Abstract
The invention discloses a rural slope plastic film combined type repairing method which is used for flattening a slope, cleaning unstable stones and sundries on the slope, respectively arranging drainage channels in the middle of a slope toe or a side slope, then spraying a microspheric curing agent on the slope, then arranging a plurality of wooden piles, wherein the distance between the wooden piles is (3-5) mx (3-5) m, then fixing a fixed net layer on the wooden piles, and the specification of grids in the fixed net layer is (3-5) cmxx (3-5) cm; a planting soil layer is laid on the fixed net layer, the thickness of the planting soil layer is 5-10 cm, and the planting soil layer is formed by uniformly mixing in-situ soil, peat soil, vermiculite and yellow core soil according to the weight ratio of 4:1:1: 1.5; and a plurality of irrigation pipelines are arranged in the planting soil layer, and a degradable mulching film is laid on the planting soil layer. The method can realize the water and soil conservation of the slope, improve the ecological environment of the slope soil and effectively protect the water and the fertility in the soil.

Background
The slope farmland refers to dry land which is distributed on a hillside and has poor flatness, water running, fertilizer running, soil running and low crop yield, and generally refers to a landform type of 6-25 degrees. With the adjustment of agricultural industrial structure, large-area slope farmland is developed and utilized, which brings considerable economic benefit, but because of extensive mountain land development and farming mode, the surface ecology is seriously damaged, which causes a series of problems of serious water and soil loss, low land productivity, reduced water storage capacity and the like, and directly influences the rural economic development and the income increase of farmers.
With the increasing emphasis of ecological environment protection, a great deal of research is carried out on the treatment and restoration of slope farmland, at present, a treatment mode of changing slope into ladder is often adopted, for example, the original cultivation table top is treated into a horizontal cultivation table by adopting engineering measures, horizontal terraced fields can also be built at intervals, and the horizontal cultivation table top and the un-leveled cultivation slope are arranged alternately after leveling. However, in the engineering construction process of changing the slope into the ladder, the problems of too narrow or too wide terrace surface, inadequate water storage and drainage facilities, great difficulty in repairing the terrace in the steep slope and the like easily occur. The method for treating and repairing the slope farmland by utilizing the pile, net and grass cooperative system similar to a slope protection method has the advantages that although the construction difficulty and the cost are reduced, the effects obtained in the aspects of protecting the moisture and the fertility of the soil, promoting the propagation of microorganisms, improving the ecological environment of the soil and the like are poor, and further research and improvement are needed.
