Problems solved by technology

At present, there are many kinds of plant growth regulators used in production, among which ethephon, maize turpentine, 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; naphthaleneacetic acid, kinetin, gibberellic acid, proline, etc. can improve stress resistance, but cannot effectively prevent lodging

Abstract

The invention relates to a maize lodging-resisting stress-resisting yield-increasing regulator, and a preparation method and application thereof. The regulator contains the following components: iminodisuccinic acid 140-280 g / L, ethephon 90-180 g / L, zinc sulfate heptahydrate 50-100 g / L, active agent also used as a spreading agent 5-10 g / L, and the balance of water. The active agent also used as the spreading agent is selected from one or more of Tween 20 and Tween 60. The regulator of the invention can significantly enhance the ability of maize such as resisting low-temperature chilling injury, high temperature, drought and mild saline-alkali stress, increase the lodging resistance of maize, increase the number of ears per mu, grain number per ear and thousand-grain weight, and increase the maize yield by 20% or more. At the same time, the regulator has the characteristics of low cost, convenient use, and less residues in the field. The regulator is easy to popularize and apply, and has a positive role in promoting China corn production.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a corn lodging and stress-resistant yield-increasing regulator as well as its preparation method and application. Background technique [0002] Corn is an important grain and feed crop with strong adaptability, wide distribution, multiple uses, and great potential for increasing production; as a grain crop, it is rich in nutrients such as sugar, protein, fat, and vitamins, and is the ration for the people to survive. The sown area ranks first in the world; as a feed crop, the grain is the first-class concentrated feed for livestock and poultry, and the stems and leaves are rich in cellulose, which plays a significant role in improving the yield and quality of pork, milk and egg products ; As an industrial raw material, corn starch is widely used in food, medicine, textile and other industrial sectors, with more than 500 kinds of industrial products. Therefore, corn is an important gra...
