Description

A new method of planting Juncao to control collapse

technical field

The invention relates to a biological treatment method for collapsed hillocks, in particular to a new method for treating collapsed hillocks by planting Juncao, Oasis No. 1 and the like.

Background technique

Collapse refers to the erosion phenomenon in which the hillside is damaged and collapsed and scoured under the action of water force and gravity. The hazards of collapsing and erosion are second only to landslides and debris flows.

The occurrence and development of collapsing erosion is the result that the erosive force of rainfall splash, runoff, gravity, etc. is greater than the erosion resistance of soil. The size of erosion and corrosion resistance is affected and restricted by various natural and human factors. Among all the natural factors that form collapsed hills, the destruction of vegetation is the main cause of soil erosion, while the human impact is to aggravate the destruction of vegetation. There are 239,100 large, medium and small collapsed hills in seven provinces (autonomous regions) in southern China, with a total area of 1220 km ² collapsed hills.

Due to the destruction of vegetation in the collapsed hillock erosion area, the land resources are severely damaged, and a large amount of sediment produced by the collapsed hillock erosion damages the downstream farmland. The ability of the soil to hold water is significantly reduced, resulting in a lack of downstream water supply and a reduction in the availability of water resources, which completely destroys the land productivity of the entire eroded area.

Benggang is composed of four parts: the collapsed hillock wall, the collapsed hillock ditch, the colluvial body and the alluvial fan. According to the shape of the collapsed hillock, the collapsed hillock can be divided into strip-shaped, claw-shaped, scoop-shaped, and arc-shaped collapsed hills. , Skip-shaped collapse, mixed-type collapse.

There are two types of existing methods to control collapsed hills. The first type is engineering treatment, which uses machinery to push the collapsed hills into platforms for planting fruits and trees; the second type is biological governance, which was adopted in the 1980s. The method is engineering site preparation, the slope is formed into a small horizontal ditch to plant trees and grass, such as sweetgum, sage and bahia grass, kudzu vines are planted along the ditch, intercepting ditches are built at the head of the ditch, grass belts are planted in the ditch, and ditches are built at the mouth of the ditch. Biological governance model of sandbags. However, there are currently three problems in the treatment of collapsing hillocks. The first method uses engineering treatment methods, which require large investment and high cost; the second ecological treatment method involves planting fruits and tea, but the disadvantage is that although planting tea fruits has economic and ecological benefits , but it takes a long time and the effect is slow. It takes two to three years to take effect, and the treatment cost is relatively high. A sapling costs tens to hundreds of yuan; Ecological benefit, poor economic benefit.

Retrieval of relevant materials including Chinese patents shows that there is no relevant report on using Juncao to treat collapse.

Contents of the invention

In order to overcome the deficiencies in the existing methods of controlling collapse, the object of the present invention is to provide a method of planting Juncao to control collapse, which is simple in cultivation method, convenient in management, quick in effect, good in effect, good in ecological benefit, and closely combined with economic benefit and ecological benefit. Methods.

The technical solution adopted by the present invention to solve its technical problems is: a method for comprehensively controlling the collapse of hillocks by planting or growing seedlings and transplanting Juncao, the characteristics of its overall plan are:

1. Set drainage ditches and surface covering nets on the top of the collapsed hillock: dig drainage ditches on the top of the slope with conventional drainage engineering methods, and cover the surface of the drainage ditches with sunshade nets;

2. Paspalum broadleaf is planted in the plot above the side of the drainage ditch on the top of the slope;

3. Juncao planting method in Benggang: transplant giant Juncao with a height of more than 40 cm on the wall of the Benggang, with a spacing of 20 cm between Juncao plants and a row spacing of 80 cm to 1 m, and implement contour planting;

4. Juncao planting method at the bottom of the Bengang ditch: Transplant Oasis No. 1 and Giant Juncao, use the method of contour cluster planting, dig a horizontal ditch with a depth of 30-40 cm and a width of 40 cm at the Benggang mouth; First plant a row of Oasis No. 1 on one side of the alluvial fan, and then plant a row of giant fungus in the same planting ditch close to Oasis No. 1 to form a fence of Juncao; plant another row at a distance of 3 meters;

5. Juncao planting method for alluvial fans: plant giant Juncao seedlings in clusters with a height of 2 m, or use small seedlings with a height of 40 cm; dig a 20 cm deep and 20 cm wide planting ditch for planting, with a plant spacing of 10 cm and a row spacing of 2 m; Juncao planting After 2 weeks, the amount of fertilization was 15 kg/mu of urea;

6. The method of planting Juncao on the edge of the alluvial fan: plant no less than three rows of Oasis No. 1, and use Oasis No. 1 large seedlings with a height of 1.5 m or more to plant in clusters, with a plant spacing of 0.5 m and a row spacing of 2 m; or use small seedlings with a height of 60 cm and a plant spacing of 2 m. 0.2 m, and the row spacing is 1 m.

The sunshade net provided on the market can be used for the covering net on the surface of the gutter.

The described planting of paspalum latifolia adopts the method of sowing seeds.

The transplanted Oasis No. 1 and Jujuncao are Oasis No. 1 or Jujuncao grown for more than one month.

The present invention transplants Oasis No. 1 at the bottom of the Benggang ditch to make full use of the advantages of the Oasis No. 1 pole, which is hard and resistant to burial pressure, water retention, soil retention, and root length (up to 9 m) network soil; (up to 2 m in height), and the characteristics of fast plant growth (fast rooting after being partially covered by soil), etc., to achieve effective management.

The method of planting (transplanting) Juncao in the present invention has the following great advantages:

First, quick results. Initial results will be seen in three months, and significant results will be seen after five months;

Second, the cost is low. Only less than 20% of the cost of traditional biological treatment;

Third, high economic and ecological benefits. Moreover, the ecological benefits and economic benefits can be closely combined. The giant fungus can be harvested after three months of planting, and can be used as 55 kinds of mushrooms, fungus, Pleurotus eryngii, oyster mushroom, Hericium erinaceus, bamboo fungus, and Ganoderma lucidum. Culture medium for edible and medicinal fungi. It can also be used as feed for cattle, horses, sheep, deer, rabbits, geese, fish, and pigs. It can also be used as biomass energy material.

The technology of the present invention for Juncao treatment of collapsing hills is a technology that takes the collapsed hills as a system, adopts giant Juncao, Oasis No. 1 and other Juncao, and combines simple engineering measures for overall treatment. The treatment technology will adopt different methods to control the collapse, collapse wall, colluvial body, slope top surface, etc.

The Juncao planted in the present invention can be used as raw materials for cultivating edible and medicinal fungi and directly used as feed for cattle, sheep, rabbits, pigs, etc., which reduces feeding costs, and can achieve the effect of water and soil conservation, so that soil erosion can be controlled The ecological benefits are combined with the economic benefits of cultivating edible and medicinal fungi and aquaculture.
