Embodiment 1

[0035] A method for planting wheat on saline-alkali land, comprising the following steps:

[0036] (1) Composting: Grinding phosphogypsum into 100 mesh fine powder, after mixing the obtained phosphogypsum powder with organic fertilizer, the weight ratio of the phosphogypsum powder and organic fertilizer is 20:100, and the organic matter content in the organic fertilizer is 52%, adjust the moisture content of the mixed material to be 40%, then stack and seal with yellow mud for 80 days to obtain compost;

[0037] (2) Primary treatment of saline-alkali land: First, crush phosphogypsum into 100-mesh fine powder, and then adjust the water content in saline-alkali land to 40%. The content is 0.16%, and the pH value is 8.1. Apply phosphogypsum powder evenly on the surface of saline-alkali land. The application rate of phosphogypsum powder is 350kg / mu, and then carry out rotary tillage treatment. Take it away and carry out leaching treatment;

[0038] (3) Secondary treatment in sal...

Abstract

The invention discloses a method for planting wheat on saline and alkaline land. The method includes the steps of firstly, evenly applying ardealite powder to the surface of the saline and alkaline land, and then conducting rotary tillage; secondly, taking a thin film and conducting leaching after the land is covered with the film for a period of time, and then evenly applying field ficus tikoua bur stem pieces in the saline and alkaline land, and conducting rotary tillage; thirdly, evenly applying compost, mushroom residues and oil cakes in the saline and alkaline land, and finally planting wheat. According to the method, the saline and alkaline land is improved through three steps, the salt content in the saline and alkaline land can be effectively decreased, and therefore the saline and alkaline land can be used for planting wheat, high and stable yield of wheat can be achieved, and remarkable economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of improving saline-alkali land, in particular to a method for planting wheat on saline-alkali land. Background technique [0002] Saline-alkali land is the general term for salt land and alkaline land. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, and the soil is alkaline. The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops, so it is difficult for crops to promote seedlings. The area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline land and alkalized soil in my country is mostly relate...
