Problems solved by technology

At present, there are many kinds of plant growth regulators used in production. Among them, ethephon, maizetrol, paclobutrazol, and chlormequat are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit ear development and reduce yield. ; Triacontanol, brassinolide, etc. can improve photosynthetic performance and prevent premature aging, but cannot effectively prevent lodging

Abstract

The invention relates to a lodging and senility resisting, high photosynthetic efficiency and yield increasing regulator for corn, and a preparation method and an application thereof. The regulator contains 5-aminolevulinic acid, 2-(3,4-dichlorophenoxy)triethylamine and ethephon, and preferably contains an activator and a spreader, and the activator and the spreader are selected from one or more of tween20 and tween60. The regulator can substantially enhance the low temperature cold injury, high temperature, drought and low light stress resistance of corn, increases the effective spike number, the number of grains per spike and the thousand-grain weight of the corn, and increases the output of the corn by 20% or above. The regulator has the characteristics of low cost, use convenience and less field residual, is easy to promote and apply, and has an active promotion effect on Chinese corn production.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a corn anti-lodging and anti-aging high-light-efficiency yield-increasing regulator, a preparation method and application thereof. Background technique [0002] Corn is an important grain and feed crop, the pillar of the development of animal husbandry, and its position in industrial processing is becoming more and more prominent. At present, my country's corn planting area is about 540 million mu, with a total output of about 215 million tons. The planting area and total output are second only to the United States, ranking second in the world. Corn is widely distributed in my country, mainly concentrated in Northeast China, North China and Southwest China. The provinces with the largest planting area are Heilongjiang, Jilin, Liaoning, Hebei, Shandong, Henan and Sichuan provinces. Among them, 360 million mu of spring corn is produced, with a yield of 405 kg / mu; 180 million mu of sum...
