The proportion of nitrogen, phosphorus and potassium fertilizer in wheat fields is different because the local conditions are different. Fertilization is generally recommended as follows:
High-yield fields should “control nitrogen, stabilize phosphorus, increase potassiumâ€; middle-yield fields should “stable nitrogen and increase phosphorusâ€; low-yield fields should “increase nitrogen and increase phosphorusâ€.
The application amount of chemical fertilizer is roughly as follows: the high-yield field generally applies 50-70 kg of standard nitrogen fertilizer, 40-50 kg of standard phosphate fertilizer, 10 kg of potassium fertilizer, and 1.5 kg of zinc fertilizer in the whole growth period. The medium-scale field generally applies standard nitrogen fertilizer 50-60. Kg, standard phosphate fertilizer 50 kg, potash fertilizer 5~10 kg; low-yield fields generally apply standard nitrogen fertilizer 40~50 kg and standard phosphate fertilizer 50 kg.
Apply all organic fertilizer, phosphate fertilizer and potassium fertilizer. Nitrogen fertilizer is 50% base application, and 50% is used for jointing and topdressing. We must vigorously promote the deep application of chemical fertilizers and resolutely put an end to the surface.
