With the increase of yield, the effect of sowing techniques on production has gradually increased. Seeding techniques include selection of seed treatment, soil preparation, reasonable density, sowing method, seeding rate and sowing depth.
Seed treatment: drying. Through the sun through the corn seed, after sowing, fast water absorption, early germination, emergence and neat, high emergence rate, seedlings thick.
Soaking and seed dressing: Soaking in fresh water is mainly to supply water and promote germination. The soaking of chemical agents mainly includes potassium dihydrogen phosphate and trace elements. However, if the soaking concentration is too high or the soaking time is too long, the seeds will be easily poisoned and the germination rate will be reduced. The use of Pesticide seed dressing can prevent pests and diseases.
Seed coating is to coat seeds with a layer of medicament. After being sown, the coated seeds have the ability to resist disease, resist insects, and promote rooting and germination. They must be symptomatic for local pests and diseases.
Carefully prepared: soil moisture is the key to affect seedling quality. The situation is good, the land is flat, the seeding depth is easy to be consistent, and the emergence is neat and uniform. An important part of the preparation before planting is the adjustment of soil moisture. In Huanghuaixia and interplanting summer corn areas, seasonal drought often occurs after wheat harvest, and the water quality deteriorates when corn is sown. Therefore, buckwheat yellow water is often used to supplement the bottom mash.
Proper close planting and determination of sowing volume: Reasonable density should consider the characteristics of varieties. Second, if the soil fertility, the amount of fertilizer is large and reasonable, the suitable density is large. In areas that are prone to drought and no irrigation, planting densities should be thin.
The calculation method of corn sowing amount is as follows: Seed use quantity (kg) = sowing density per hole grain weight area. Should focus on the development of corn seeding technology, improve the quality of sowing.
Determine the sowing depth: sowing depth is generally 5cm-6cm. In clays with good lyrical content, suitable shallow sowing should be appropriate, preferably 4cm-5cm. Loose sandy loam should be properly sowed in depth, preferably 6cm-8cm. If the soil moisture is large, it should not be broadcast in depth, and the soil should be properly broadcasted.
Post-suppression after sowing: After sowing, it is necessary to suppress the soil after sowing, and to repress it when it is dry. When there is too much soil moisture, do not suppress it.
Appropriate application of seed fertilizer: Appropriate application of seed fertilizer can provide nutrients for seedlings to raise feet, promote seedling growth and enhance resistance to drought, low temperature, disease and other adverse factors. Fertilizer includes a small amount of nitrogen fertilizer, phosphate fertilizer, potash fertilizer and trace element fertilizer. Fertilizer use to control the amount and isolation of seed fertilizer, so as not to burn seedlings. General Mushi 5kg-8kg diammonium phosphate, the effect is good.
If there are few seedlings after planting, but there is no obvious lack of ridges and ridges, you can leave the two strains to make up the density when the seedlings are close to the seedlings; Plant shade-tolerant crops such as soybeans and potatoes. If only half of the seedlings emerge, intercropping crops can be sown. When the emergence is less than half, it is recommended that the replant be destroyed.
Lentils, scientific name lentils (Lens culinaris) annual raw herbs or more years.Also known as marina Beans, corns, beans.One crop and green manure crops.The chromosome number of 2 n = 14.Originated in southwest Asia and eastern Mediterranean.Neolithic cultivation.About the Bronze Age spread to the Mediterranean, Asia and Europe and other regions.About 40 countries in the world culture lentils, most Asian production.Points, large and small grain of two subspecies, southern Europe, north Africa and the americas are mainly large subspecies of the cultivation, South Asia and eastern Europe are mostly small grain of subspecies.
