Ecological forestry sand prevention and soil fixation forest close to desert side and forest establishment method thereof

Abstract

The invention discloses an ecological forestry sand prevention and soil fixation forest close to the desert side and a forest establishment method thereof. The sand prevention and soil fixation forestis divided into three levels from top to bottom; the first level is a plant level, main plants are more than four-year-old strong diversifolious poplar, eight or ten desert wisteria are evenly planted on the edge close to a main rod of each diversifolious poplar, and ammopiptanthus mongolicus is planted in an area which takes the axis of the diversifolious poplar as the center and is 60 cm to 70cm away from the desert wisteria according to the planting density of 0.8 plants / m<2>-1.2 plants / m<2>; the second level is a supply level which is a PPR pipe network 1.5 m-3 m away from the ground surface; and the third level is a closed slow-release level, and the main body of the closed slow-release level is characterized in that biogas digester residues, river bottom sludge and sulfate processpapermaking black liquor are blended into bottom mud, and then the bottom mud is neutralized by sufficient sodium silicate to form a bottom mud layer with the PH of 7-8. The ecological forestry sand prevention and soil fixation forest has the advantages of multiple levels, multiple ecological environments, long fertilizer enrichment period, good sand prevention effect, strong soil fixation and good economy.

Description

technical field [0001] The invention relates to the technical field of ecological forestry, in particular to an ecological forestry sand prevention and soil stabilization forest near the desert and a forest forming method thereof. Background technique [0002] Since modern times, we have all known the term environmental degradation. Many of the reasons for this are that our practice of depleting water for fishing has brought irreparable scars to nature, and desertification is one of them. Desert erosion is an extremely serious hazard. It erodes oases at a visible rate every year. If effective control and improvement are not carried out, it is likely to be covered by sand and dust in the future. People are aware of the seriousness of these problems, so now the country is also very concerned about sand prevention and control. So here comes the question, how to control the boundless desert, [0003] As we all know, the only solution is to plant trees. [0004] Our country's ...

Problems solved by technology

[0005] But there is no doubt that this will not lead to long-term stability. The most fundamental and best way is to rely on sand to eat sand. Developed desert tourism, medicine, etc.

Although the timing is good and the hardware is complete, the most fundamental problem is that there is no supporting ecological planting system in the existing technology, and it is still a bottomless pit of money for sand prevention and soil stabilization.
