Soybean sowing seed processing method

1. Selecting Seeds Selecting seeds before soybeans sowing can improve the sowing quality of the beans. The evenly-sorted seeds that have been selected have better fertility than the seeds that were not cleared, and they have high seedlings in the field and are neat and tidy. In particular, when sowing on a soybean seeding machine, soy seeds must be rigorously selected so that one seed can be seeded and one seedling can be preserved.
Seed cleaning and processing has gradually become a new industry, which includes pre-cleaning, selection and classification of bean seeds, drug treatment (seed coating), and packaging and transportation. Seed cleaning and processing is the direction of specialized seed production, commercialization of supply, mechanization of processing and standardization of quality. To do a good job of seed cleaning can reduce the seeding rate, improve the quality of seeds, and facilitate the mechanization of sowing operations, which has a great effect on increasing production.
2. Rhizobia Inoculation Rhizobium inoculation is usually done in the following three ways:
(1) Soil inoculation method Take surface soil from a high-yield, high-yielding soybean field and mix it with soybean seeds. Mix 1 kg of raw soil for every 10 kg of seeds. The soil inoculation method is not as effective as the rhizobia inoculation because the rhizobia are produced by the most effective strains isolated and cultured, and naturally much stronger than the naturally occurring rhizobia.
(2) Rhizobium Inoculation Rhizobium agent is a factory-produced bacterial fertilizer, which is marked on the package with the expiration date and instructions for use. The use of soybean rhizobial agents is simple and does not pollute the environment. Rhizobia agent 3.75 kilograms per hectare was used for seed dressing, with a net income of 150 yuan, with an input-output ratio of 1:20. Assays have shown that rhizobia inoculation can increase 15 kg of pure nitrogen per hectare than non-inoculated soil, which is equivalent to 75 kg of standardized ammonium sulfate. Store it in a cool place before use. Do not expose it to sunlight to prevent Rhizobium being killed by sunlight. The inoculation method is to dilute the fungus in clean water of 20% of the seed weight, and sprinkle it on the surface of the seed, and stir it enough to make the rhizobia stick to all the seed surfaces. The seeds were sowed in wet soil as soon as possible (within 24 hours).
(3) Treatment of soil with inoculum The rhizobia were cultured in a broth medium and made into a granular inoculum, which can be directly used for soil inoculation. This method is costly and should not be used when seed vaccination is not appropriate.
The development of soybean rhizobia is closely related to the environment. Rhizobium life adapts to a certain range of soil acidity. When the soil pH value is lower than 4.6 or higher than 8, the inoculation effect is not obvious; the high temperature and dryness of soil also affect the development of root nodules. Appropriate application of P and K fertilizers can promote the activity of Rhizobium. When there is a large amount of chemical nitrogen fertilizer in the root nodule growth zone of the soil, the formation of root nodules is inhibited.
3, seed disinfection In order to control soybean root rot, use 50% carbendazim seed dressing, the dosage is 0.3% of the seed weight; or use Doufu Mixer seed dressing (carbendazim and thiram is 1:1), can Significantly reduce the incidence of root rot. Seed disinfection can also be carried out with Euclone EC.
4, seed coating
(1) The role of seed coating First, it can effectively control soybean seedling disease and pests, such as the first generation of soybean cyst nematode, root rot, root Liriomyza, aphids, two leaf A and so on. Therefore, it can alleviate the weight of soybeans and meet production cuts. Second, promote the growth of soybean seedlings. In particular, heavy and welcoming soybean seedlings, due to the lack of trace element nutrition caused by the slow growth of seedlings, the leaves are small, after coating with seed coating agent, can supply some trace fertilizers in a timely manner, especially containing some exogenous hormones, can promote seedling growth, Seedling oil green is not yellow. Third, the effect of increasing production is significant. Soybean seed coating improves seedling maintenance, reduces pests and diseases at seedling stage, and promotes seedling growth, thus significantly increasing yield. If Suihua City tests in Xingfu Township, it will increase its production by 18.4% to 24.9%.
(2) Seed coating method The seed distribution department generally uses a seed coating machine to uniformly coat and supply coated seeds. If you can not buy coated seeds, farmers can also buy seed coating agent for artificial coating. The method is to use a plastic bag filled with fertilizer, 20 kg of soybean seeds, while adding 300-350 ml of soybean seed coating agent, roll the bag after a good mouth roll, so that each seed is coated with a seed coating agent, bagging spare.
(3) Precautions for use of seed coating agents First, the selection of seed coating agents should pay attention to the presence or absence of deposits and agglomeration. After coating, the seed surface is smooth and easy to flow. Secondly, the correct use of the drug and the large amount of drug use not only waste medicine, but also produce phytotoxicity. The use of a small amount of drugs reduces the effect. Generally, the use amount (proportion of drug species) in accordance with the manufacturer's instructions is required; thirdly, the seed treated with the seed coating agent is not allowed to be seeded with another drug; fourth, the seed coating agent contains highly toxic pesticides, and attention is paid to preventing pesticide poisoning (including Poultry), take care not to come in direct contact with the skin. If dizziness and nausea occur, you should immediately stay away from the scene. Serious cases should be sent to the hospital immediately.
5, rare earth seeding rare earth is a trace element fertilizer, it is similar by the nature of the wolfberry, wolfberry, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, oyster, etc. 15 The elements consist of lanthanides, plus 17 elements of yttrium and yttrium that are very close to their properties, collectively referred to as rare earth elements. The application of rare earths in agriculture can not only supply trace elements in crops, but also promote the development of crop roots, increase the absorption of nitrogen, phosphorus and potassium by crops, increase the utilization of light energy, and increase production. With rare earth mixed with soybeans, it can promote the growth of soybean roots and increase the photosynthetic rate with an average yield increase of 8.1%. The method of seed dressing is simple and easy. The method is to use 25 grams of rare earth to add 250 grams of water and mix 15 kg of soybean seeds.
In addition, the use of rare earth to spray the foliage at the seedling stage for top dressing also has a good effect. Rare earth can be mixed with a variety of chemical herbicides, fungicides and insecticides without antagonism. China's rare earth resources are abundant, easy to obtain, and have broad application prospects in agriculture.
6. Fertilizer seed dressing Soil proven to be deficient in micronutrients by soil testing, or a comparative test to verify the effect of applying micronutrient fertilizer on the soil, can be seeded with micronutrients before soybean sowing. The dosage is as follows:
Ammonium molybdate uses 5 grams per kilogram of bean seed, and the amount of liquid used for seed dressing is 0.5% of the seed amount. Ammonium molybdate was ground first, placed in a container with a small amount of heat to dissolve water, and the corresponding water was added. Sprayed on the soybean seeds with a sprayer and dried after sowing. Borax, with 0.4 g per kilogram of bean, first dissolves borax in 16 ml of hot water and mixes it evenly with the seeds. Zinc sulphate, with 4-6 grams per kilogram of beans, liquid seed dressing weight 0.5% of the seed weight.
