Abstract

The invention provides an ecological planting and raising method for rapidly desalting saline-alkaline soil of a coastal tidal flat. The method comprises the steps of planting saline-alkaline-tolerant forage grass on the saline-alkaline soil of the coastal tidal flat, harvesting the forage grass for feeding domestic animals, and returning manure generated from the domestic animals to fields as an organic fertilizer. The structure of vegetation of saline-alkaline land is adjusted through planting the saline-alkaline-tolerant forage grass, saline matter ions in the soil are absorbed and transferred by using physiological functions and roots of the forage grass, high-quality forage grass is harvested for feeding the domestic animals such as cattle and sheep, livestock-and-poultry manure generated from domestic-animal raising is prepared into the organic fertilizer, and the organic fertilizer returns to the fields and then can play roles in amending and fertilizing the saline-alkaline soil.

Description

technical field [0001] The invention relates to an ecological cycle planting and breeding method, in particular to a method for rapidly desalinating saline-alkali soil by combining planting and breeding. Background technique [0002] Nearly 10% of the world's land is covered by different types of saline-alkali soil, most of which are distributed in arid and semi-arid areas. About half of the world's existing irrigated land is threatened by secondary salinization. Different types of saline-alkali soils are distributed in Northeast my country, North China and Northwest China. The total area of ​​saline-alkali soil in my country is 99.13 million hectares. At the same time, various coastal saline soils (such as coastal tidal flats) are widely distributed in coastal areas. This type of soil itself lacks maturity. , The soil quality is poor, there are double obstacles of salinization and poor soil quality, too many water-soluble ions that are harmful to crops, crops are not easy to...
