Tree root fermented fertilizer for improving soil quality and preparation method thereof

Abstract

The invention belongs to the technical field of fermented fertilizers, and particularly relates to tree root fermented fertilizer for improving soil quality and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing pachira macrocarpa roots, roselle ferment, peanut bran and chicken manure in proportion, continuously adding other fermentation materials,mixing, putting the mixture into a transparent container with a small amount of holes, fermenting in a greenhouse at the temperature of 20-30 DEG C for 10-20 days until the temperature reaches 75-85DEG C, and continuously fermenting at constant temperature for 1-3 months to obtain the pachira macrocarpa organic fertilizer. The fermented fertilizer has the effect of improving the soil quality after being applied to soil, and can improve the activity of urease, acidic magnesium phosphate, catalase, sucrase and other enzyme substances in the soil to a certain extent, thereby improving the biological activity of the soil, stably providing nutrients for the soil and improving the physicochemical properties of the soil. Therefore, absorption of crop nutrients can be promoted, healthy growth ofcrop roots is promoted, and stability of the roots is maintained.

Description

technical field [0001] The invention belongs to the technical field of fermented fertilizers, and in particular relates to a root fermented fertilizer for improving soil quality and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and soil quality is a major factor in agricultural development. With the development of society, the problem of soil quality affecting the development of China's agriculture has become increasingly prominent. There are two main reasons for soil quality problems. One is the overload of agricultural soil due to the long-term use or overuse of soil arable land The second is that the fertilizers used in the planting process of crops remain in the soil, which will change the nature of the soil after long-term use. [0003] At present, the methods of soil improvement include soil water conservancy improvement, soil chemical improvement, soil cultivation improvement and soil biological improvement, e...

AI Technical Summary

Problems solved by technology

[0003] At present, the methods of soil improvement include soil water conservancy improvement, soil chemical improvement, soil cultivation improvement and soil biological improvement, etc. The existing technology mainly uses organic fertilizers to improve soil permeability and enhance plant fertility. , but organic fertilizers are likely to cause eutrophication of the soil and increase the burden on the soil. Some soil improvers are used to improve the soil structure, but the chemical improvement method will lead to the residue of chemical reagents, and long-term use is not conducive to the stability of soil fertility.
