Abstract

The invention discloses a method for improving a saline and alkaline land by utilizing alfalfa-beet-cotton-maize rotation. By the method, the saline and alkaline land is improved by ditching and draining, pressing salt into fresh water, adding improved fertilizer or compound fertilizer, performing ploughing and rotary tillage, planting alfalfa, beet, cotton and maize year by year and returning straws. The method has prominent improvement effect on the whole saline and alkaline land, and the improvement process is environment-friendly and pollution-free. Therefore, the method is an applicationtechnology worthy of large-area popularization.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, and in particular relates to a method for improving saline-alkali land by utilizing alfalfa-beet-cotton-corn crop rotation. Background technique [0002] At present, there are mainly the following technical measures for the transformation of saline-alkali land: [0003] 1. Water conservancy improvement, salt washing with fresh water: suitable for well-drained areas with high terrain. [0004] 2. Biological improvement: improve the micro-ecological environment of saline-alkali land, apply bio-organic fertilizers, supplement organic matter, and increase the number of beneficial microorganisms in the soil, so as to establish a new micro-ecological balance between soil, plants and microorganisms in saline-alkali land, and achieve the goal of biological control. [0005] 3. Chemical improvement: apply about 15 tons of gypsum per hectare, and apply it once as a base fertilizer. ...
