Problems solved by technology

However, the soil type in this area is mainly red-yellow loam, which is acidic or even strongly acidic (pH4.5-5.5) soil, which has a low adsorption capacity for ions. Most of the soil is relatively barren and lacks trace elements. During the same period, there is more rain, which is prone to vigorous growth and lodging of the aboveground part during the flowering period and after flowering, which reduces the transportation and distribution of photosynthetic compounds to pods, resulting in empty and unfull peanut pods, resulting in a decline in peanut yield and quality
Patent 201110027434, the main ingredients are potassium pyrophosphate trihydrate, potassium sulfate, disodium octaborate tetrahydrate, ammonium molybdate monohydrate, 98% powder of amine fresh fat, and 97% powder of benzedramine, which has a reasonable supply of peanut growth and development period Nutrient elements are needed to control vegetative growth, promote reproductive growth, and shape ideal plant shape, but it is of little help to the vigorous growth and lodging of peanuts
And patent 200510090044, the microemulsion with methylpiperium and uniconazole as active ingredients can effectively regulate the growth and development of peanuts, control the elongation of peanut stem nodes, and prevent vigorous growth and lodging. not so useful

Abstract

The invention discloses an agent for controlling excessive vegetative growth and strengthening seedlings of peanuts and a preparation method and an application of the agent. By taking silicate, mepiquat chloride and uniconazole as effective components, 1-10% of silicate, 10-50% of mepiquat chloride, 0.1-5% of uniconazole and 1-50% of an assistant and soluble filler are evenly mixed and ground to obtain the agent for controlling excessive vegetative growth and strengthening seedlings of peanuts; and by utilizing the stress resistance of the silicate and the characteristic of coordinated nutrient utilization, the absorption and the utilization of elements such as N, P and K in soil caused by peanut root systems are promoted, the capability of photosynthesis of the peanut is enhanced, the problems of excessive vegetative growth and lodging of aboveground parts are effectively controlled by matching with the mepiquat chloride and the uniconazole for adjusting the development process of the peanut, the seed setting rate and the grain plumpness rate of the peanut are increased, and the problems of soil nutrient deficiencies and excessive vegetative growth and lodging of the peanut in the south region of China are effectively solved. The prepared agent for controlling excessive vegetative growth and strengthening seedlings of peanuts can effectively improve the stress resistance of the peanut, has a good yield-increasing effect, and is simple in production process, simple and convenient in using method, and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to an agent for controlling growth and strengthening of peanuts and a preparation method and application thereof. Background technique [0002] Peanut (Arachis hypogaea L.) is an important oil crop, economic crop and foreign exchange earning crop in China. It plays an important role in my country's edible oil supply, food processing, export earning foreign exchange and farmers' income increase. South China is one of the main peanut producing areas in my country, with important resource advantages and location advantages. However, the soil type in this area is mainly red-yellow loam, which is acidic or even strongly acidic (pH4.5-5.5) soil, which has a low adsorption capacity for ions. Most of the soil is relatively barren and lacks trace elements. During the same period, there is more rain, which is prone to vigorous growth and lodging of the shoots during flowering...
