Abstract

The invention discloses a saline-alkaline soil conditioner. The saline-alkaline soil conditioner comprises, by mass, 30-55% of a red bayberry juice, 10-25% of calcium nitrate, 5-15% of fulvic acid, 1-3% of composite microelement fertilizer, 0.5-2% of rooting powder and the balance water. The multifunctional saline-alkaline soil conditioner with pH less than 7 can neutralize alkaline soil, contains active groups and natural organic material special function groups for reducing soil harmful ion-caused soil and plant damage through adsorption and exchange, and realizes saline-alkaline soil improvement through synergism of all ingredients. Compared with the traditional saline-alkaline soil conditioner, the saline-alkaline soil conditioner provided by the invention has the characteristics of multiple functions, environmental friendliness, low price and production and use convenience.

Description

technical field [0001] The invention belongs to soil conditioning agents, in particular to a conditioning agent for rapid desalination of tidal flat saline-alkali soil. Background technique [0002] Nearly 10% of the world's land is covered by different types of saline-alkali soil, mostly in arid and semi-arid areas. About half of the world's existing irrigated lands are threatened by secondary salinization; in my country's northeast, north and northwest regions, there are different types of saline-alkali lands. At the same time, various coastal saline soils (such as coastal tidal flats) are widely distributed in coastal areas land), this kind of soil itself lacks maturation, the soil quality is poor, there are double obstacles of salinization and poor soil quality, there are too many water-soluble ions harmful to crops, crops are not easy to emerge, and the growth and development of general salt-alkali-tolerant plants are affected. Severely inhibited. [0003] The river coa...
