Wheat seed dressing, you need to understand these things

Seed treatment measures such as seed selection, sun-dried seeding and seed coating are the most important tasks before wheat planting. Many farmers will plant wheat, but what should be noted about wheat seed dressing? What are the misunderstandings? There are a lot of stresses in this. Today we are going to talk about wheat seed dressing.

 

Do these three steps well

 

Seed selection: The seeds of the seeding are screened again, and the seeds of the worms, the mites, the granules, the granules and the grass seeds are removed, especially the grass seeds and the degraded seeds of the grass weeds (commonly known as wild wheat). In this way, the wheat grown in the future will not only be robust and tidy, but also reduce the trouble and cost of selecting and spraying the herbicide. The method of seed selection is very simple. If the seeds are small, it will be a little bit harder. You can use it with sputum. There are many seeds. In recent years, many local agricultural retail stores are equipped with seed selection machines and free services. This measure is relatively simple, but it is necessary and should not be ignored.

 

Sun-breeding: It takes a while for the germination and emergence of wheat seeds sown into the soil, usually about 5 days. Try to achieve rapid emergence in production. Rapid emergence not only consumes less nutrients stored in the seeds, but also facilitates the emergence of three-leaf leaves after emergence, and relies on photosynthesis to produce organic nutrition to support themselves, and the seedlings are more robust. At the same time, the buds that have just emerged from the seeds quickly pass through the soil layer where various germs are active, which actually reduces the risk of being attacked, and the incidence of smut and sheath blight is reduced. In order to quickly sprout seedlings, it is necessary to quickly break the dormancy of the seeds and quickly wake up from the "sleeping dreams". It is a simple measure to quickly break the dormancy of seeds by picking a good weather a few days before sowing.

 

Seed dressing: The so-called seed dressing is to first use a small amount of water to open the medicine and then mix it with the seeds to make the agent evenly adhere to the surface of the seed. The seed dressing can eliminate or reduce the pathogens, pests, etc. in the soil on or around the seed, and has a systemic fungicide and insecticide, which is more suitable for seed dressing. Seed dressing with micro-fertilizer or conditioner can promote the rapid germination and seedling growth of wheat seeds.

 

Selecting a drug should be targeted

 

In recent years, three-in-one seed treatment agents for bactericidal and insecticidal growth and growth have been more popular among farmers. However, the seed dressing is not a panacea. There are technical requirements for what kind of chemicals to mix, the quality of the seed dressing, the seed dressing method, and so on.

 

The purpose of seed dressing should be clear. Seed dressing is only effective for soil-borne or seed-borne diseases, underground pests and some above-ground pests. Seed dressing with micro-fertilizer or conditioner is a supplement to soil fertilization and cannot replace fertilization. For wheat, seed dressing is effective against smut, smut, sheath blight, root rot, total eclipse, clump dwarf, etc., cockroaches, cockroaches, golden worms, locusts, locusts, etc. Rust, powdery mildew, scab, tigers, and wheat bees are ineffective or ineffective.

 

The choice of seed dressing should be targeted. The active ingredients in the seed dressing agent, whether it is a fungicide or an insecticide, have a limited target, and are often only effective for certain diseases or insects, and are ineffective or ineffective for other pests and diseases. Seed dressing agents should be targeted so choose, all disease serious, he would select silthiofam, difenoconazole + fludioxonil yl other ingredients, root rot and severe categories smut benzene ring yl ether It is possible to prevent and control wheat bran and choose imidacloprid or thiamethoxam.

 

It is worth noting that the ingredients in the seed dressing are not as good as possible, and it is the basis for selecting the appropriate active ingredients in a targeted manner. There are too many types of ingredients, and the chemical reactions between them are more complicated, which has the risk of affecting emergence. Therefore, the ingredients of the seed dressing are not good enough, just enough.

 

Early seed dressing is more scientific

 

Selecting the production process and good quality seed dressing: The dosage forms suitable for seed dressing include wettable powder, suspoemulsion, dry seed dressing, suspension seed coating and the like. Try to choose the last two dosage forms with film-forming coating function. Different brands of the same dosage form of the product often have obvious differences in quality. When choosing, you don't have to be superstitious about high-priced, newly-listed exotic products. It is best to choose products that have a history of use and good reputation.

 

It is scientific in advance seed dressing: the principle of seed dressing is to put a layer of medicinal clothes that are only permeable to water and not leaking. This layer of medicinal clothes is stable, and it is related to the action time of the agent on the seeds. Will make the agent better adhere to the seed for a longer period of time. Therefore, it is necessary to dress the seeds in advance, at least three days in advance.

 

It is best to use a special machine to dress and coat, pay attention to controlling the ratio of medicine, seed and water: making the agent form a uniform and firm film on the surface of the seed is the basic requirement for seed dressing. Therefore, it is best to use a special seed coating machine that is highly functional. It is best to do a ratio test of medicine, seed and water before seed dressing, and find the best ratio before operating. After mixing, first dry the sun for a while and then put the seeds into a bag with better permeability and put them in a dry and ventilated place.

 

In short, seed selection, sun-breeding, and seed dressing are not very complicated preparations for sowing, but they are very important for the growth of wheat. When you are careful, you will have better results. (Zhao Zhanzhou)
