Biological fertilizer for removing alkalis and restraining salts

Abstract

A disclosed biological fertilizer for removing alkalis and restraining salts is characterized by comprising the following substances in parts by weight: 60-70 parts of peat, 150-200 parts of corn straw, 9-11 parts of semen cassiae, 2-8 parts of medulla junci, 12-23 parts of potassium polymetaphosphate, 12-25 parts of ammonium bicarbonate, 12-20 parts of rock phosphate powder, 0.1-0.2 part of polypeptide, 1-2 parts of nitrogen, phosphor and potassium elements, 2-8 parts of potassium dihydrogen phosphate, 11-13 parts of diammonium hydrogenphosphate, 1-3 parts of calcium dihydrogen phosphate, and 1-2 parts of boric acid. The biological fertilizer possesses the effects of both inorganic and organic fertilizers, relatively effectively radically improves the generation source of soil organic microbes and soil acid-base property, and also is capable of generating active substances, stimulating crop growth and immobilizing nitrogen in air.

Description

Technical field [0001] The invention relates to an agricultural biological fertilizer capable of removing alkali and inhibiting salt. Background technique [0002] The survival of plants depends on the soil as the base, and fertilizer is the food of the plants. Plants need a lot of nutrients to promote their rapid growth during the growth process. Different soils have a certain impact on the growth of crops, which requires effective soil improvement. The existing fertilizers for improving soil can only see the effect of fertilizers on crops, and cannot effectively improve the soil. Most of the soil is hardened due to the application of chemical fertilizers. Due to the unreasonable fertilization of poor soils, there is no effective improvement, resulting in no harvest or under-harvest; especially the saline-alkali land occupies a considerable land area in my country and even countries in the world. Alkali is too heavy to be cultivated, and some have invested a lot of money to imp...

The existing soil-improving fertilizers can only see the impact of fertilizers on crops, and cannot effectively improve the soil

Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially saline-alkali land occupies a considerable area of ​​land in our country and even countries in the world. Alkali is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effect
