Water-saving, fertilizer-saving and soil-moisture-preserving treatment method for cultivated land in yellow flood area

Abstract

The invention discloses a water-saving, fertilizer-saving and soil-moisture-preserving treatment method for cultivated land in a yellow flood area. The core technology is a method for forming a water-resisting layer in a cultivated land layer, additional materials for forming the water-resisting layer comprise 150-300 parts of clay, 5-30 parts of urease, 20-80 parts of urea, 10-90 parts of calcium salt and 500-1000 parts of water, the additional materials and undisturbed soil are mixed through a stirrer to form the water-resisting layer, and the water-saving, fertilizer-saving and soil moisture conservation treatment of the cultivated land in the yellow flood area is realized. Water and fertilizer saving and efficient salt control of the cultivated land are achieved through the water-resisting layer, evaporation and loss of underground water are effectively prevented, the relation between underground water salt and soil of the cultivated land layer is cut off, accumulation of salt in the cultivated land layer is avoided, good conditions are created for crop growth, and the purpose of continuously improving the cultivated land is achieved.

Description

technical field [0001] The invention belongs to the technical field of land management and agricultural utilization, and relates to a treatment method for water-saving, fertilizer-saving and soil-moisture conservation of cultivated land in the yellow flood zone. Background technique [0002] The soil layer in the lower reaches of the Yellow River is characterized by layered distribution. The soil quality is mainly silt and silt, with a large permeability coefficient and strong capillary action. The underground silt and silt layer is like an underground desert, which is not conducive to water retention and causes The loss of water and fertilizer in the top cultivation layer causes the cultivated land in this area to be prone to drought, salinization, poor soil quality, low fertility and the disadvantages of groundwater pollution. Difficult to guarantee. Therefore, according to the actual conditions of the soil layer and cultivated land in the lower reaches of the Yellow Rive...

AI Technical Summary

Problems solved by technology

[0004] In view of the poor water retention of the cultivated land in the lower reaches of the Yellow River, it is prone to drought, the amount of irrigation water is large, the loss of fertilizer is serious, the salinization of the soil is obvious, the technical methods of water conservation and fertilizer saving are backward, the cost of cultivation is high, the process of soil fertility cultivation is slow, and the efficiency of water resource utilization is low. A series of practical problems such as the lag of sustainable development, and a set of management methods suitable for saving water, fertilizer and moisture in cultivated land in the yellow flood zone
