Embodiment 1

[0011] 10% humic acid and 10% oak extract by weight of the component are put into the reactor, and 20% water of the component by weight is added, reacted for 1.5 hours at 80° C., and then the weight of the component is Add zinc sulfate with a percentage of 60% into the reaction kettle, and carry out complexation reaction at 80° C. for 1.5 hours to obtain a complex of organic zinc elements for use. The natural air-dried peat with a water content of 5% is uniformly mixed with industrial attapulgite powder, industrial zeolite powder, industrial bentonite, and agricultural plant ash according to the ratio of component weight 30:30:25:13:2 to prepare The peat mixture is set aside. Finally, the final product is obtained by compounding the composition weight percentages of 8% organozinc element compound, 7% peat-containing mixture, 35% urea, 20% superphosphate, and 30% potassium sulfate .

Embodiment 2

[0013] The operating procedure was the same as in Example 1 during preparation. Only the type, quantity and dissolution temperature of raw materials, the reaction time and the water content of peat, algae residue, silkworm manure and cow manure are changed within the scope specified by the operation procedure of the present invention, and a kind of containing Special fertilizer for slope artificial soil with organic zinc element.

Abstract

The invention provides a method for preparing an organic zinc element-containing fertilizer special for slope artificial soil. The fertilizer is prepared from zinc sulfate, a complexing agent, a catalytic auxiliary agent, mixture containing peat, algal residue, silkworm excrements or / and cow dropping, attapulgite powder, zeolite powder, bentonite, plant ash and a fertilizer serving as raw material components under certain conditions. The fertilizer has the obvious effect of enhancing the effectiveness of the zinc element of the slope artificial soil, preventing and controlling physiological diseases caused to plants by the shortage of the zinc, improving the physical and chemical properties of the slope artificial soil and promoting the growth and development of the plants.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a preparation method of a special fertilizer for slope artificial soil containing organic zinc 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, aggre...
