Saline-alkali soil modifier prepared through vinegar residues

Abstract

The invention discloses a saline-alkali soil modifier prepared through vinegar residues, and relates to the technical field of soil modifiers. The modifier is prepared from, by weight, 10-15 parts of vinegar residues, 5-10 parts of distillers' grains, 4-8 parts of cane molasses, 90-100 parts of selenium-rich crop straw, 15-20 parts of coco coir, 10-15 parts of pomace, 10-15 parts of camellia oleosa seed oil, 8-12 parts of bean pulp, 6-10 parts of leaves of Illicium anisatum, 5-8 parts of yellow cinnamon leaves, 5-8 parts of maltodextrin, 4-6 parts of sanguisorba officinalis, 3-4 parts of silkworm chrysalis meal, 2-3 parts of bran-wax, 2-3 parts of zeolite powder, 1-2 parts of sodium silicate and 0.5-1 part of rare earth. Food leftovers including vinegar residues, distillers' grains, cane molasses, pomace and bean pulp serve as the raw materials, production cost is reduced, resources are reasonably utilized, and contained rich nutrients can sufficiently meet the growth requirement of crops.

Description

Technical field: [0001] The invention relates to the technical field of soil improvers, in particular to a soil improver for saline-alkali land prepared from vinegar grains. Background technique: [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares. 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. [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 ...

[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
