Problems solved by technology

At present, there are many kinds of plant growth regulators used in production, among which ethephon, maize virulin, and chlormequat are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit ear growth and reduce yield; three. Decyl alcohol, brassinolide, etc. can improve photosynthetic performance, but cannot effectively prevent lodging

Abstract

The invention relates to a corn lodging resistant production-increase adjusting agent, comprising plant growth adjusting agent, polyamino acid, organic acid, and microelements. The inventive production comprises that using solvent to dissolve the organic acid, and dissolve the plant growth adjusting agent, microelements and polyamino acid, making volume constant. The inventive adjusting agent can be diluted to be sprayed on the leaves of corn, to optimize the shape and yield of corn, to improve the anti-lodge ability of corn and improve the production.

Description

【Technical field】 [0001] The invention belongs to the field of pesticides, and relates to a corn lodging resistance and yield-increasing regulator as well as a preparation method and application thereof. 【Background technique】 [0002] Corn is an important food crop, the pillar of the development of animal husbandry, and its position in industrial processing is becoming more and more prominent. According to statistics, the proportion of feed corn consumption in my country's total corn consumption rose from 65% in 1992 to 72% in 2001. According to the "10th Five-Year Plan of Animal Husbandry and 2015 Long-term Target Planning", the consumption of feed corn in my country will reach more than 105 million tons by 2007, an increase of more than 22 million tons (26.5% increase) compared with 2001. The demand for corn in industrial development is increasing year by year, and high and stable yield is the main direction of corn industry development. [0003] In corn production, incr...
