Sugarcane root-promoting lodging-resistant yield-increasing regulator and preparation method and application thereof

Abstract

The invention relates to a sugarcane root-promoting lodging-resistant yield-increasing regulator and a preparation method and application thereof. The regulator comprises the following components: 15-20 g/L of sodium naphthalene acetate, 50-80 g/L of hymexazol, 110-150 g/L of ethephon, 5-20 g/L of an active agent and a spreader, and 730-820 g/L of water, wherein the active agent and the spreader are selected from one or more of Tween 20, Tween 60 and triton. The regulator can significantly increase the quantity of seed roots and seedling roots of sugarcane, and the root system is developed; the tillering force is strong, the stem rate is high, the stalks are thick and strong, the lodging resistance is strong, and the sugar content and the sugar yield are high; the lodging rate of sugarcaneis reduced by 17.40%-37.50%, the acre yield is increased by 11.67%-51.20%, the acre sugar yield is increased by 14.62%-55.19%, and the sugar content of sugarcane stems is increased by 4% or above. Meanwhile, the product has the characteristics of low cost, convenience in use, few field residues and the like, is easy to popularize and apply, and has a positive promotion effect on sugarcane production in China.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a preparation method and application of a sugarcane root-stimulating, lodging-resistant, and yield-increasing regulator. Background technique [0002] Sugarcane is the main sugar crop, and sucrose is an indispensable food in the life of our people. Sugarcane likes temperature, humidity, and fertilizer, and has a long growing season. It is mainly distributed in tropical and subtropical regions south of 24° north latitude, such as Guangxi, Guangdong, Taiwan, Fujian, Hainan, Yunnan, and Sichuan. During the growth of sugarcane, frequent typhoons, monsoons and heavy rainfall often lead to large-scale lodging of sugarcane, which seriously affects the yield and quality of sugarcane, directly affects the supply of sucrose in people's daily life, and affects the development of sugarcane industry. Therefore, it is of great practical significance for the sustainable development of the sugarcane ...

AI Technical Summary

Problems solved by technology

At present, there are many kinds of plant growth regulators used in production, among which ethephon and paclobutrazol are mainly used to reduce plant height and prevent lodging, but at the same time, the side effects are to limit the growth of stems and reduce the yield of cane stems and sucrose;30 Alkanols, brassinolides, etc. can improve photosynthetic performance and prevent premature aging, but cannot effectively prevent lodging
