Mixture for improving soybeans' availability of phosphorus sources and application thereof

Abstract

Belonging to the agronomic technologies, the invention relates to a method for improving soybeans' availability of phosphorus sources. The mixture is formed by compatibility and mixing of an organic phosphorus source calcium phytate and an inorganic phosphorus source phosphate rock powder with the same phosphorus content. The mixture can be applied to increase the planted soybeans' availability of insoluble phosphorus sources. According to a use method, the mixture is sprayed into soil. The invention enhances the available phosphorous content of soil and soybeans' availability of phosphorus sources, and ensures and promotes the growth, development and metabolism biological process of soybean crops.

Description

technical field [0001] The invention belongs to agronomic technology, and mainly relates to a mixture and an application method for improving the utilization rate of phosphorus sources by soybeans. Background technique [0002] Phosphorus can participate in various physiological growth processes in plants in various ways, and is an important component of plants, which is of great significance to the growth, development and metabolism of plants. A large amount of phosphorus is accumulated in the soil, but crops can only take away a small amount of phosphorus from the soil. After the phosphorus fertilizer is applied to the soil, due to the different properties and compositions of the soil, various complex physical and chemical reactions occur between the phosphorus fertilizer and the soil, forming a series of new Phosphate compounds, so the phosphorus absorbed by plants is not the compound contained in the phosphorus fertilizer, but a new product formed after the reaction. The...

A large amount of phosphorus is accumulated in the soil, but crops can only take away a small amount of phosphorus from the soil. After the phosphorus fertilizer is applied to the soil, due to the different properties and compositions of the soil, various complex physical and chemical reactions between the phosphorus fertilizer and the soil occur, forming a series of new Phosphate compounds, so the phosphorus absorbed by plants is not the compound contained in the phosphorus fertilizer, but a new product formed after the reaction. Therefore, generally speaking, there is no shortage of phosphorus in the soil after a large amount of fertilization, but it is lacking to the plants. available phosphorus
