Grass blanket with earth evaporation orientated release adjusting function and construction method

Abstract

The invention provides a grass blanket with the earth evaporation orientated release adjusting function and a construction method, and belongs to the ecological restoration technology. The grass blanket with the evaporation orientated release adjusting function is composed of a degradable product (1) and an environment-friendly film material (2), wherein the degradable product is produced by plant fibers or other materials through a processing process and has a certain strength and the water and soil loss prevention function, and the environment-friendly film material has the sealing function and is suitable for the high-temperature and freezing environments. Evaporated steam can be released to the roots of specific plants to meet the requirements of the plants instead of being directly released to the atmosphere, small part of the steam becomes biological substance, part of the steam is used for plant transpiration, the original water circulation is not affected, no negative effect on the original ecology is generated, and the production cost of organic agriculture and the like performed in deserts and other places is greatly reduced. After being degraded, the grass blanket serves as organic fertilizer for the earth to promote positive operation of an ecological system. The construction method includes the working procedures of planning and design of the industry, the product, land and the like, sandy land preparation, fertilization, covering and compounding of grass blanket materials, fixing, seed selection, sowing and the like.

Description

[0001] The world's 162 million square kilometers of land and deserts account for 48 million square kilometers. my country has 1.2 million square kilometers of arable land, but there are 58 square kilometers of Gobi and 700,000 square kilometers of deserts. Desertification is expanding at a rate of 60,000 square kilometers per year. Today The area of ​​desertification has reached 2.62 million square kilometers. This shows the urgency of protecting the desert ecology and the importance of developing the desert. technical field [0002] The invention belongs to one of desert ecological restoration technologies, is also one of organic food production technologies, and is one of human survival and development guarantee technologies. [0003] Jiao Juren (2003) believed that in order to accelerate the recovery of the damaged ecosystem, artificial measures can also be assisted to serve the healthy operation of the ecosystem, and the accelerated recovery is called ecological restoration...

Problems solved by technology

[0004] The current desert ecological restoration technology at home and abroad is mainly for windbreak and sand fixation, or planting desert plants to slowly restore the desert ecology, such as people often use plant fibers and other materials to build windbreak and sand fixation grids in sandy land. ) number: CN201639949U: IPC classification number: A01G31 / 00; A01C1 / 04), also only solve sand-fixing and simple planting, even if adding water-retaining agent, it can not solve the problem of vegetation water demand well, let alone carry out the planting of crops at that time, And the cost is higher
