Plant growth regulating composition and preparation and application thereof

Abstract

The invention provides a plant growth regulating composition including amino acid and mepiquat chloride; amino acid is selected from any one or more of aspartic acid, threonine, serine, glutamic acid, glycine, alanine, cystine, valine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine, histidine, arginine, tryptophan and proline, and the mass ratio of mepiquat chloride to amino acid is selected to be 1 to (1-3); the composition is applied to vegetables, not only can improve the yield of the vegetables, but also can improve the quality of the vegetables.

Description

technical field [0001] The pesticide field of the present invention particularly relates to a plant growth regulating composition and its preparation and application. Background technique [0002] Vegetables are indispensable means of subsistence for human beings, non-staple food necessary for people's daily life, and special fresh agricultural products at the same time. The vegetable industry has a unique position and advantages in China's agricultural and rural economic development, and is the most dynamic in the planting industry. Since the reform and opening up, my country's vegetable industry has developed rapidly. Taking 2002 as an example, the total output value of vegetables at the current price has reached 368.22 billion yuan, second only to grain (519.97 billion yuan), far higher than fruit (more than 120 billion yuan). ), oilseeds (68.14 billion yuan), cotton (52.49 billion yuan), tobacco (19.44 billion yuan) and other crops, the vegetable planting area accounts f...

AI Technical Summary

Problems solved by technology

However, by increasing the planting density of vegetables and relying on group advantages to strive for higher yields, although the yield can be increased appropriately, due to the increase in planting density, they are often subject to adversities such as drought, high temperature, low temperature, and wind and rain attacks during the growth and development period. The harm of stress is often prone to a series of problems such as plant growth, slender stems, and lodging, which lead to poor yield increase effects; although the application of nitrogen, phosphorus, and potassium fertilizers can provide a large amount of elements needed for vegetable growth and achieve a certain yield increase effect, but Due to the inability to control vegetative growth, it is prone to a series of problems such as crazy growth of stems and leaves, delayed flowering and fruiting, and less pods, and improper application is prone to problems such as burning seedlings, soil compaction, and low fertilizer absorption rate, resulting in poor yield increase effects, and poor fruit quality
