Dune-fixing vegetative cover restoring material and its production

Abstract

A sort of material used for sand-binding vegetation renewing which consists of plant cellulose, microelements, fertilizer, water-absorbable resin and sand. Rainfall can filter into the sand sufficiently to make sure that seed can germinate and grow while in sunny day sand crusts to prevent water from excess evaporation. It is suitable for migratory dune immobilizing and vegetation renewing. The contradiction between chemical sand-binding and vegetation growth can be settled by this material.

Description

technical field

[0001] The invention relates to the fields of ecological restoration and desert control. Specifically, the invention relates to a sand-fixing vegetation restoration material and a preparation method thereof. Background technique

[0002] my country is one of the countries with the largest desertified land area, wide distribution and most serious harm in the world. According to statistics, the area of ​​desertified land in China reaches 1.74 million square kilometers, accounting for 18% of the country's land area. Moreover, the expansion rate of land desertification reaches 3436 square kilometers per year, which is equivalent to the loss of land area of ​​a medium-sized county every year. In recent years, my country's land desertification is still showing a general trend of expansion. The increasingly serious land desertification directly affects the implementation of the national sustainable development strategy, and also threatens the living space of the C...
