River and lake dike protection method implemented by fixing vegetation through straw and grass blankets

Abstract

The invention discloses a river and lake dike protection method implemented by fixing vegetation through straw and grass blankets. The method comprises the following steps that 1, the straw and grass blankets are processed, wherein each straw and grass blanket comprises a surface mesh, a bottom mesh, a nutritive water-retention soil layer, packing paper, a straw layer and a grass seed sowing layer, and the thickness of each nutritive water-retention layer ranges from 8 millimeters to 20 millimeters; 2, a slope of a river and lake dike is neatened; 3, the straw and grass blankets are laid; 4, the straw and grass blankets are anchored, wherein the straw and grass blankets laid in step 3 are anchored to the slope of the river and lake dike through U-shaped bamboo anchoring components, one or more bamboo anchoring components are used in each square meter, one or more bamboo anchoring components are arranged every one meter at the overlapping position of every two adjacent straw and grass blankets, and the width of each bamboo anchoring component ranges from 10 millimeters to 50 millimeters. By means of the river and lake dike protection method, sufficient reutilization of straw can be achieved, and furthermore, vegetation greening for the protected river and lake dike can be achieved.

Description

technical field [0001] The invention relates to a method for fixing vegetation, rivers and lakes embankments by applying a straw blanket, and belongs to the technical field of fixing vegetation, rivers and lakes embankments. Background technique [0002] With the rapid development of human society and industrial and agricultural production, it has led to the destruction of a large number of forests and green vegetation, resulting in the deterioration of the natural environment: tens of thousands of square kilometers of land desertification, the forest area is decreasing day by day, the raging sandstorms, floods, Mudslides, acid rain, etc. At present, the area of ​​soil erosion in my country has reached 3.67 million square kilometers, accounting for 38% of the national area, and the desertification area has reached 2.68 million square kilometers, accounting for 28% of the national land area, and is expanding at a rate of 3436 square kilometers per year. Therefore, the countr...

Problems solved by technology

The former vegetation greening technology is more convenient, but it has higher requirements on the adaptability of grass seeds, and the germination rate is difficult to control. Grass seeds are easily washed away by heavy rain during the sowing period, or eaten by birds, resulting in a large area of ​​blank space; The cost of planting and greening technology is relatively high. The planting of turf rolls requires a large amount of arable land, and the laying of turf rolls requires a lot of transportation costs, personnel costs and maintenance costs.

In addition, the original vegetation greening technology has a relatively single purpose, poor adaptability to the geographical environment, and is not competent for the vegetation greening of river and lake embankments.
