A method for preventing and controlling soil and water loss in arid and semi-arid areas by using garden plants

Abstract

The invention provides a method for preventing and controlling water and soil loss in arid and semi-arid areas by using garden plants, comprising the following steps: step 1): using the landform environment, the area with gullies in the landform is sorted out, and a water storage tank is opened at the bottom of the gully, Along both sides of the water storage tank, arrange the steep slopes into terraces or gentle slopes, step 2): arrange outwards along the terraces or gentle slopes into slopes less than 3°, step 3) introduce irrigation canals, and irrigate the aquifer, requiring water to leach out the medium soil Keep it for 6-12 hours to ensure that the water infiltrates from the inclined holes to the terraces or gentle slopes until it is saturated; step 4) plant lawns and vines on the medium soil layer, pay attention to maintenance for 3-6 cycles, each cycle Pour appropriate amount of water to slopes, terraces or gentle slopes, and culture medium soil layer, and the time of each cycle is 20 to 40 days. During the maintenance period, the dead seedlings are replenished in time. Step 5) carries out normal maintenance, every 50 to 70 days Carry out sequential maintenance until 2 years after the expiration, forming a natural environment cycle 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 western China, 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. 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 livelihood and ecological security. [0004] In the arid and s...

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.
