Method for preventing soil erosion in arid and semi-arid areas by using garden plants

Abstract

The invention provides a method for preventing soil erosion in arid and semi-arid areas by using garden plants. The method comprises the steps of (1) preparing an area with gullies in a landform by using a geomorphological environment, setting a water storage tank at the bottom of a ravine, and forming steep slopes into terraces or gentle slopes along two sides of the water storage tank, (2) forming slopes of less than 3 degrees along the terraces or gentle slopes, (3) introducing an irrigation channel, and watering an aquifer to allow water to soak a medium soil layer to maintain 6 to 12 hours to ensure that the water infiltrates from inclined holes to the terraces or gentle slopes until saturation, (4) planting lawn and vine plants on the medium soil layer, carefully curing for 3 to 6 cycles, pouring a proper amount of water into the slopes, terraces or gentle slopes and the medium soil layer in each cycle, and timely replenishing dead seedlings during the curing period, wherein thetime of each cycle is 20 to 40 days, and (5) performing normalized curing, and orderly performing curing in every 50 to 70 days after the expiration of 2 years to form natural environment cycled maintenance.

Description

technical field [0001] The invention relates to a technology for preventing and controlling water and soil loss in arid and semi-arid areas, in particular to a method for preventing and controlling water and soil loss in arid and semi-arid areas by using garden plants. Background technique [0002] In the western region of my country, the main landforms in arid and semi-arid areas are ravines, which cannot gather water sources. For a long time, soil erosion has been serious. Although the remediation has been carried out in the past, the effect is not very satisfactory. The implanted plants survived. The rate is lower. [0003] Those who look for trees must solidify their roots; those who want to flow far must dredge their springs. The basic role of soil and water conservation in the construction of ecological civilization has been strengthened, and soil and water conservation has provided important support for economic development, social progress, improvement of people's l...

Problems solved by technology

[0004] In the arid and semi-arid areas near towns or villages in western my country, the soil erosion is not very serious. In order to use the defense zone in these areas, improve the ecological environment, and prevent the formation of soil erosion, the current practice is mainly to form forest belts. The survival rate of the country is not high, which also makes the annual expenditure of the country increase day by day. At the same time, with the accumulation of soil erosion, urban and urban construction waste, it also has a certain impact on these arid and semi-arid areas near towns or villages.
