Problems solved by technology

However, due to the lack of targeted and effective special organic iron fertilizers, iron fertilizers purchased on the market for farmland soil are still used in the process of engineering wound soil remediation, resulting in unreasonable fertilizer use, uncoordinated nutrient supply, A series of production problems such as low fertilizer utilization rate lead to inconspicuous effects of soil fertilization and vegetation restoration on engineering wounds

Embodiment 1

[0010] Put the chitosan oligosaccharide with a component weight percentage of 50% into a reaction kettle, add water with a component weight percentage of 50% to dissolve, stir at 80°C for 0.3 hours, and prepare a chitosan oligosaccharide solution for use. Put tartaric acid with a component weight percentage of 26% into the reactor, dissolve it with water with a component weight percentage of 31%, then add triethanolamine with a component weight percentage of 3% for dissolution, and stir at 80°C for 0.2 hours ; Then, adding ferrous sulfate with a weight percentage of 40% to the reactor, and boiling it at 100° C. for 0.5 hour to prepare an organic iron element solution for later use. The final product is obtained by compounding 8% chitosan oligosaccharide solution, 90% organic iron element solution, 1% polysorbate and 1% carboxymethyl cellulose sodium in component weight percentages.

Embodiment 2

[0012] The operating procedure was the same as in Example 1 during preparation. Just change the type, quantity, dissolution temperature, stirring time and boiling time of raw materials within the scope specified by the operating procedures of the present invention, and still prepare a special organic iron fertilizer for engineering wound soil restoration of the present invention in the same way.

Abstract

The invention provides a preparation method of an organic iron fertilizer for engineering wound soil remediation. The organic iron fertilizer is prepared from the following raw materials via effectivemixing under a certain condition: chitin oligoes or / and wormcast or / and silkworm excrement, water or / and hydrogen peroxide, solution with organic iron element, polysorbate and sodium carboxymethyl cellulose. The method has remarkable effect in the aspects of improving the physicochemical properties of engineering wound soil, enhancing the effectiveness of the soil iron elements, preventing physiological diseases caused by iron deficiency of plants and promoting the growth and development of the plants.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a method for preparing an organic iron fertilizer specially used for engineering wound soil restoration. Background technique [0002] With the rapid development of social progress and urban and rural construction, there are more and more engineering construction projects such as roads, railways, mines, water conservancy, and electric power, and the geotechnical engineering construction in the engineering construction process often requires excavation of slopes and damaged ground surfaces, resulting in The number of engineering wounds is increasing year by year. Large-scale engineering wounds not only destroy the original soil vegetation cover and natural landscape, but also cause serious water and soil erosion, geological disasters, and ecological damage. For engineering wounds with very special habitats, the soil remediation measures of stacking soil on engineering wounds in a specific way and ...
