Abstract

The invention relates to a vegetation recovery ecological matrix and a preparation method thereof. The vegetation recovery ecological matrix is composed of, by weight percentage, 20-45% of dry sludge,20-45% of decomposed and dewatered sludge, 12-20% of coir fiber and 12-20% of straw, wherein the dry sludge is prepared by drying dewatered sludge. The vegetation recovery ecological matrix is mainlyprepared from the raw materials of the dry sludge, the decomposed and dewatered sludge, the coir fiber and the straw, and when penetrating through saline-alkali sandy soil via percolate, can providefavorable conditions for survival and accelerated reproduction of soil microorganisms, improve the granular structure of sandy soil, reduce the soil bulk density of the sandy soil, improve the physicochemical properties and the biological properties of the soil, promote soil maturation, accelerate vegetation establishment on barren soil such as the saline-alkali sandy soil and update the soil ecological system.

Description

technical field [0001] The invention belongs to the field of vegetation restoration, and in particular relates to an ecological substrate for vegetation restoration and a preparation method thereof. Background technique [0002] The natural characteristics of most areas in Northwest my country are dry early, little rain, and windy, with serious soil desertification, salinization, and soil erosion. Soil improvement and vegetation reconstruction are one of the important measures to achieve sustainable development in Northwest China. The management and restoration of the ecological environment with the help of plant measures is an important technical measure commonly used at present. Ecological restoration is mainly aimed at four wastelands, dry rivers, abandoned mines, desertified land, saline-alkali land, etc. These areas generally have poor site conditions, poor soil and lack of nutrients, making it difficult to rebuild vegetation. [0003] Soil spraying is a new technology...
