Problems solved by technology

[0003] The application of microbial fertilizer in improving saline-alkali land, as a means of biological improvement, has attracted increasing attention. This method can improve fertilizer utilization and reduce the alkalinity of saline-alkali land, but there are also shortcomings: (1) preparation and storage of improvers The activity of microbial flora will be lost during transportation and transportation; (2) The effect of improving soil moisture content, soil total porosity and soil water seepage rate is not ideal, and the improvement degree of soil physical structure is not high, and the structure is not good. Stable; (3) After improvement, planting plants, the survival rate is not high, and the quality is not good

Abstract

A microbial fertilizer for saline-alkali land is provided. The microbial fertilizer comprises following components by mass: 30-40 parts of maleic anhydride, 30-40 parts of livestock manure, 20-25 parts of corn straw, 12-14 parts of biochemical fulvic acid, 8-10 parts of humic acid, 0.2-0.3 part of a microbial agent, 7-8 parts of a phosphorus fertilizer, 2-5 parts of amino acid salts, 0.1-0.4 part of boric sludge and 2-3 parts of manganese ore sludge. Applications of the microbial fertilizer in plantation of vitex rotundifolia are also provided. The beneficial effects of the microbial fertilizer and the applications are that the soil salt content is reduced to 2.0-2.5%, the water content of the soil is increased to 24-26%, the total porosity of the soil is increased to 45-56%, the water seepage speed of the soil is increased by 42-53%, and the survival rate of transplanting of the vitex rotundifolia is 96.1-97.8%.

Description

technical field [0001] The invention provides a fertilizer and its application in the planting of Vitex simplex, in particular to a microbial fertilizer in saline-alkali land and its application in the planting of Vitex simplex, belonging to the technical field of soil fertilizers. Background technique [0002] Improvement methods for saline-alkali land include physical improvement, chemical improvement, and biological improvement. Physical improvement is generally costly, and chemical improvement is likely to cause chemical component residues. Therefore, biological improvement has become the mainstream of the market. Traditional biological measures improve saline-alkaline land. Improving saline-alkali land with plants is easy to implement and has significant economic benefits. Biological measures can gradually change the physical characteristics of the soil, change the soil structure, make the texture loose, and enhance the air permeability and water storage capacity.
