Basal fertilizer: The application of wheat basal fertilizer is an important measure to improve the soil fertility of wheat field. It can ensure the growth of wheat seedlings to the needs of nutrients, promote early growth, and make the wheat seedlings grow strong and strong roots before the winter, and for the spring After the growth laid the foundation. The wheat basal fertilizer is mainly farmyard manure, and the appropriate amount of nitrogen, phosphorus and potassium chemical fertilizers are applied. The amount of basal fertilizer should be based on the type of fertilizer required, nature, soil, etc. Generally Mushi farmyard fertilizer is 1000-1500 kg, urea is 10 kg, and 45% compound fertilizer is 25 kg. It is applied in combination with site preparation before sowing.
Seed Fertilizer: Using appropriate amount of available nitrogen and phosphate fertilizer as seed fertilizer during wheat sowing can promote rooting and emergence of wheat, increase tillering, increase yield, and have significant yield increase effect on wheat fields with insufficient buckwheat and base fertilizer. The use of thiamine as a seed fertilizer can increase production by about 10%. Nitrogen fertilizer is used as a seed fertilizer. Generally, 5 kg of thiamine or 2.5 kg of urea per acre is used. Phosphate fertilizer is used as a seed fertilizer, and superphosphate is sprinkled on the soil surface after shallow ploughing. Mix soil and then sow, generally use 5~8 kg of superphosphate per acre, ammonium bicarbonate volatile cause seed burns can not be used as seed fertilizer, soil fertility or basal adequate fields, fertilizer can not be applied.
Topdressing: According to the needs of nutrients at each growth and development stage of wheat, top dressing in stages is an important measure to obtain high yields.
Top-dressing Miaofei: At the beginning of the emergence of the tiller, apply 5~10kg of ammonium per acre or 3~5kg of urea or a small amount of human excreta to promote seedling growth and increase tillering, especially for the basic seedlings. Insufficient or late sowing of wheat, early application of Miaofei effect is good, but for the base fertilizer and seed fertilizer more adequate wheat, Miaofei can not Shi.
Re-applied wax fertilizer: wax fertilizer is based on the application of semi-efficient and slow-lasting man-made fertilizers. For the three types of seedlings, quick-acting fertilizers should be used to promote long-term rooting, grow into strong seedlings, and promote three types of seedlings. Lightweight and upgrade quickly.
See Miao Shi good to return green manure: For poor fertility, base fertilizer is insufficient, sowing late, before winter, tiller less, growing weaker wheat field should be applied early or heavy application of green manure, usually spread 5 ~ 10 kg of urea per acre.
Application of joint fertilizer: Dipstick fertilizer is applied after the peak of wheat tiller, and promotes the formation of panicle into big panicle, improves the rate of spike formation, promotes the differentiation of floret, and strives for panicle large grain fullness. Generally, about 40% compound fertilizer is applied to 20 kg per acre.
Fertility panicles: Fertilizers are mainly nitrogenous fertilizers with a small amount, and generally apply 3 to 5 kg of urea per acre.
Late fertilization: After the heading of wheat, certain elements such as nitrogen and phosphorus are still required. At this time, the aging ability of wheat roots is weakened. Therefore, the method of extra-root fertilizer is generally adopted. In the early stage of wheat grain filling combined with the prevention and treatment of wheat ear blast, spraying 1% urea and 0.2% potassium dihydrogen phosphate solution 30-40 kg per acre can effectively improve the ability of wheat to resist dry hot wind, delay leaf senescence and increase grain weight. To achieve the purpose of increasing production.
