Self-elimination type spiral root-expanding soil-fixing method for preventing water and soil loss of side slope

Abstract

The invention discloses a self-elimination type spiral root-expanding soil-fixing method for preventing the water and soil loss of a side slope, and belongs to the field of water and soil loss of sideslopes. A spiral root-expanding soil-fixing basket serves as a medium, and seeds with developed root systems are planted on the hard side slope with barren soil; on one hand, in the degradation process of the spiral root-expanding soil-fixing basket in the soil, the spiral root-expanding soil-fixing basket can be used as a nutrient for the seeds to make the root systems of plants grow faster andmore stable, and the current situation of the relatively barren soil is improved; and on the other hand, the seeds can be effectively assisted to be planted at the deeper position of the side slope, water resources can be obtained more conveniently in the growth process of the seeds, the survival rate is increased, meanwhile, under the action and guidance of a root-expanding spiral guiding structure, the root systems of the plants grow faster and go deeper into the soil more stably, the growth range and depth of the root systems of the plant seeds are effectively enlarged, the range of a soilfixing barrier formed in the soil is wider and deeper, the slope soil is firmer and not prone to loss under firm grabbing of the plants with the developed root systems, and the slope water and soil loss prevention and treatment effect can be more ideal.

Description

technical field [0001] The invention relates to the field of water and soil loss, more specifically, relates to the related field of slope water and soil loss prevention and soil stabilization. Background technique [0002] In many slopes in the natural environment, the soil is hard and poor, and the roots of plants planted on the soil grow slowly. Therefore, it is easy to cause soil erosion in the slope environment. [0003] In the prior art, simple plant protection techniques are often used for slope protection (such as planting grass, laying turf, planting trees, naturally forming vegetation, or adding concrete protective nets on the slope surface, etc.), but during the process of plant rooting, due to the soil quality Hard, poor soil, insufficient nutrition, the root system of plants on it grows slowly, and the root system cannot be induced by benign growth, and the actual depth of rooting is not enough, or it has not yet taken root in a deep area. The soil will be wash...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a self-contained method of spirally expanding root-consolidating soil for preventing slope water and soil loss. It uses the spirally expanding root-consolidating soil basket as a medium, and the root system is well-developed. Plant seeds are planted on slopes that are prone to water and soil erosion. On the one hand, the spiral-shaped root-enlarging soil basket itself can be used as nutrients for plant seeds during the degradation process in the soil, effectively making up for the poor soil status. On the other hand, It can effectively assist plant seeds to be planted deeper in the slope, making it more convenient to obtain water resources during growth and improve the survival rate. At the same time, under the function and guidance of the self-expanding root spiral guiding structure, it can effectively expand the growth range of plant seed roots , so that the natural soil-fixing barrier formed in the soil has a wider and deeper range, making the slope soil more firm and difficult to lose. Compared with the existing technology, the problem of soil erosion on the slope is significantly alleviated
