Problems solved by technology

However, the existing microbial fertilizers also have some defects when improving saline-alkali land, as follows: (1) While reducing the salinity of the soil, it cannot increase the air permeability of the soil well; (2) The content of organic matter in the improved soil , the total nitrogen content is still at a low level; (3) After being applied to saline-alkali land, the types and contents of soil microorganisms increased are low; (4) After the improvement of the soil, the survival rate of transplanting plants is not high

Abstract

The invention provides a saline-alkali soil microbial fertilizer comprising, by mass, 35-42 parts of maleic anhydride, 35-40 parts of livestock and poultry manure, 18-22 parts of corn stalk, 12-15 parts of biochemical fulvic acid, 8-11 parts of humic acid, 0.2-0.5 parts of a microbial agent, 7-9 parts of a phosphate fertilizer, 2-4 parts of amino acid salts, 0.1-0.3 parts of boric sludge, and 1-3 parts of manganese mud. The invention also provides a preparation method of the microbial fertilizer and an application of the microbial in rhus typhina planting. With the fertilizer, soil salinity can be reduced to 0.5-0.7%, soil ventilation porosity can be improved to 12-16%, soil organic matter content can be increased to 9.5-10.6g / kg, and soil total nitrogen content can be improved to 0.060-0.08%. With the fertilizer, rhus typhina transplanting survival rate and stress resistance are both substantially improved.

Description

technical field [0001] The invention provides a fertilizer and its application in torch planting, in particular to a saline-alkali land microbial fertilizer and its application in torch planting, belonging to the technical field of soil fertilizers. Background technique [0002] In my country, the scale of saline soil is quite large. Among the 100 million hectares of cultivated land, there are about 5.374 million hectares of saline soil, and another 44.088 million hectares of saline-alkali wasteland are distributed in Northwest, North China, Northeast China and coastal areas. Studying special fertilizers for salt-tolerant crops in saline soil is one of the effective measures to control saline soil, and it is of great significance to adjust and improve the agricultural ecological environment of saline-alkali soil and increase agricultural production, as well as the sustainable development of agricultural and animal husbandry production in saline-alkali areas. [0003] The ap...
