A kind of corn growth chemical regulator and its application method

Abstract

The invention discloses a chemical regulator for corn growth. Each 1 kg of the chemical regulator consists of the following substances: 18-22 mg of gibberellin, 10-20 g of potassium dihydrogen carbonate, 10-20 g of urea, 5-15 g of amino acid foliar fertilizer, Brassinolide 0.1-0.5mg, the balance is water. The product of the invention improves the pollination rate and yield of corn by shortening the male-female interval period of maize tasseling and silking, and meanwhile, the regulating agent of the invention also helps to improve the corn filling rate, accelerates grain filling, and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of corn growth regulating compositions, and in particular relates to a chemical regulator of corn growth and a using method thereof. Background technique [0002] Corn is the largest food crop in my country and the main field for the further development of food security. In the "National Food Security Mid- and Long-Term Planning Outline", especially the "National Plan for Increasing the Production Capacity of 100 Billion Catties of Grain", Henan has undertaken the task of increasing production by 15.5 billion catties, which is one-seventh of the country. Among them, corn accounted for 8.8 billion catties, accounting for 56.8% of the province's newly added grain. By 2012, Henan Province has successfully achieved nine consecutive increases in summer grain and ten consecutive increases in autumn grain. As far as corn production is concerned, the continuous increase in production is mainly due to the increase ...

Problems solved by technology

As a C4 crop with high light efficiency, corn is prone to photoinhibition under rainy and low-light conditions, which reduces the photosynthetic production capacity of corn and seriously affects grain filling, resulting in a decrease in corn yield.

Spraying plant growth regulators is currently one of the main means to obtain high yield by improving the stress resistance of crops. The predecessors have conducted a lot of research on the application of chemical growth regulators in corn production, mainly focusing on improving the lodging resistance of corn , anti-aging and other directions, but there is no report on how to achieve high and stable yield of maize through chemical regulation under low light conditions
