Abstract

The invention discloses an economical and quick method for planting salinized soil lawn, and relates to the field of the treatment of salinized soil. The method comprises the following steps of: (1) tidying the salinized soil; (2) building a drainage canal; (3) applying organic fertilizer, silver sand and base fertilizer; (4) building ridges, and desalting in an elution way; (5) selecting the grass variety; (6) building and planting a grass blanket; (7) transplanting the grass blanket; and (8) managing the cultivation. According to the method, the structure of the salinized soil can be effectively improved, the naked surface of the salinized soil can be covered, the evaporation of water on the surface of the ground can be reduced, and the salt content of surface soil can be reduced; the method is low in planting cost, the salinized soil can be comprehensively used in large area, and the structure of the plant of the salinized soil can be adjusted; and the plant cover area of the salinized soil can be enlarged, and the ecological environment can be protected and improved.

Description

technical field [0001] The invention relates to the field of saline soil treatment, in particular to an economical and rapid saline soil lawn planting method. Background technique [0002] The total area of ​​saline soil in my country is 99.13 million hm 2 (It is an area unit, which means hectare, that is, 10,000 square meters, which is generally used for the calculation of land area.), mainly distributed in 5 large regions, namely the arid saline-alkali soil area in Northeast China, the saline-alkali soil area in North China, and the semi-arid saline-alkali soil area in Northwest China , Northwest arid saline-alkali soil area and coastal saline-alkali soil area. Because there is a large amount of salt in the saline soil, the alkalinity is too high and the soil properties are poor, which has caused great difficulties in urban greening and environmental governance in these areas. Grass review, as an important part of environmental greening, can not only green, beautify the ...
