Abstract

The invention discloses a desertificated soil improvement method which includes the following steps that (1) desertificated soil needing to be improved is turned over, and a tillage layer is obtained; (2) a desertificated soil amendment is evenly scattered on the surface of the tillage layer, and the desertificated soil amendment and the desertificated soil in the tillage layer are evenly mixed, wherein the desertificated soil amendment comprises, by weight, 2-5% of sodium humate, 20-30% of coal ash, 5-10% of konjaku flour, 20-30% of dried goat manure, 1-3% of guar gum and the balance diatomaceous earth; (3) after the surface of the tillage layer is leveled, the tillage layer is fully watered. According to the method, people only need to turn over the desertificated soil needing to be improved, then the desertificated soil amendment developed according to characteristics of the desertificated soil is added into the tillage layer, the tillage layer is fully watered, and accordingly fertility of the desertificated soil is enhanced, the structure and fertilizer conservation and water retention performance of the desertificated soil are improved, steps are simple, operability is high, cost is low, and the method is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a sandy soil improvement method. Background technique [0002] The large-scale spread of land desertification is desertification, which is one of the most serious global environmental problems. Land desertification leads to the loss of organic matter and fine-grained substances in the soil, coarsening of the soil, decline in fertility, and a serious decline in land productivity. Therefore, finding an economical and effective sandy soil improvement method has important practical significance for maintaining the ecological environment and strengthening economic development. [0003] Now the commonly used method for sandy soil improvement is direct application of organic fertilizer or peat. Direct application of organic fertilizer and peat can only improve the fertility of sandy soil, but cannot improve the structure and water and fertilizer retention of sandy soil, and the...
