Description
Technical field
The utility model belongs to the rainwater catchment system technical field, particularly the collection rain gravity irrigation system in hills area, loess plateau step greenhouse.
Background technology
Lofty mountains gully, NORTHWEST CHINA loess plateau district, water resource is poor, and regional seasonal drought water shortage problem is serious.Gully, hills district, loess plateau, the north and drought and water shortage mountain area mean annual rainfall are merely 250-600mm, and concentrate on 7-9 month more than 60%, need water phase serious dislocation with crop.Because special climate, geology and soil condition, the face of land and groundwater resources all very lack in the zone, and water resource of per capita has only 200-500m
3, be the minimum area of national water resource of per capita.The loess plateau belongs to temperate zone arid, semi-arid climate district, has more wide land resources and abundant photo-thermal resource, and this zone makes a clear distinction between the four seasons; Dry, day and night temperature is big, and vegetable melon and fruit can be produced throughout the year under facility condition; Fruit maturation is abundant, and fragrance zoon, carbohydrate, mineral matter and coloring matter form well; Acid content is moderate, for vegetable melon and fruit grow with sucrose accumulation created advantage.
But because North Down district, loess plateau Precipitation Distribution in Time and Space is extremely inhomogeneous, arid is short of rain, dry, has restricted the development of local economy; The rainfall rainwash has not only caused drought and water shortage, but also has caused serious water and soil loss, causes the deterioration of the ecological environment.Drought and water shortage and water and soil loss and to deposit be the critical limitation sex factor of the restriction Loess Plateau sustainable development of socio-economy, therefore, it is particularly important that the rainwater collection storage utilization seems, and large tracts of land gentle slope undulating topography can be used to build or as natural gathering surface.The physical features discrepancy in elevation is beneficial to gravity irrigation, and deep loess has been created the good condition that harvests on the spot.The collection storage utilization of rainfall is an effective way of prevention soil and water loss and Rainwater Resources.
Industrialized agriculture is the important symbol of modern agriculture, can significantly improve the quality and benefits of agricultural production, is the important content in the new countryside construction.Industrialized agriculture can drive the regional economy development, increases farmers' income, and promotes new countryside construction and helps peasant programme; It has increased a large amount of job opportunities, thereby has efficiently solved the problem of outlet of surplus rural labor force as a kind of labour-intensive agricultural; Modernized agricultural production mode as a kind of high yield and high quality; Solving rural area agriculture, rural areas and farmers problem, the pulling agro based economic development advances industry restructuring aspect, rural area bringing into play important effect.Facilities vegetable is higher relatively because of its economic benefit, is the labor-intensive production that is fit to China's national situation, is becoming the new growth point of developing rural economy, industry restructuring in western China.And the enforcement of ecological measures such as the development of industrialized agriculture helps restore vegetation, sand-fixation soil-retention, regulate the climate is for realizing that benign ecological cycles, ecotope improve and important facilitation is played in the sustainable development of agricultural.But shortage of water resources limited should the zone industrialized agriculture development.
Low like rainwater collection, utilization ratio for solution, methods are single, and adaptability has certain limitation etc., and people further investigate industrialized agriculture.
The application number that Inst. of Soil Fertilizer, Sichuan Academy of Agriculture Science applied on July 23rd, 2010 is 201010235097.6 " the collection rain irrigation saving system and the method that are used for hilly upland "; A kind of collection rain irrigation saving system that is used for hilly upland comprises Ji Yutang or Ji Yuyan, high-level reservoir, and low level cistern, water pump and water-supply-pipe, Ji Yutang or Ji Yuyan are arranged on middle part or the bottom of Qiu Gu; High-level reservoir is arranged on Ji Yutang or collects highly the highest body top, mound near each the mound body in rain weir; The low level cistern is a plurality of, is separately positioned on each mound body of high-level reservoir periphery, and it highly is lower than high-level reservoir; Water pump is installed in by Ji Yutang or the collection rain weir; Its water inlet meets Ji Yutang or Ji Yuyan, and its delivery port connects high-level reservoir, and water-supply-pipe is laid between high-level reservoir and each the low level cistern.Use and to collect the rain irrigation saving system; Can the rainwash water that rainfall produces be accumulated in Ji Yutang or the collection rain weir; And the water in Ji Yutang or the collection rain weir carried to high-order cistern with water pump; Respectively the water of high-level reservoir is delivered to each low level cistern through water-supply-pipe, when needing to irrigate, the retaining in each low level cistern is used for irrigating.This application proposes to be used for the collection rain irrigation saving system and the method for hilly upland, needs to build a large amount of cisterns and lays a large amount of pipelines, and cost is high, complicated operation, and needs the power support.
