Abstract
The invention discloses a loess flow-collecting field surface flow-increasing, roughness-reducing and solidifying method, which comprises the following steps of firstly removing soil impurities on the surface layer of a ground surface, digging soil loose, removing weeds and impurities: the soil curing agent and the loess are prepared according to the weight ratio of 1: 6-1: 8, are uniformly mixed by sprinkling water, are paved and tamped to ensure that the dry density is more than 1.60g/cm3(ii) a Beating slurry on the tamped collecting surface, spreading pure curing agent on the slurry to smooth the collecting surface, and enabling the roughness to reach 0.012: and (5) regularly sprinkling water on the surface of the prepared current collecting field for maintenance. The loess sloping field collecting surface constructed by the invention has the advantages that the collecting efficiency can reach 80-90 percent, the service life is 15-20 years, the collecting efficiency is basically the same as that of a concrete collecting surface, the loess sloping field collecting surface has no pollution to the environment, the construction cost is 3-5 yuan/square meter, and is only one third of the construction cost of the concrete collecting surface; can be widely applied to vast loess plateau and other areas without sand and stone, and has important practical significance and practical value for promoting the development of drought area rainwater collection and recharge agriculture.
Description
Technical field
The invention belongs to drought-hit area agricultural production and improvement of the ecological environment water saving, retaining and water conservation technical field, relate generally to that a kind of curing loess afflux face of building at hillside fields, loess plateau afflux face is incremental to subtract rough job practices.
Background technology
There is 1,200,000,000 mu in dry farming farmland in China, and no irrigating facility and water condition can only rely on the natural rainfall resource to keep plant growth.The essential measure of realizing dry farming field-crop high yield, stable yields is utilization rate and the utilization ratio that how effectively to improve the natural rainfall resource.Facts have proved that collection rain supplement irrigation agricultural is to realize the effective way of above-mentioned target.The afflux face is an important content of implementing the supplementary irrigation with catchment rainfall technical system, also is one of its key technology.At present, in the few stone area of scarce sand such as loess plateau, adopting soil-solidified-agent to prepare current collecting field is a developing direction.Practice shows and since curing compound fixed be loess, improper as job practices, perhaps surface irregularity is perhaps surperficial dry and cracked, thereby causes poor surface smoothness, has a strong impact on the afflux water catchment efficiency.
Summary of the invention
The objective of the invention is to, seek a kind of smooth surface, rugosity is little, and the curing loess afflux face that water catchment efficiency is high is incremental to subtract rough job practices, adopts this method to solidify loess afflux face, can improve the water catchment efficiency of rainwater.
The technical solution that realizes the foregoing invention purpose is: loess current collecting field surface is incremental to subtract rough curing, at first removes the assorted soil in top layer, the face of land soil is dug pine, removes weeds, foreign material; Be characterized in that soil-solidified-agent and loess are mixed by weight preparation, and the watering mix is even, compacting and piecemeal; Afflux face arsis in compacting goes out slurries, spreads pure curing compound on slurries, receives the face troweling, makes its roughness reach requirement and watering maintenance regularly.
The loess hillside fields afflux face that adopts method of the present invention to build, water catchment efficiency can reach 80%-90%, be 15-20 application life, basic identical with concrete afflux face water catchment efficiency, and environmentally safe, its construction cost be 3-5 unit/square metre, only be 1/3rd of concrete afflux face construction cost; This invention can be widely used in vast loess plateau and other no sand, building stones area, has important and practical meanings and practical value to promoting drought-hit area supplementary irrigation with catchment rainfall Agricultural Development.
