Method for greening original soil of slight alkaline land through water-retaining agent containing cellulose degradation bacteria

Abstract

The present invention provides a method for afforesting original soil on mildly saline-alkali land with a water-retaining agent containing cellulose-degrading bacteria. The water-retaining agent includes leaf powder, white decay bacteria, cellulose-degrading bacteria, buckwheat straw powder, rice husk powder, Enteromorpha powder, japonica powder; the preparation method includes the processing of leaf powder, and the processing of the leaf powder includes the step of preparing a leaf powder product; the present invention also provides the application of the above-mentioned water-retaining agent in the planting of metasequoia in saline-alkali land. Beneficial effects of the present invention: the water retaining agent prepared by the present invention has strong water absorption capacity in distilled water, rain water, and 0.6% NaCl solution, the water absorption capacity in distilled water can reach 940-1250 times of its own weight, and the water absorption capacity in rain water can reach its own weight 700-910 times of its own weight, and its water absorption capacity in 0.6% NaCl solution can reach 390-540 times of its own weight.

Description

technical field [0001] The invention relates to a method for greening original soil of mild saline-alkali land with a water-retaining agent containing cellulose-degrading bacteria, which belongs to the technical field of landscaping. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, it is not easy to store water, and the anion and cation harmful to crops Many, crops are not easy to promote seedlings. [0003] Cellulose Degrading Bacteria Bacteria that break down cellulose. Due to the action of cellulase and the like, cellulose is ...
