Cold-resisting output increasing agent for corn

Abstract

The invention relates to a cold-resisting output increasing agent for corn. The cold-resisting output increasing agent for corn is formed in the manner of mixing the following raw materials by weight percent and then adding water and stirring. The raw materials include: 10-15% of phosphate fertilizer, 10-15% of cold-resisting nutrient, 8-10% of brassinolide, 8-10% of polyethylene glycol and 5-8% of cytokinin. The added water is 800-1200ml. The cold-resisting output increasing agent for corn is capable of boosting the growth of the plant, shortening the growth period, increasing the chlorophyll and unsaturated fatty acid of the plant, obviously promoting the cold resistance and disease resistance of the corn plant, prolonging the service life and increasing the yield.

Description

technical field [0001] The invention relates to agricultural chemicals, in particular to a corn cold-resistant yield-increasing agent. Background technique [0002] At present, the sown area of ​​corn in my country is about 300 million mu, second only to rice and wheat, and ranks third among food crops, second only to the United States in the world. Therefore corn is an important crop in life. [0003] Corn sowing to seedling encounters low temperature, delayed seedling emergence, weak and thin seedlings, reduced seed germination rate and germination vigor, etc., and hinders the growth of functional leaves of the plant. At the four-leaf stage, the plant is obviously short and shows growth. Delayed, the effective leaf area of ​​the functional leaves of the plant is significantly reduced and the photosynthetic capacity is reduced; from the fourth leaf stage to the silking stage, the low temperature lasts for a long time, and the plant height, stem, leaf area and dry matter we...

[0003] Corn sowing to seedling encounters low temperature, delayed seedling emergence, weak and thin seedlings, reduced seed germination rate and germination vigor, etc., and hinders the growth of functional leaves of the plant. At the four-leaf stage, the plant is obviously short and shows growth. Delayed, the effective leaf area of ​​the functional leaves of the plant is significantly reduced and the photosynthetic capacity is reduced; from the fourth leaf stage to the silking stage, the low temperature lasts for a long time, and the plant height, stem, leaf area and dry matter weight per plant are affected; silking to maturity Low temperature results in insufficient effective accumulated temperature, resulting in difficulty in pollination, prolonging the filling period, and slow accumulation of dry matter, resulting in reduced production
