Abstract

The invention relates to the technical field of saline-alkali land improvement, in particular to a biological improvement method of a secondary saline-alkali land. The method comprises the following steps of: (1) digging a furrow on the surface of a saline-alkali land, wherein the width of the furrow is 20-40 cm and the depth of the furrow is 10-20 cm; (2) uniformly applying an organic fertilizerinto the furrow, wherein the dosage of the organic fertilizer is 450-650 kg per acre; covering soils back after applying the fertilizer, covering the soils with a film, and treating for 1-4 weeks; (3)planting a saline-alkali-resistant herbage hairy vetch on the soils of the saline-alkali land in the first year; (4) planting two-year seedlings of Elaeagnus angustifolia at the first four months ofthe second year, wherein the row spacing of plants is 2.5 m*2.5 m, and the seedlings are intercropped with Suaeda salsa; (5) intercropping a sesame with the Elaeagnus angustifolia after harvesting theSuaeda salsa in the third year. The method can improve the organic content of the secondary saline-alkali land, improve the soil structure, reduce the alkalinity and the salt content of the soils, improve the salt resistance of crops, increase the contents of hydrolyzed nitrogen, quick-acting phosphorus and quick-acting potassium in the soils, and improve the economic benefit of the secondary saline-alkali land.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a biological improvement method for secondary saline-alkali land. Background technique [0002] Saline-alkali land is the general term for all kinds of saline soil, alkaline soil and salinized and alkalized soil. According to the amount of saline-alkali content in the soil, it can generally be divided into three types: mild, moderate and severe saline-alkali land. As an important land resource, soil Salinization has seriously affected the regional ecological environment and food production. According to incomplete statistics from UNESCO and FAO, the global saline-alkali land area reaches 955 million hm 2 , while the total area of ​​saline-alkali land in my country is about 99.14 million hm 2 , ranking third in the world. Saline-alkali soil is mainly characterized by stickiness when wet and poor air permeability; hard when dry and poor water permeability....
