Second, potassium dihydrogen phosphate. During the filling stage of wheat flowering, 100-200 g of potassium dihydrogen phosphate per acre and 75 kg of water spray can increase the photosynthetic capacity, promote nutrient conversion and transportation, and accelerate the filling speed. It can also resist wind and fall, prevent dry hot air, increase 1000-grain weight, and improve quality and output.
Third, multiple micro-fertilizers. In the wheat heading filling stage, about 100 grams of phosphorus, zinc, copper, potassium, magnesium and other trace elements per acre, 50 kg of water spray, can supplement nutrient deficiency, increase photosynthesis, increase seed setting rate, increase 1000-grain weight.
Fourth, spray amino acid compound micro-fertilizer. It is a high-efficiency nutrient organic compound fertilizer based on amino acids. It has the functions of full nutrition, high fertilizer efficiency, quick effect, disease resistance and drought resistance, lodging resistance, good yellowing, grain fullness, 1000-grain weight increase, yield increase, and high yield. Spraying 300-400 times of liquid in wheat jointing, booting stage and filling stage, the effect is very obvious.
Five, vinegar. The use of 300 grams of water to 40-50 kg of water can be sprayed in the late stage of wheat flowering to the early stage of grain filling, which can prevent wheat dry hot air and increase production by 8-10%.

First, urea. For the de-fertilized land, photosynthesis can be enhanced by nitrogen supplementation, and the second and third types of wheat fields can be promoted. Use 800-1000 grams of urea per acre, 50 kilograms of water, spray from the booting of wheat to the filling stage.
