Novel soil modifier

Abstract

The invention discloses a novel soil modifier. The novel soil modifier is prepared from, by weight, 5-25 parts of vinegar residues, 3-20 parts of potassium feldspar, 80-110 parts of straw, 1-15 parts of rare earth silico-calcium mineral substance, 1-10 parts of asparagus residues, 5-25 parts of pomace, 3-20 parts of saw dust, 3-20 parts of bean pulp, 1-12 parts of charcoal, 1-14 parts of yellow cinnamon leaves, 1-10 parts of polymerization amino acid, 1-6 parts of citric acid, 1-15 parts of garden burnet roots, 0.1-3 parts of water-retaining agent, 1-10 parts of rice bran wax, 1-10 parts of sodium silicate and 0.1-5 parts of polymaleic acid. The novel soil modifier has the functions of reducing the pH of soil, improving the physical structure of the soil and increasing soil fertility; when the novel soil modifier is applied in the plant growth earlier stage, the desalting effect is remarkable, the influence of salt damage on plant seedling emergence can be effectively reduced, the production cost can be reduced, the nutrient substances of the soil modifier are effectively enriched, and the growth needs of crops are met.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a novel soil improver. Background technique [0002] Saline-alkali land (soil) is a general term for salinized soil, alkaline soil and saline-alkali soil. The salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. In the process of utilization of saline-alkali land, simply put, it can be divided into light saline-alkali land, moderate saline-alkali land and heavy saline-alkali land. Light saline-alkali land means that its emergence rate is 70%-80...

Problems solved by technology

[0003] The traditional method to reduce the pH value of saline-alkali land is to irrigate the salt with fresh water, but this can only temporarily adjust the pH value of the soil, and cannot fundamentally improve the physical and chemical properties of the soil

Also, some soil amendments for saline soils are only aimed at lowering the pH without also focusing on the nutritional needs of the soil
