Problems solved by technology

Although this method combines the advantages of the two methods, natural organic fertilizers may not be suitable for the growth and reproduction of functional microorganisms, because only when the functional strains reproduce to a certain extent and reach the dominant population can they repair the soil, and some Some natural fertilizers have not been fully decomposed, and many pathogenic microorganisms are mixed in them, which is unfavorable to the colonization and growth of plants after soil remediation

Abstract

The invention relates to a bio-organic fertilizer for improving the soil quality of saline-alkali soil and application thereof. The bio-organic fertilizer comprises a decomposed protein bio-organic fertilizer and microbial functional composite bacterial powder, wherein the microbial functional compound bacterium powder is a mixture of bacillus subtilis bacterium powder and bacillus licheniformis bacterium powder, and the mass ratio of the decomposed protein bio-organic fertilizer to the microbial functional composite bacterial powder is (30-100): (1-3). After the bio-organic fertilizer is added, the growth condition of vegetation and the physical and chemical properties (pH, nitrogen, phosphorus and potassium nutrient content and organic matter) of soil are obviously improved, and the improvement effect of the decomposed protein bio-organic fertilizer and the microbial functional composite bacterial powder on the saline-alkali soil is fully demonstrated.

Description

technical field [0001] The invention belongs to the field of microbial bacterial agent products, and in particular relates to a bio-organic fertilizer for improving the soil quality of saline-alkali land and its application. Background technique [0002] In my country, the total area of ​​saline-alkali soil is about 99.13 million hectares, and the area of ​​saline-alkali soil in Tianjin is 783,000 hectares, accounting for 65.7% of the total area. The area of ​​saline-alkali soil in Binhai New Area is 195,900 hectares, accounting for 86.3% of the total land area of ​​Binhai. Under the background of shortage of land resources and increasingly urgent ecological environment construction in our country, saline-alkali land has become a valuable land resource. However, most crops and landscaping plants cannot survive in heavy saline-alkaline areas, which seriously restricts the development of agriculture and forestry and the construction of urban ecological landscapes. How to con...
