Chemically controlled cultivation is a new technology in agricultural production. Wheat can be controlled and cultivated, and it can regulate and control the growth and development of plants and enhance the resistance to stress. Effective ways are: 1. Spray paclobutrazol wheat during the period of growth, mu 200ppm paclobutrazol solution sprayed 30 kilograms, can make the plant dwarf, increased lodging resistance, and can also treat wheat powdery mildew and increase plant nitrogen absorption and utilization. 2. In the early stage of jointing, sprayed CCC on groups of large and prosperous wheat fields sprays 50 to 70 kilograms of chlorella solution 0.13% to 0.3% per acre, which effectively inhibits internode elongation and dwarfs the plants. The base of the stem is rough to prevent lodging. If mixed with 2,4-D-butyl ester, it can also treat broad-leaved weeds. 3. In the jointing stage of wheat, spray strength promoters use 15 ml to 20 ml per mu to spray 20 kg to 60 kg of water, which can inhibit internode elongation, prevent late lodging, and increase production by 10%. 20%.
