Saline-alkali soil improving method

Abstract

The invention discloses a saline-alkali soil improving method. The saline-alkali soil improving method comprises the following steps of A, deep-ploughing and levelling saline-alkali soil; B, performing buried pipe salt removal on the leveled soil; C, after buried pipes are laid to irrigate the saline-alkali soil; D, applying soil targeted conditioning agent to the processed saline-alkali soil; E,planting saline-alkali tolerant rice. The saline-alkali soil improving method sets a wireless transmission mode inside a planting area to achieve remote rice growth monitoring, can significantly improve the physical structure of the saline-alkali soil, reduce the total salt content of the saline-alkali soil, activate soil, preserve water and fertilizer, increase the organic content of the soil, improve the physicochemical properties of the saline-alkali soil and further achieve long-term virtuous cycle of the saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a method for improving saline-alkali land using a four-dimensional improvement method. Background technique [0002] Saline-alkali land contains more water-soluble salts or alkaline substances, high salinity, high alkalinity, loss of soil humus, and damage to the soil structure. It is sticky when wet and hard when dry. Poor water permeability makes it difficult for plants to grow here. Therefore, improving saline-alkali land is a very meaningful work. [0003] At present, domestic methods for improving saline-alkaline land include, firstly, developing plants that are resistant to saline-alkali and using plants to improve and repair the soil; and secondly, improving the physical and chemical properties of the soil. There is also the method of rinsing to reduce the salt and alkali content. [0004] The use of plants for soil improvement has high requirements on the tole...
