"Where wheat is rich, it's good to be rich." To do a good job in this year's wheat planting, improve the quality of sowing, and ensure that all seedlings and seedlings are seeded. To this end, we must grasp the following five key points in planting:
First, turn off the fine ground preparation. Fine soil preparation is the basis for the healthy growth of wheat. For this reason, the site preparation should be combined with deep plowing and ploughing, requiring deep plowing of 20-27 cm to destroy the ploughing layer caused by rotary tillage. After the cultivation or rotation, the land must be repressed so that the topsoil will be finely crushed, and there will be no overhead phenomenon. Virtual reality, but also to be smooth, conducive to uniform watering later, emergence and neat.
Second, the appropriate amount of sowing off the appropriate period. Combining the climatic characteristics of the past few years and the characteristics of wheat breeding, the appropriate sowing date for semi-winter cultivars is from October 1st to 15th, and the suitable sowing date for weak spring cultivars is from October 10th to 20th. Early-middle high-yielding plots, 6- to 8-kilograms per mu, 8-10 kilograms per mu in late flooded fields, more than two days after sowing date, 0.5 kilograms more sowing, and clay land suitable for broadcast Based on quantity, the appropriate increase in broadcast volume. Seeding methods can be used in large and small rows, such as “three dense and one thin†or “two dense and one thin†planting methods.
Third, the prevention and control of pests and diseases. Seeds sown are preferably coated with seeds and treated with soil. In combination with land preparation, ground pests, and midge pests, use 3% methylisothiphos or phoxim granules in an amount of 2 to 3 kg/mu, mix 20 kg of dry fine soil, and spread the ground uniformly before plowing. Ground into the soil. If it is not a coated seed, it must be seeded with pesticides to prevent and control underground pests and diseases. Select insecticides, methylisothiphos and phoxim, for seed dressing, mix 40% methylisoprophos with water, seeds in a ratio of 1:80:800 to 1000, and 50% phoxim by 1:50 ~ 100: 500 ~ 1000 drugs, water, seed dressing ratio, heap stuffy 2 ~ 3 hours after sowing.
Fourth, the application of base fertilizer off. The fertilization of wheat must adhere to the principle of combining organic fertilizer and inorganic fertilizer, combined application of nitrogen, phosphorus and potassium, promote soil testing, formula fertilization and straw returning to improve fertilizer utilization. General Mushi organic fertilizer 3000 ~ 4000 kg, Mushi urea 20 ~ 25 kg, superphosphate 50 ~ 60 kg, potassium chloride 12 ~ 15 kg or wheat formula fertilizer 40 ~ 50 kg. Organic fertilizers, phosphate fertilizers, and potash fertilizers are all used as base fertilizers, nitrogen fertilizers are used as base fertilizers at 60% to 70%, and 30% to 40% of nitrogen fertilizers are combined with irrigation to apply fertilizers before jointing. For the field where the straw is returned to the field, supplementation is carried out at a rate of 10 kg of ammonium bicarbonate applied per 100 kg of straw to avoid nitrogen deficiency during the seedling stage.
Fifth, the good Miao Miao Qi Guan. After sowing wheat, it is necessary to promptly check the emergence of seedlings. Once the seedlings are found to lack seedlings, they should be filled in time. First, replant, select the same variety as the lack of seedling plots, and sow the seed after treatment to facilitate emergence and growth. The second is transplanting. For the lands that are not ready for replanting and replanting, there is still a shortage of seedlings. The strong seedlings of the same variety can be transplanted during the wheat tillering period. Watering and loosening can be done in time after transplanting. The latest can not be later than the light snow, in order to ease the winter wheat and winter, lay the foundation for the wheat harvest.
