The chemical control cultivation of corn began in recent years. The chemical regulators used mainly include Chemical Control II No. 20% EC, etc. This product has been demonstrated in more than 20 provinces and cities. The results of the promotion showed that after the use of Chemical Control II, the stalks were tough, the roots were developed, and the lodging resistance was enhanced. At the same time, the leaf color is deepened, the leaf is thickened, the chlorophyll content is increased, and the photosynthesis is enhanced. Generally, the plant height is reduced by 10-15 cm, and the ear position is reduced by 10-12 cm. At the same time, planting density can be increased, and 500 to 1000 plants can be added every 1/15 hectare. The leaf area coefficient of plants increased from 4 to 5.5, and the yield increase was generally 15% to 30%.
