Biological soil improving agent and preparation method thereof

Abstract

The invention discloses a biological soil improving agent. The biological soil improving agent is prepared by mixing a component A, a component B and a component C, wherein the component A comprises humic acid, strong base and water; the component B comprises Enhance, Goldlabelreact, Liquajipmg, Penmax and water; the component C comprises DA-6 or sodium nitrophenolate, cytokinin and water and canalso comprises polyhydroxyalkanoate. The biological soil improving agent is organic multi-element concentrated multifunctional soil improving fertilizer, can fast supplement nitrogen and iron needed by soil and evidently increase soil buffer capacity, improve soil structure, improve soil hydrothermal performance and promote soil microorganism development at the same time, and is good in effect andquick in action when being used in the seedling stage and the early stage of planting, suitable for being applied to soil which is high in salt content, viscose and heavy in texture and poor in breathability and especially suitable for being applied to protected land such as greenhouses and saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a biological soil improver and a preparation method thereof. Background technique [0002] Today, with the rapid development of modern agriculture, due to the long-term overreliance on the effect of chemical fertilizers to increase production and the neglect of farm fertilizers, especially the excessive application of chemical fertilizers and the imbalance in the use of fertilizers, the internal structure of the agricultural system has been damaged, the organic matter content of the farmland plow layer soil has decreased, and the aggregate structure has been destroyed. and decrease, the water storage and fertilizer retention capacity decreases, and the fertilizer effect decreases; the decrease in soil moisture content affects the rate at which nutrients such as nitrogen and phosphorus move to the root system of crops through diffusion; the decrease in organic matter content...

[0002] Today, with the rapid development of modern agriculture, due to the long-term overreliance on the effect of chemical fertilizers to increase production and the neglect of farm fertilizers, especially the excessive application of chemical fertilizers and the imbalance in the use of fertilizers, the internal structure of the agricultural system has been damaged, the organic matter content of the farmland plow layer soil has decreased, and the aggregate structure has been destroyed. and decrease, the water storage and fertilizer retention capacity decreases, and the fertilizer effect decreases; the decrease in soil moisture content affects the rate at which nutrients such as nitrogen and phosphorus move to the root system of crops through diffusion; the decrease in organic matter content not only makes denitrifying bacteria strong, nitrogen fertilizers The loss in the form of gaseous nitrogen increases, and the remaining nitrate nitrogen in the soil leaks due to the difficulty in forming organic nitrogen, polluting groundwater

Due to the destruction of soil structure, the effective phosphorus content of phosphorus fertilizers decreases, and due to a large amount of adsorption on the surface of soil particles, phosphorus fertilizers are lost with farmland drainage and surface runoff, reducing the effective use of fertilizers
