A kind of soil conditioner containing coconut bran and preparation method thereof

Abstract

A soil conditioner containing coir peat and a preparation method thereof relate to a soil conditioner. The soil improver containing coconut bran is composed of the following components by mass ratio: coconut bran 0.75-0.92, diatomaceous earth 0.05-0.1, polyaspartic acid 0.01-0.05, humic acid 0.01-0.05, polyacrylamide 0.005 ~0.03, boric acid 0.005~0.02. Preparation method: 1) dissolving polyacrylamide, polyaspartic acid and boric acid in water to obtain a mixed solution; 2) uniformly mixing powdered coconut bran, diatomaceous earth and humic acid to obtain a solid powder mixture; 3 ) Spray the mixed solution obtained in step 1) into the solid powder mixture obtained in step 2), and dry after mixing to obtain a soil conditioner containing coconut bran. The production cost is low, the raw material is environmentally friendly and non-toxic, and can effectively improve secondary salinization and compacted soil, restore and increase land productivity.

Description

technical field [0001] The invention relates to a soil improver, in particular to a soil improver containing coconut bran and a preparation method thereof. Background technique [0002] Secondary salinization is the process of soil salinization caused by unreasonable cultivation, irrigation and excessive fertilization. The content of organic matter in soil is an important indicator of soil fertility and aggregate structure, and the reduction of organic matter leads to soil compaction. my country's agricultural arable land area is limited, and in recent years, with the application of a large amount of inorganic fertilizers, irrational irrigation and the acceleration of urbanization, non-agricultural development and occupation of arable land and other artificial and unreasonable factors have led to sand petrification of arable land around urban areas, Problems such as secondary salinization and soil compaction are intensifying day by day, with characteristics such as high pH v...

Problems solved by technology

[0003] Chinese patent application 201410163914.X discloses a mineral soil conditioner, which is composed of limestone, humic acid, diatomaceous earth, etc. in a certain proportion; but the amount of humic acid is 30%, and the amount of soil conditioner used Large, complex manufacturing process, resulting in high application costs

However, this kind of fertilizer to prevent soil compaction requires a large amount of humic acid, and the cost is high, and the industrialization and application of the improvement effect has certain limitations.
