To achieve strong quality and high yields, we must have high soil fertility and good soil, fertilizer, and water conditions to ensure that the soil is deep and flat, with more than 1% organic matter in the tillage layer, and about 0.1% total nitrogen, and available phosphorus. 25 mg/kg or more, and quick-acting potassium 80 mg/kg or more. According to the measurement, for every 100 kg of wheat grain produced, 3 kg of pure nitrogen, 52.5 kg of P2O5, 2.5 kg of K2O5, and 500-600 kg of wheat produced per acre are required, and 15.18 kg of pure nitrogen and P2O6.25-7.5 kg are required. K2O12.5-15 kg, pure sulfur 3-4 kg, pure zinc 1-1.5 kg.
When strong wheat production is required, more than 5,000 kg of organic manure, 12-14 kg of pure nitrogen, P2O10-12 kg, and K2O7-8 kg are required. The "pre-heavy and light" fertilization method was adopted, that is, all organic fertilizers, phosphate fertilizers, potash fertilizers, trace fertilizers, and 50-60% nitrogen fertilizers were used as base fertilizers, and 40-50% of the single fertilizers were topdressed at the jointing stage.
