Embodiment 1

[0011] Put 10% water by weight in the reactor, heat to 80°C, then put 10% by weight mixed amino acid and 10% citric acid into the reactor, stir and keep for 0.5 hours. Then, pulverize the copper sulfate with a component weight percentage of 70% to 50 mesh and add it into the reaction kettle, and carry out complexation reaction at 100° C. for 1.5 hours to obtain a complex of organic copper elements for future use. The natural air-dried peat with a water content of 5% is uniformly mixed with zeolite powder, bentonite, attapulgite powder and fly ash according to the ratio of component weight 50:10:20:15:5 to prepare a peat-containing mixture for use. The final product is obtained by compounding the composition weight percentages of 5% organic copper compound, 5% peat-containing mixture, 35% urea, 30% superphosphate and 25% potassium sulfate.

Embodiment 2

[0013] The operating procedure was the same as in Example 1 during preparation. Just have change to the kind of raw material, quantity, thickness and dissolving temperature, reaction time and the water content of peat, silkworm dung, chicken manure, cow dung within the scope that operation program of the present invention stipulates, still prepare the present invention one of the same A special fertilizer for slope artificial soil containing organic copper elements.

Abstract

The invention provides a method for preparing an organic copper element-containing fertilizer special for side slope artificial soil. The fertilizer is prepared by processing the following raw materials under certain conditions: copper sulphate, a hydroxyl polar solvent, a mixture of turf or / and silkworm manure or / and chicken manure or / and cattle manure, a complexing agent, zeolite powder, bentonite, attapulgite powder, coal ash and a fertilizer. The organic copper element-containing fertilizer has obvious functions of improving the effect of the copper element in the side slope artificial soil, preventing and treating physical diseases caused by copper loss, improving the physical characteristics of the side slope artificial soil and accelerating the growth of plants.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing a special fertilizer for slope artificial soil containing organic copper elements. Background technique [0002] my country is a large country with mountains, and mountainous areas account for 69% of the total land area of ​​our country. A large number of exposed slopes formed by the construction of roads, hydropower, and mines in mountainous areas have become a special habitat that has been severely degraded due to the stripping and destruction of the original soil and vegetation cover, resulting in a large number of secondary bare land and serious soil erosion. phenomenon, causing great damage to the ecological environment. Reconstructing artificial soil on exposed slope wounds has become a fundamental measure for slope ecological protection and vegetation restoration. Widely used slope artificial soil is usually made of natural soil, fertilizer, plant fiber, binder, aggr...
