Saline-alkali soil microorganism bacterial manure and application thereof in red fescue planting

Abstract

The invention discloses saline-alkali soil microorganism bacterial manure. The saline-alkali soil microorganism bacterial manure comprises, by mass, 4-9 parts of corncobs, 5-10 parts of sweet potato residues, 13-16 parts of fulvic acid, 10-14 parts of desulfurated waste, 5-7 parts of charcoal, 12-18 parts of vinyl acetate and dibutyl maleate copolymers, 6-8 parts of polyethylene glycol, 2-6 parts of microalgae powder, 4-9 parts of red prince weigela powder, 2-5 parts of exiguobacterium aurantiacum, 3-5 parts of halobacterium salinarium and 0.6-0.9 part of water-retaining agent. The invention further discloses application of the saline-alkali soil microorganism bacterial manure in red fescue planting. The saline-alkali soil microorganism bacterial manure has the advantages that after 12 months when red fescue is planted, the salt content of a soil layer of 0-30 cm is 0.21-0.29%, the pH of the soil is 6.8-7.2, the total nitrogen content in the soil is 0.125-0.154%, the number of ventilation holes in the soil is increased, and the water content of the oil is increased.

Description

technical field [0001] The invention provides a saline-alkali land microbial fertilizer and its application in planting purple fescue multiflora, belonging to the technical field of soil improvement. 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. It is to improve saline-alkali land by planting plants in saline-alkali land. The method is easy to implement and has significant economic benefits. However, it is generally necessary to plant saline-alkali-tolerant plants to restore the soil through the salt-absorbing ability of the plants themselves; using microbial fertilizers to improve saline-alkali land is also a biological im...

AI Technical Summary

Problems solved by technology

[0003] The application of microbial fertilizer in improving saline-alkali land, as a means of biological improvement, has been increasingly valued by people, but there are also shortcomings: (1) the degree of reducing the pH value and salinity of the soil is insufficient, and it takes a long time; (2 ) The content of nutrient elements in the soil has not been effectively improved; (3) The effect of improving the air permeability and water holding capacity of the soil is limited; (4) The mechanical stability of 5-7mm water-stable aggregates in the soil is not high; (5) The existing technology After improving the soil, planting salt-intolerant pasture grass, the pasture yield is not high
