Pasty microbial fertilizer for planting plants on alkaline loess abrupt slope and use method thereof

Abstract

The invention relates to the field of protection of ecological environment and is suitable for an agricultural industry and a forestry industry. Plants are planted on an alkaline loess abrupt slope to afforest the alkaline loess abrupt slope. A pasty microbial fertilizer for planting plants on the alkaline loess abrupt slope is mainly characterized by comprising the following components in percentage by weight: 0.05-0.08 percent of Azotobacter chroococcum liquid, 0.03-0.05 percent of Bacillus mucilaginosus liquid, 0.02-0.04 percent of Bacillus megaterium, 0.01-0.03 percent of brown sugar, 10-20 percent of domestic sludge, 40-60 percent of water, 0.1-0.3 percent of ferrous sulphate, 3-8 percent of cow dropping, 5-10 percent of wheat straw, 0.01-0.8 percent of water-retaining agent, 1-3 percent of bone meal, 2-5 percent of wood fiber, 0.1-0.5 percent of humic acid, 15-25 percent of countryside soil, 0.01-0.05 percent of ternary compound fertilizer, 0.2-0.5 percent of anhydrous calcium sulfate and 0.002-0.006 percent of alkali resistant plant seed, wherein the Azotobacter chroococcum has the CGMCC (China General Microbiological Culture Collection) No. 3768; the Bacillus mucilaginosushas the CGMCC No. 3769; and the Bacillus megaterium has the CGMCC No. 3770.

Description

Technical field: [0001] The invention relates to the field of ecological environment protection, is suitable for agricultural industry and forestry industry, and particularly relates to planting plants on steep alkaline loess slopes and greening alkaline loess steep slopes. The invention provides a paste microbial fertilizer and its preparation method and application method for planting plants on the alkaline loess steep slope. Background technique: [0002] At present, most of the treatment of alkaline loess steep slopes in the world adopts the water conservancy improvement method to establish an irrigation system to discharge alkali; the chemical improvement method uses acidic materials to neutralize the acid and alkali in alkaline land; Excavate the alkaline soil in the alkaline soil and backfill the fine soil; the sand pressure improvement method, add a large amount of fine sand to the alkaline soil to prevent the alkali from returning; the pipeline alkali drainage metho...

Problems solved by technology

There are certain defects and problems in the above methods. First, it consumes a lot of labor and a lot of materials, and the treatment effect is not long-term, and the treatment effect is not ideal.

The governance cycle is relatively long and the speed is slow. The governance is limited by objective conditions, resources and raw materials, water resources, and drainage conditions, and the cost of governance is very high.
