1. Urea. 750-1000 grams of urea per acre, plus 50 kilograms of water, sprayed from the booting stage of wheat to the filling stage. For the de-fertilized plot, photosynthesis can be enhanced by nitrogen supplementation, and the second and third types of wheat fields can be promoted.
2. Potassium dihydrogen phosphate. During the period from the flowering to the filling stage of wheat, spray 100-200 g of potassium dihydrogen phosphate per acre with 75 kg of water to increase the photosynthetic capacity, promote nutrient conversion and transportation, and accelerate the filling speed. It can resist wind and fall, prevent dry hot air, increase production and quality, and increase 1000-grain weight.
3, multiple micro-fertilizer. In wheat heading grouting, about 100 grams of phosphorus, zinc, copper, potassium, magnesium and other trace elements per acre, plus 50 kg of water spray, can supplement nutrient deficiency, increase photosynthesis, increase seed setting rate, increase 1000-grain weight.
4, 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. Spray 300-400 times of liquid in wheat jointing, booting stage and filling stage.
5, vinegar. The use of 300 grams of water to 40-50 kilograms of water can be sprayed from the late stage of wheat flowering to the early stage of grain filling, which can prevent dry heat of wheat and increase yield by 9%.
