A kind of farmland improvement material and using method

Abstract

The invention provides a raw material for farmland transformation and its use method. The invention makes full use of the physical and chemical characteristics of the raw material, adopts the material that can be obtained locally and the waste silica fume in the metal silicon smelting industry as the raw material, and the material construction technology is convenient and convenient. Applied to farmland improvement activities, it provides a material and method for effectively reducing or avoiding water seepage and leakage in the stone layer, and carrying out structural transformation on the stone layer. Significant reduction or even avoidance, not only achieves the purpose of improving soil moisture conservation capacity, but also realizes the purpose of transforming dry fields that cannot be cultivated into paddy fields due to water seepage and leakage in the lower pebble layer of cultivated fields, and has the advantages of easy-to-obtain, economical and cheap raw materials .

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a material for farmland transformation and a use method. Background technique [0002] Under the cultivated soil layer in the Yellow-Huai River Basin in China, most of the calculus layer structure is mainly composed of calcium carbonate. This kind of permeable calculus layer makes the fields can only be cultivated in dry fields. It has been accumulated throughout the ages to prevent the evaporation of soil surface water and Moisture-conserving agricultural technology farming to prevent soil leakage is still unable to carry out paddy field farming on such a structured field. Due to the limitation of being unable to effectively reduce or avoid water seepage and leakage in the rock layer under the cultivated soil layer, it is often necessary to carry out agricultural activities such as drought resistance. Therefore, if the theory and technology in the field of materials can be a...

[0002] Under the cultivated soil layer in the Yellow-Huai River Basin in China, most of the calculus layer structure is mainly composed of calcium carbonate. This kind of permeable calculus layer makes the fields can only be cultivated in dry fields. It has been accumulated throughout the ages to prevent the evaporation of soil surface water and Moisture-conserving agricultural technology farming to prevent soil leakage is still unable to carry out paddy field farming on such a structured field. Due to the limitation of being unable to effectively reduce or avoid water seepage and leakage in the rock layer under the cultivated soil layer, it is often necessary to carry out agricultural activities such as drought resistance. Therefore, if the theory and technology in the field of materials can be applied to this, a material and method for structural transformation of the gravel layer can be invented, which can effectively reduce or avoid the phenomenon of water seepage and leakage in the gravel layer, which will not only improve the soil moisture conservation capacity, but also It can transform dry fields that cannot be used for paddy field cultivation due to water seepage and leakage under the soil into paddy fields, which has positive significance for increasing agricultural production, income, and economic benefits
