seedlings.

In order To take full advantage of Fertilization on Rice. Except to used fertilizer.must be applied "three fat"that is That tillering,panicle,and particle

Learn the rules and characteristics of rice need fertilizer, we should be carried out in phases and reasonable.。

First,the early tillering Tillering requirements topdressing earlier,50-60% of general tillering fertilizer accounts for the total.Tillering must be used in 7-10 days after transplanting rice, 5-7 kg of urea per acre application.

Second, skillfully panicle. Application time around rods of rice. Mushi 3-4 kg of urea, and with a small amount of phosphorus and potassium applied per acre foliar application of 0.2-0.3% potassium dihydrogen phosphate solution. 50 kg.

Third, particle. To select a sunny afternoon spraying 1% urea solution, or 1: 500 times Huimanfeng active liquid fertilizer, 50 kg per acre.

The five taboos of maize seed storage

The stand or fall of maize seed storage,had a great influence on production.If stored properly, it will cause great losses to production.So what should be paid attention to in the process of storage?

1.Taboo seed moisture content is too high.
 Corn seed moisture content is too high,Once frozen, the embryo will be destroyed,so that its life force and the germination rate declined.So, we should find a way to put the corn seed water content below 15%, which meet the following security level.

2.Taboo seed studs are not enough
  If you doped with unfilled grains, broken grains and dust and other impurities,it can make mixed bacteria and grain storage pest damage to corn.So stored corn seed must be carefully screened to remove impurities, to ensure clarity.

3.Taboo seed moisture
 Because corn seeds organization is osteoporosis, embryo, it is easy to swell, mouldy or even happen.In order to avoid the evil, must place the corn in dry and stable temperature place.

4.Taboo seeds contaminated
 Forbidden to put corn together with chemical fertilizers, pesticides and others, in order to prevent the evil because of pollution.

5.Taboo mice 
 Rat increasingly rampant in recent years, therefore must find ways to eliminate the rats, in order to avoid the has caused a serious loss to the production.

In addition, still should regularly check the seeds in pile, such as temperature, humidity and seed germination rate, once found the problem, and timely solve, avoid due to improper storage of corn, corn production caused irreparable damage.

Corn Pest Control Measures

In agricultural production, field manager have three errors:

One is technical guidance unfulfillment,not timely forecast,can not grasp the favorable opportunity, following administration obvious phenomenon,Sooner or later, can not reach the control effect.

Second,the masses has not strong prevention of mass consciousness.Coupled with household farming, it is difficult to achieve a unified treatment, unified prevention.

Third,use this kind of medicament is a wrong way.Or use a single species in recent years, reducing the control effect,Some farmers in order to improve the control effect, actually use highly toxic pesticides, increasing agricultural pesticide residues. the following is  the preventive measures.

The corn leaf spot.

Prevention indicators are diseased leaves rate bring all the sick leaves out and destroy it. Second, we must strengthen fertilizing watering,of 15%. Manual control can be removed the lower part of diseased leaves,Enhance plant premunition: the third can be used 50% carbendazim WP 500 times, or 5% tuzet WP 500 times spraying, seven days once, twice.

Rice Reaper For Rice Crops

Rice Reaper For Rice Crops

Corn harvester buy five considerations

First, consider the applicability region

Most of China's corn combine harvester are requested row harvest, and corn planting spacing around the country has vastly different existing regional adaptability of corn harvester restricted,Existing corn harvester regional adaptability are subject.Therefore, no row corn harvester should be preferred model users.

Second, consider the return on investment issues

China's current corn harvester can be divided into self-propelled, towed and knapsack three major types.Self-propelled models huge, expensive, long payback period;Trailed models machine leader, reaching 13 to 15 meters, not suited to small plots.Backpack corn harvest can use existing tractor, a relatively small investment, operation efficiency is not high, job mobility and operability are better, it should be the preferred model.

Third, consider matching of power

Currently tractor general power corn harvester in more than 50 horsepower.Farmers in the choice of corn harvester must choose their own power to match the existing tractor models.

http://www.rl-machine.com/products/corn-harvester.html

Fourth, consider the product quality and service problems,finish product.

Fifth, consider straw treatment

Existing corn combine harvester machine is equipped with a straw chopper machine, namely during the snapping job while corn stalks after crushing will throw in the ground, to achieve straw.

Corn seed processing

Corn seed treatment before sowing, the germination rate can be improved,Promote seedling growth,Seed can kill bacteria on the skin, reduce pest damage, can promote all seedlings, seedling, strong. The method of seed treatment are:

1, drying: the selected seeds spread on land or gallery,5-6 cm thick, continuous sun for 2-3 days,Avoid direct spread the seeds on the cement or metal plate, so as to avoid high temperature burn seeds.

2, Pharmacy stirring seed.Prevention and treatment of viral diseases of corn available for 1.5% Zhibingling Ⅱ 100 ml, against an appropriate amount can be mixed with water of 50 kg of maize seed.Prevention of root rot, smut available 50% or 25% Carbendazim Triadimefon WP 100-150 grams, dressing 50 kg;Control soil pests can be 50% phoxim EC 100, watered amount, mixed with 100 kg of maize seed, mix dry can be planted.For soil pests and corn mixed occurrence of disease, it can be mixed Yaojibanzhong, when dressing, first mix pesticides, dried and then mixed with fungicides.

3, special seed coating. An amount of 50 ml, 5-7 kg packet of seeds, both disease prevention and pest control.

Method of Corn Storage

The key to safe storage of corn is to improve the quality of storage,Lower grain moisture.Since around the temperature, air humidity are quite different, it should be based on local circumstances, with the corresponding storage measures.

Grading: Different points of moisture warehousing.When corn warehousing to do according to different water content, according to a different level of separate storage.Lay the initial foundation for the safe storage.high moisture corn should be drying before storage.

Low temperature and seal:According to the corn storage characteristics of application for low temperature and dry storage.It’s have two kinds of methods.One is drying closed, one is frozen closed.

Corn ear Storage:No threshing corn, ear storage is a relatively mature experience. It has long been widely used in Chinese Farmers,Ventilation conditions are good, and encounter cold seasons, hign moisture corn have large breathe, Maintain A balance of heat energy metabolism,Small pile of temperature change.ong-term ventilation In the winter season, to gradually dried corn. When the water dropped to 14.5% ~ 15%, to threshing grain into hiding.
