Problems solved by technology

There are many defects in the existing soil improver. On the one hand, the existing soil improver has a single active ingredient, which is easy to cause soil compaction, which is not conducive to the development and growth of the root system of crops; on the other hand, the existing soil improver is too expensive to produce. suitable for wide application

Abstract

A disclosed modifier applied to soil is prepared from the following raw materials in parts by weight: 15-25 parts of potash feldspar, 20-40 parts of calcium sulfate dihydrate, 5-15 parts of Ammonium hydrogen sulfate, 4-8 parts of anhydrous calcium sulfate, 9-18 parts of montmorillonite, 9-12 parts of pyrite, 8-16 parts of oxalic acid, 3-9 parts of phosphor, 6-12 parts of ion exchange resin, 5-8 parts of potassium, 7-10 parts of a trace element, 20-30 parts of meerschaum, 10-20 parts of malm and 3-5 parts of hydrolysable nitrogen. The provided modifier applied to soil is reasonable in ratio and small in usage amount, and is capable of retaining water, fixing nitrogen, preventing soil from being hardened, improving soil gelation ratio and adjusting soil pH value.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver. Background technique [0002] In recent years, with the increase of agricultural production activities and the excessive use of chemical fertilizers, the soil structure has been destroyed, resulting in soil compaction, low yield and poor quality of agricultural products, and people's consumption is harmful to human health. At the same time, there are large areas of sandy soil, saline-alkali land, acid soil, rocky desert land, desert land, soaked swamp land and other common soils in China. These soils are not suitable for planting crops or other crops, resulting in waste of land resources. At present, in order to maintain soil nutrients from depletion, it is necessary to apply soil amendments to poor soil to improve the physical, chemical and biological properties of the soil to make it more suitable for plant growth. There are many defects in the existi...
