Problems solved by technology

[0005] Applying soil improver to saline-alkali land is a means of improving saline-alkali land. The existing soil improvers have the following deficiencies: (1) The ability and effect of reducing soil salinity are limited; (2) Effectively reduce soil pH and Soil alkalinity; (3) cannot effectively improve the water retention, water holding capacity, and water content of the soil; (4) the air permeability of the soil is poor

Abstract

The present invention discloses a halophilic bacteria-containing soil modifier for saline land, wherein the raw materials comprise, by mass, 8-13 parts of fulvic acid, 4-6 parts of emulsified asphalt, 0.2-0.5 part of salicylic acid, 1-3 parts of malic acid, 5-10 parts of hullessbarley residue, 5-10 parts of bentonite, 5-10 parts of a urea-formaldehyde resin, 1-5 parts of stachybotrys atra, 3-7 parts of halomonas halophilic bacteria, 0.5-1.2 parts of halophilic methane bacteria, 4-6 parts of melilotus officinalis l powder, 7-12 parts of puccinelia chinampoensis, and 0.5-0.9 part of a water retention agent. The invention further discloses applications of the modifier in cichorium intybus l planting. According to the present invention, 12 months after the cichorium intybus l is planted, the salt content in the 0-30 cm soil layer is 0.20-0.26%, the water content and the water holding porosity of the soil respectively are 25.4-26.7% and 55.4-56.5%, and the water retention capacity and the aeration porosity of the soil are significantly improved.

Description

technical field [0001] The invention provides a soil improver containing halophage bacteria for saline-alkali land and its application in chicory planting, belonging to the technical field of soil improvement. Background technique [0002] my country is a country with a wide distribution of saline-alkali soil, and the total amount of saline-alkali soil resources is about 9913×10 4 ha, about 920.99×10 in cultivated land 4 ha, with varying degrees of salinization, accounting for 6.62% of the country's cultivated land area. [0003] The problem of soil salinization and secondary salinization has become an unavoidable problem in agricultural production, affecting economic development, threatening the stability of oasis ecosystems, and is the main obstacle restricting agricultural development in arid areas. Reasonable way to solve it. [0004] The water and soil in northern my country are mostly alkaline. In some areas, although gardens and green spaces are built on good land ...
