Abstract

The invention provides a saline-alkali soil improving matrix and a preparation method thereof. The improving matrix is prepared from, by weight, 80-100 parts of wood processing waste, 40-50 parts of duck manure, 2-5 parts of monoammonium phosphate, 25-35 parts of calcium phosphate, 15-25 parts of flue gas desulfurization gypsum, 20-30 parts of vermiculite, 10-20 parts of perlite, 30-40 parts of furnace ash and slag, 120-130 parts of hydrolytic polymaleic anhydride and 1-2 parts of yeast. The saline-alkali soil improving matrix solves the problem that wood processing waste, flue gas desulfurization gypsum and furnace ash and slag cause environment pollution. Water-logged compost fermentation is conducted on the wood processing waste and duck manure by means of a microorganism fermentation agent. Physical and chemical properties of saline-alkali soil and soil microorganism living environments are improved by means of the organic matrix, a series of problems such as deterioration of physical and chemical properties of soil, nutrient unbalance, soil physical structural damage, acidification, hardening, release of toxic substances and the like caused by blindly applying an excessive amount of fertilizer are avoided, good economic benefits can be obtained, and unnecessary loss is avoided.

Description

technical field [0001] The invention relates to a plant growth substrate, in particular to an improved substrate mainly used in improvement and restoration of saline-alkali land and a preparation method thereof. Background technique [0002] Land resources and their use shoulder a special historical mission in sustainable development. Around the world, land resources are becoming increasingly scarce. Except for extremely harsh areas, human land use has been used in almost all lands and islands, touching the natural world. All factors, and transforming them strongly in utilization, the development and utilization of land resources and the spatial layout of social and economic activities have important positioning functions. Due to the continuous increase of the population, especially the doubling of the past century, the load on the land has become heavier and heavier. "The per capita cultivated land is small and the overall quality of the cultivated land is poor". Land is r...
