Degradable ecological vegetative blanket and preparation method thereof

Abstract

The invention discloses a degradable ecological vegetative blanket and a preparation method thereof. According to the technical scheme, the degradable ecological vegetative blanket is characterized bycomprising a polyethylene net and a thin sponge which are sequentially arranged from top to bottom, seeds, fertilizer and a soil improving agent which are attached to the thin sponge, and hard plastic piles used for fixing, wherein the polyethylene net is connected with the thin sponge through an adhesive. The vegetative blanket is laid on a current-situation-soil construction slope and fixed bythe hard plastic piles, sandy soil is laid on the surface layer of the polyethylene net, and the thin sponge is a natural degradable material. The preparation method includes: removing weeds, gravels,capping mass and sundries on the slope; embedding the thin sponge and the polyethylene net into a position, 10cm in depth, at the top of the slope, and allowing the rest part of the vegetative blanket to attach to the slope and spread; when a second vegetative blanket is need, arranging a first vegetative blanket on the second vegetative blanket in an overlapping manner, wherein the thickness ofthe two overlapped vegetative blanket is 10cm; driving the hard plastic piles into the vegetative blanket to perform fixation, and laying the sandy soil at the upper end of the polyethylene net. Thedegradable ecological vegetative blanket is simple in construction and capable of fast achieving slope greening.

Description

technical field [0001] The invention relates to the field of soil erosion prevention and vegetation restoration, more specifically, it relates to a degradable ecological vegetation blanket and a preparation method thereof. Background technique [0002] Due to the rapid development of modern infrastructure, people can see artificial filling everywhere in the city due to rapid development. The development at the expense of the environment enables early greening of artificial fill through simple construction, which cannot meet the needs of urban greening, and the effect is not ideal; and green vegetation is needed on both sides of the expressway to prevent water and soil Loss, nowadays, as a general greening method, even if it is sown, it is only superficially sown, and it is easy to be washed away when it is dry or rainy. If it is left alone, the germination rate will become extremely low. Therefore, it was invented A low-cost, beautiful and practical plant-growing blanket th...

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a degradable ecological vegetation blanket, the main purpose of which is that the fine-grained soil is easily lost due to rainfall or erosion. In order to promote plant growth, the protection of soil loss cannot be lacked.
