Spring Wheat Fertilization Technology
To promote the high yield, high quality, high efficiency and resource conservation of wheat, according to different types of wheat demand fertilizer law and the status of wheat soil fertilization, based on the application of organic fertilizer, rational use of chemical fertilizers, improve fertilizer utilization, reduce soil pollution. The general high-yielding fields control nitrogen, stabilize phosphorus, increase potassium, supplement micro crops, stabilize nitrogen in the middle-yield field, increase phosphorus, and make additional potassium fertilizers. Fertilization technology points: 1, high and medium wheat fields High-yield wheat fields have high soil fertility, good production conditions, and annual N fertilizer input Large, but relatively insufficient potassium investment. In the fertilization, it is necessary to increase the input of organic fertilizer, and fully implement the straw to return the field. According to the principle of controlling nitrogen and stabilizing the phosphorus and increasing the potassium, the high-yield wheat field (above 500kg/mu) will be applied to the organic fertilizer and the pure nitrogen (N)14. - 17kg, phosphorus (P2O5) 8-10kg, potassium (K2O) 8-10kg; fertilizer application on one-time application of phosphate fertilizer, 30% nitrogen fertilizer application, 60% jointing at the jointing stage, 10% in the booting stage of wheat, potassium fertilizer 70% end-use, 30% top-dressing period. In the medium-sized wheat field, Mushi organic fertilizer 3.5 square root, pure nitrogen (N) 12-15kg, phosphorus (P2O5) 7-8kg, and potassium (K2O) 5-8kg; 40% nitrogen fertilizer application and 60% jointing fertilizer application, 70% of potash fertilizer is applied, 30% of joint fertilizer is applied at the jointing stage, and phosphate fertilizer is applied once. The application of micro-fertilizer can use zinc sulfate or manganese sulfate seed dressing, fertilizer per kilogram of seed 2-4g. Potassium dihydrogen phosphate was sprayed in the middle and late stages of wheat growth to increase the 1000-grain weight of wheat. 2, late broadcast wheat field The late-seeding wheat field was delayed due to late cultivating, delayed after sowing, and insufficient accumulated temperature before winter. It was necessary to regenerate and promote seedlings so as to achieve the goal of strong seedlings in the winter and rapid transformation in the spring. High-yield field Mushi organic fertilizer more than 3 square, pure nitrogen (N) 14-15kg, potassium (K2O) 6-7kg, phosphorus (P2O5) 8-9kg; middle yield Mushi organic fertilizer more than 3 square, pure nitrogen (N) 12- 14kg, phosphorus (P2O5) 6-7kg, potassium (K2O) 5-6kg. Fertilization method on the nitrogen fertilizer 40% -50%, the end of application, 60% -50% topdressing phase, phosphorus and potassium fertilizer is suitable for one-time application. In the middle and late period, the targeted foliage was sprayed with multiple microelement fertilizers. In addition, due to the large consumption of potassium in the cotton-cotton intercropping area, the amount of potash fertilizer can be appropriately increased.
