Problems solved by technology

[0005] The technical problem to be solved by the present invention: the current control of desertification mainly relies on plants to fix sand, but in the process of planting plants, due to the large amount of water and the small amount of water source, the nutrient bowls used do not have the nutrients and water retention functions required by plants , leading to the disadvantages of poor planting effect and low planting survival rate, it provides a method of laying the bottom with perforated moso bamboo tubes, covering soil to dig a hole, then putting the moss-covered micro-rotted wood board into the hole to rot itself, and finally planting in the hole Shrubs as a way to control desertified land

example 1

[0018] First take a circular board with a diameter of 50 cm and a thickness of 5 cm, put it into a biogas tank and soak it for 3 days, take out the slightly rotted board after soaking, and then crush the peat moss with a tissue grinder for 5 minutes, and use the peat moss pulverized Cover the micro-rotted wood board, control the covering thickness to 2cm, and place it under the condition of temperature of 20°C and relative air humidity of 70%, and spray biogas liquid once a day, and the spraying amount is 30% of the total mass of peat moss crushed material , cultivated naturally until the surface of the slightly rotten wood board is covered with moss, and set aside; then take a 5m long and 12cm diameter moso bamboo, use a drill to get through the bamboo joints, and obtain bamboo tubes, and then use an electric drill to evenly drill holes on the surface of the bamboo tubes. Drill 10 rice bamboo tubes, dig a square planting pit with a side length of 50m and a depth of 1m in the d...

[0021]First, take a circular board with a diameter of 50 cm and a thickness of 5 cm, put it into a biogas tank and soak it for 4 days, take out the slightly rotted board after soaking, and then crush the peat moss with a tissue grinder for 8 minutes, and use the peat moss pulverized Cover the micro-rotted wood board, control the covering thickness to 3cm, and place it under the condition of temperature of 23°C and relative air humidity of 75%, and spray biogas liquid once a day, and the amount of spraying is 30% of the total mass of peat moss crushed material , cultivated naturally until the surface of the slightly rotten wood board is covered with moss, and then set aside; then take a 6m long and 13cm diameter moso bamboo, use a drilling machine to get through the bamboo joints to obtain bamboo tubes, and then use an electric drill to evenly drill holes on the surface of the bamboo tubes. Drill 13 rice bamboo tubes, dig a square planting pit with a side length of 55m and a dep...

Abstract

The invention discloses a method for controlling desertification of the Loess Plateau and belongs to the technical field of desertification control. According to the method, perforated moso bamboo pipes serving as ventilating water-collecting pipelines are laid at the pit bottoms to achieve convection with external air, micro-corrosion wood boards and green mosses are degraded completely to supply required growth nutrients to bushes, the green mosses play a water retention role, polylactic acid film coverage can slow down evaporation of water in pits, reed capillary tubes are used for absorbing moisture in air, and accordingly under the synergistic effect, water permeability of soil in pit holes is ensured, water retention is achieved, soil can be moisturized and the planted bushes can also have a sand fixing effect. The method has the advantages that sufficient moisture and nutrients can be supplied to plants, the survival rate of the plants is increased remarkably, and excellent control effects are achieved.

Description

technical field [0001] The invention relates to a method for controlling desertification of loess high slopes, and belongs to the technical field of desertification control. Background technique [0002] Land desertification not only deteriorates the ecological environment, reduces land productivity, threatens the safety of rivers, but also exacerbates poverty in sandy areas. Desertification is one of the biggest environmental-socio-economic problems facing the world today. The rapid expansion of desertified land has caused environmental degradation and huge economic losses, causing political stability and social security issues in some areas, and has become a hot spot of global concern. The Loess Plateau is a relatively typical interlaced development area of ​​agriculture and animal husbandry in my country. Long-term excessive land reclamation, grazing and development have destroyed vegetation and further unbalanced the fragile ecosystem. Land desertification continues to...
