Abstract

The invention discloses an improvement method of soil ecological depth in a moderate saline-alkali land. The improvement method comprises the steps that one, area surface sundries and weeds of the saline-alkali land to be improved are cleared; two, composite biological ameliorant is spread on the surface of the saline-alkali land to be improved and mixed with sand, carbide slag and potassium humate, a large quantity of soil beneficial microorganisms are bred in the short term, and soil activity is rapidly activated; three, the saline-alkali land to be improved is subjected to ploughing, leveling, irrigation, and film covering, then heat preservation and humidification for 10-15 days, acid-base balance is regulated while the soil salinity and alkali content is reduced, so that the microorganisms are over propagated and suffocated to death, and a sterile soil environment is created; four, membrane is removed and soil is air-dried, fermented organic fertilizer is applied, then salt-tolerant plants are sown to improve the biological depth of soil; five, when the growth of the sown salt-tolerant plants reaches the maximum, the salt-tolerant plants are removed and moderate saline-alkalisoil improvement is completed. The method is low in improvement cost, good in effect, and ecological and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land management, and in particular relates to a soil ecological depth improvement method for moderate saline-alkali land. Background technique [0002] Various coastal saline soils are widely distributed in coastal areas. This kind of soil itself lacks maturation, and the soil quality is poor. There are double obstacles of salinization and poor soil quality. The growth and development of saline-alkali plants will be inhibited. [0003] However, this kind of soil has favorable conditions such as deep soil layer, flat terrain, and suitable for mechanical farming. However, due to the existence of excessive salt and strong alkalinity, the crop yield is low or even completely eliminated, forming a large area of ​​saline-alkaline wasteland. The ecological environment is bad. With the dwindling of available arable land resources, saline-alkali land is a precious reserve soil resource, and its dev...
