Embodiment 1

[0011] 5% humic acid and 10% rubber extract by weight of the components are put into the reactor, and 30% water by weight of the components is added, and reacted for 1.5 hours at 80° C., then the weight of the components Add ferrous sulfate with a percentage of 55% into the reaction kettle, and perform complexation reaction at 90° C. for 1 hour to obtain a complex of organic iron elements for use. Naturally air-dried peat with a water content of 5%, and industrial attapulgite powder, industrial zeolite powder, industrial bentonite, industrial diatomaceous earth powder, and agricultural plant ash by component weight 28:50:5:10:5 : 2 and mixed evenly to prepare the peat-containing mixture for subsequent use. Finally, the final product is obtained by compounding the composition weight percentages of 5% organic iron element compound, 10% peat-containing mixture, 30% urea, 30% superphosphate, and 25% 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 iron element.

Abstract

The invention provides a method for preparing special fertilizer containing organic iron element for artificial slope soil. The fertilizer is prepared by processing the following raw materials of ferrous sulfate, complexing agent, catalytic promoter, mixture containing peat or / and algal residue or / and silkworm excreta or / and dairy manure, attapulgite powder, zeolite powder, bentonite, diatomite powder, plant ash and chemical fertilizer under certain condition. The fertilizer has obvious effects on strengthening the effectivity of artificial side slope soil iron element, controlling the physiological disease caused by plant iron deficiency, improving the physicochemical characteristic of artificial side slope soil, and promoting the growth and development of 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 iron 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...
