Ploughing modifier

Abstract

The invention discloses a cultivated land improver, and relates to the technical field of land treatment and agricultural utilization. The cultivated land improver is prepared from the following components in parts by weight: 150 to 300 parts of clay, 20 to 40 parts of modified humic acid, 10 to 30 parts of bacterial liquid, 20 to 80 parts of urea, 10 to 90 parts of calcium salt and 500 to 1000 parts of water. The cultivated land improver prepared by the invention can improve the soil structure while improving the physicochemical properties of saline alkali soil, and has a better comprehensive improvement effect. The soil texture can be improved, the fertilizer utilization rate is increased, and the fertilizer input is reduced; the plant chlorophyll content is promoted, photosynthesis is enhanced, robust growth of crops is facilitated, and both production and income are increased.

Description

technical field [0001] The invention belongs to the technical field of land management and agricultural utilization, and particularly relates to a cultivated land improver. Background technique [0002] Historically, the flooding of the Yellow River caused the soil layer in the lower reaches of the Yellow River to have a layered distribution. The soil is dominated by silt and silt, with a large permeability coefficient and strong capillary action. The underground silt and silt layer is like an underground desert. It is conducive to water retention, but also causes the loss of water and fertilizers in the top cultivation layer, resulting in the characteristics of arable land in the area prone to drought, salinization, poor soil quality and low fertility, and weak water, fertilizer and soil retention capabilities, which in turn makes the crop yield in this area. Hard to guarantee. Therefore, according to the actual situation of soil layers and cultivated land in the lower rea...

Problems solved by technology

[0003] Soil improvement is a new type of agricultural technology. It uses the relevant principles of plant physiology, plant nutrition, plant ecology and chemistry to improve the soil microenvironment and promote the root system of crops. At the same time, appropriate active substances are added to the soil solution to promote the carbon metabolism and nitrogen metabolism of crop growth, so as to achieve the purpose of increasing crop production; currently, most soil improvers on the market are fly ash, sludge, and chemical improvers Most of the single improvers with the core as the core, the improvement effect is not obvious, the comprehensive improvement effect is not good, it is difficult to restore the natural benignity of the land, and achieve the purpose of increasing production and income
