Embodiment 1

[0017] Taking Bohu County, Yanqi Basin, China as an example, implement the inventive method;

[0018] Construction of farmland backwater drainage ponds in the oasis area:

[0019] In Bohu County, according to the geographical location and topographic features, choose the flat and open location of Guangming Farm and Stud Farm Animal Husbandry in the south of Bohu County, and build two farmland backwater drainage ponds in the open area near the desert area outside the oasis. The drainage pool is 6m long, 3m wide, and 2m deep, that is, the capacity is 36m 3 A water inlet 2 and a water outlet 3 are respectively provided on the top side of the farmland backwater storage pool 1, and a fence 4 with a distance of 2m from the water inlet, a width of 3m, and a height of 2m is provided in the farmland backwater storage pool 1. The slit spacing of the fence 4 is 0.5 cm, which is used to filter impurities such as litter and discarded plastic bags in the farmland backwater drainage, and th...

[0025] Construction of farmland backwater drainage ponds in the oasis area:

[0026] In Bohu County, according to the geographical location and topographic features, choose the flat and open location of Guangming Farm and Stud Farm Animal Husbandry in the south of Bohu County, and build two farmland backwater drainage ponds in the open area near the desert area outside the oasis. The drainage pool is 6m long, 3m wide, and 2m deep, that is, the capacity is 36m 3 A water inlet 2 and a water outlet 3 are respectively provided on the top side of the farmland backwater storage pool 1, and a fence 4 with a distance of 2m from the water inlet, a width of 3m, and a height of 2m is provided in the farmland backwater storage pool 1. The slit spacing of the fence 4 is 1 cm, which is used to filter impurities such as litter and discarded plastic bags in the farmland backwater drainage, and covers the top of the farmland backwater drainage pool 1 with a tarpaulin 5, and the farmland backwa...

Abstract

The invention relates to a new method for effectively utilizing recycled farmland drainage water by vegetation in an arid desert region. The new method is characterized in that the recycled farmland drainage water is guided into a pond built in advance by original anti-seepage canals in an oasis farmland end of the arid region and drainage channels in a desert region, is subjected to filtering treatment, and then flows into the drainage channels in the desert region along the anti-seepage canals of the farmland for survival and growth of the vegetation in the desert. The method can be used for the arid regions containing an oasis and desert ecological system, and a desert vegetation degradation region caused by natural and artificial interference can fully use the recycled farmland drainage water to achieve the effects of effective utilization of water resource, vegetation recovery and revegetation, ecological environment improvement, desertification control and the like. The method solves the problems of water resource lacking in the arid region and difficulty in reutilization of the recycled farmland drainage water for vegetation growth in the desert region.

Description

technical field [0001] The invention relates to a new method for effectively utilizing farmland backwater drainage in arid areas, in particular to a new method for recycling farmland backwater drainage and effectively utilizing desert vegetation. Background technique [0002] In my country, agriculture is the foundation of the national economy. China has made great achievements in feeding almost one-fifth of the world's population with only 7% of the world's arable land. However, since the "Tenth Five-Year Plan" and "Eleventh Five-Year Plan", the total amount of cultivated land has maintained a downward trend, and there is a problem of mismatching water and land resources. It is very important to use water and land resources efficiently. In the arid area, there are problems such as the contradiction between the supply and demand of water resources, the serious diversion of ecological water by domestic and production water, and the serious decline of desert vegetation, which ...
