Soil improver containing coconut chaff and preparation method thereof

Abstract

The invention relates to a soil improver containing coconut chaff and a preparation method thereof, and relates to a soil improver. The soil improver containing the coconut chaff comprises the following components by weight percent: 0.75 to 0.92 percent of coconut chaff, 0.05 to 0.1 percent of diatomite, 0.01 to 0.05 percent of polyaspartic acid, 0.01 to 0.05 percent of humic acid, 0.005 to 0.03 percent of polyacrylamide and 0.005 to 0.02 percent of boric acid. The preparation method comprises the following steps: (1) dissolving polyacrylamide, polyaspartic acid and boric acid in water to obtain a mixed solution; (2) uniformly mixing powdered coconut chaff, diatomite and humic acid to obtain a solid powdered mixture; (3) spraying the mixed solution obtained in the step (1) into the solid powdered mixture obtained in the step (2), mixing, and air-drying to obtain the soil improver containing the coconut chaff. The production cost is low, raw materials are environmentally friendly and non-toxic, the secondary salinization and hardened soil can be effectively improved, and the productivity of the earth can be restored and improved.

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.
