Background technology
The appearance of industrialized agriculture increases sharply protection ground crop genetics area.To calendar year 2001, China's vegetables facility cultivation area has reached 2,000,000 hm
2, it mainly concentrates on suburb, big-and-middle cities and towns.A large amount of agricultural waters forms with resident, water for industrial use and conflicts, and the contradiction that makes water resource utilize is more outstanding, and the Research Significance of therefore actively carrying out the facility cultivation water-saving technology is far-reaching.
From rainwater resource, global annual quantum of rainfall reaches 10,000,000,000,000 m
3, China is 5,000,000,000,000 m
3, China's southern area particularly, rainfall is abundant.Therefore, design utilizes greenhouse canopy face to collect rainwater, and carries out gravity irrigation by the natural discrepancy in elevation of the water surface in the water-storing device, not only reduces and irrigates operation energy consumption, and maximally utilise rainwater resource, fully reach water saving, energy-conservation, the purpose of improving greenhouse.
Summary of the invention
The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and a kind of greenhouse canopy face collection rain and gravity irrigation device are provided.
The purpose of this utility model is achieved in that
The utility model comprises greenhouse, rain-harvesting trough, collecting pipe, cistern, filter, flow control valve, main and irrigate band;
The left and right sides at greenhouse canopy face is respectively arranged with rain-harvesting trough, and the end in the bottom, greenhouse is outside equipped with cistern, is connected successively before and after rain-harvesting trough, collecting pipe and the cistern;
Delivery port in the cistern bottom is provided with filter, is provided with main and irrigate band in the bottom, greenhouse, is connected successively before and after filter, flow control valve, main and the irrigate band.
Operation principle of the present utility model is:
During rainfall, rainwater flows to collecting pipe along the both sides rain-harvesting trough, introduces cistern by collecting pipe and stores; During irrigation, the rainwater that has certain deadweight in the cistern is by the filter flow control valve of flowing through, by the unlatching of flow control valve control water outlet, close and the flow size; Rainwater passes through the main uniform distribution to each irrigate band again through the main of flowing through behind the flow control valve; Affact near the topsoil crop root zone by drip irrigation, supply with crop root moisture, the purpose that realizes that rainwater is collected on the spot and irrigate on the spot.
The utlity model has following advantage and good effect:
1. utilize greenhouse canopy face collection rain, under rainy district, south rainfall normal condition, can satisfy the needs of crop irrigation basically.
2. greenhouse canopy face collection rain both can reduce water and soil loss, and water quality is better relatively.Compare with large-scale Ji Yuchang, also can reduce investment, be convenient to implement.
3. the gravity that utilizes water self is as power, and simple structure is invested for a short time, and saves energy reduces cost.
4. adopt the irrigate band to carry out root district localized irrigation, moistening crop root zone soil, provide a metastable growing environment of water capacity to crop, reach the requirement of " irrigation is to irritate crop rather than irritate soil ", fundamentally improve the water utilization benefit. can also reduce simultaneously invalid evaporation and indoor humidity between greenhouse soil, improve indoor environment, improve the yield and quality of fruits and vegetables.
The utility model is applicable to southern area of heavy rainfull plastics Dan Dong and attached-greenhouse.
