Embodiment 1

[0016] Embodiment 1 Rice straw woven fabric

[0017] The degradable woven fabric in this example uses rice straw as the material. First, weave the straw into a rope shape with a diameter of 1.2-1.4cm, and then weave the rope-shaped straw into a mesh braid with a grid size of 5cm×5cm , each mesh braid can be made into specifications ranging in length and width, for example, a size of 50cm×50cm, and the weight is about 500g.

[0018] Use effect comparison:

[0019] Yunnan is a province dominated by mountainous and semi-mountainous areas. The mountainous area accounts for 94% of the province's land area. 74% of the province's cultivated land and more than half of the population are distributed in vast hilly areas. Soil erosion seriously hinders the development of mountainous, semi-mountainous areas. The development of production in mountainous areas, along with the loss of topsoil year after year, will pose a serious threat to human survival.

[0020] In the central area of ​​Y...

Embodiment 2

[0032] Comparison of the effects of different braids

[0033] Under field test conditions, palm leaves, straw, and jute fibers were used as weaving materials, and the durability of the three was investigated in terms of water absorption and decomposition. The results showed that straw braids were more conducive to water absorption and durability.

[0034] Table 3 Water Absorption and Decomposition Test Results of Different Woven Materials

[0035]

[0036]

[0037] It can be seen from the above table that straw has the largest water absorption, followed by jute fiber, and palm leaves are the smallest. Good water absorption will have a more prominent effect on controlling runoff. Therefore, from the perspective of water absorption, the water retention effect of straw woven fabrics should be better than that of jute fibers and palm leaves. At 100 days, the small C / N is conducive to material decomposition. Among the three, the C / N of jute fiber is 28, and the C / N of straw...

Abstract

The invention provides a degradable braided fabric in a net structure and knit by knittable plant materials. The knittable plant materials are knit or twisted into rope forms firstly, then knit into a net structure, the diameter of the rope-form structure is 1.2-1.4cm, and the grid size of the net structure is (4-6cm)*(4-6cm). The invention further provides an application of fabric covering in water and soil conservation. A degradable braided fabric cover can not only resist direct rain impact on the soil and prevent the soil from splash erosion, but also reduce the flow velocity and relieve water erosion caused by slow runoff and scour caused by runoff. The degradable braided fabric is an environmental-friendly, economical, friendly and novel land cover material, crop straws are adopted for raw materials, the environment is not polluted, and the soil fertility can be increased through decomposed straws. Additionally, the production technique of the fabric is simple without strict technical requirements, rural vulnerable groups can be fully used, and additional family incomes can be created.

Description

technical field [0001] The invention relates to soil and water conservation technology, in particular to a degradable woven fabric. Background technique [0002] my country is one of the countries with the most serious water and soil loss in the world, and the distribution of water and soil loss is wide and the area is large. According to reports, the area of ​​water and soil erosion in my country is 3.56 million km2, accounting for 37% of the total land area. The erosion forms are diverse and complex. The characteristics of gravity erosion such as hydraulic erosion, wind erosion, freeze-thaw erosion and landslide debris flow are different and intertwined. The causes are complex. According to statistics, the total amount of soil lost in China reaches 5 billion tons every year. The total annual soil loss in the Yangtze River Basin is 2.4 billion tons, of which the total annual soil loss in the upper reaches reaches 1.56 billion tons, and the Yellow River Basin and the Loess ...
