Method for improving farmland soil fertility by inorganic mineral activation material

A technology that stimulates materials and inorganic minerals. It is applied in the direction of soil preparation methods, organic fertilizers, and soil conditioning materials. It can solve the problems of little soil improvement and soil fertility improvement, and it is difficult to use, so as to avoid dust scattering, facilitate mechanical application, and increase adsorption. surface effect

Problems solved by technology

In recent years, rock wool has been used as a commonly used building insulation material. A large amount of waste rock wool is produced in my country every year. In the process of industrial production, a large amount of rock wool scraps are produced, which can only be discarded and difficult to use.
In the field of agricultural production, rock wool has been used as a substrate for soilless cultivation of vegetables and flowers, but it is rarely used for soil improvement and soil fertility improvement.

Embodiment 1

[0034] Select the Agroecological Experimental Station of Fengqiu Agricultural Ecology, Nanjing Soil Research Institute, Chinese Academy of Sciences as the test soil, adopt the potted plant mode, and plant crops as wheat and corn. Three treatments were set up in the experiment, which were conventional fertilization treatment (CK1, application of nitrogen fertilizer 210kg / ha, phosphate fertilizer 105kg / ha, potassium fertilizer 105kg / ha), conventional fertilization + 1% rock wool improver treatment (1% Rock wool, equivalent to 20t / ha), conventional fertilization + 3% rock wool improver treatment (3% rock wool, equivalent to 60t / ha), the cultivation test set up 6 treatments, respectively conventional fertilization Treatment (CK2, nitrogen fertilizer 210kg / ha, phosphate fertilizer 105kg / ha, potassium fertilizer 105kg / ha), conventional fertilization + 1% of soil dry basis weight rock wool improver treatment (rock wool), conventional fertilization + straw treatment (straw) , Conventi...

Abstract

A method for improving farmland soil fertility by an inorganic mineral activation material includes steps: taking basalt, dolomite and slag as raw materials and coke as a fuel, heating to 1600 DEG C to melt, adopting a centrifuge for fiber forming treatment to obtain a rock wool fiber material in a diameter range of 4-10micron, and performing loose granulation; mixing the rock wool fiber materialinto a farmland soil plough layer, wherein rock wool applying quantity is 18-22t/ha; applying a natural plant organic material; conventionally fertilizing, ploughing, and adjusting soil moisture untilfield moisture capacity reaches 65-75%, so that rock wool fiber particles are dispersed in a fiber form in soil under moisture absorption swelling and external ploughing action. The method has advantages that recycling of rock wool leftover materials can be realized, and low cost, simplicity, high efficiency and quickness in soil fertility improvement are realized.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for improving farmland soil fertility by using inorganic mineral excitation materials. Background technique [0002] Rock wool is a fibrous mineral, made of basalt as the main raw material, dolomite and slag as auxiliary materials, and coke as fuel, which is melted and drawn in a high-temperature furnace at 1500-2000 °C. Because rock wool has many advantages such as chemical stability, sterility, high porosity, strong water retention performance and low price. In recent years, rock wool has been used as a commonly used building insulation material. A large amount of waste rock wool is produced in my country every year. In the process of industrial production, a large amount of rock wool scraps are produced, which can only be discarded and difficult to use. In the field of agricultural production, rock wool has been used as a substrate for soilless c...
