Problems solved by technology

In the past, there were also researches on various types of microbial saline-alkali soil amendments aimed at the problem of widespread distribution of saline-alkali land in my country and the lack of effective governance. It is well adapted to the saline-alkali habitat of the arid desert, let alone improving the saline-alkali land and improving the viability of plants

Abstract

The invention discloses water-holding root-promoting halophilic alkaliphilic microorganism root dipping liquid and preparation and application thereof. The water-holding root-promoting halophilic alkaliphilic microorganism root dipping liquid comprises, by weight, 1 part of halophilic alkaliphilic microorganism solid bacterial manure of desert halophilic alkaliphilic habitat, 1 part of sterilization soil, 2 parts of water, 0.1 part of water-holding agent and 0.002-0.005 part of growth hormone. The bacterial manure comprises, by weight, 100 parts of fermentation materials, 1-3 parts of sulphur powder, 0.5-1.5 parts of zinc sulfate and 0.5-1.5 parts of magnesium sulfate, and moisture content<=20%. The invention further discloses the preparation method for the water-holding root-promoting halophilic alkaliphilic microorganism root dipping liquid. The water-holding root-promoting halophilic alkaliphilic microorganism root dipping liquid contains a large amount of halophilic alkaliphilic microorganisms and can enable nursery stock roots to adapt to saline alkaline soil easily.

Description

technical field [0001] The invention relates to the field of biological bacterial fertilizer technology and saline-alkali land treatment, in particular to a root-dipping solution for water-retaining and root-promoting halophilic microorganisms, a preparation method and application thereof. Background technique [0002] Halo-alkali bacteria have survived and evolved in saline-alkali environment for a long time, forming some very special structures and physiological mechanisms, and can produce some unique metabolites. The related enzymes and special biologically active substances produced by it have important industrial value and have made great contributions to human beings. In the arid oasis area of ​​Northwest my country, saline-alkali land and saline-alkali flats account for 40% of the total land area. The groundwater level in this area is high, the soil is saline-alkali heavy and saline-alkali land is widely distributed. Rich resources of halophilic bacteria. [0003] Th...
