The device that this technical scheme provided can effectively be collected into the rainfall of industrialized agriculture face rain collecting cellar and the deadwood leaf that rainwater is carried under one's arms is tackled, and rainwater flows to crop by drip irrigation pipe uniformly and stably under the very little situation of hydraulic pressure (gravity).The contradiction of moisture supply and demand inequality in the greenhouse vegetable production can be alleviated in this system, and can utilize this system and device that vegetables are applied fertilizer.0.6 mu of this apparatus system collective area, 0.6 mu of drip irrigation area, the drip irrigation of utilizing the rainwater of this apparatus system savings can satisfy maximum " Winter-Spring stubble tomato+autumn and winter stubble cucumber " plantation of greenhouse anniversary water consumption substantially needs water.
Be example with standard greenhouse (thing length 50m, north and south span 8m) and typical crops for rotation (Winter-Spring stubble tomato+autumn and winter stubble cucumber) below, as shown in Figure 4, according to Beijing area average precipitation event month by month for many years, analyze face collection rain retaining and gravity drip-irrigation and need the dynamic relationship of water, to determine the reasonable volume of rain collecting cellar.
(1) face collection rain reservoir storage
Greenhouse area 400m 2(closing 0.6 mu), the industrialized agriculture face is the PE plastic sheeting for farm use of long 50m, wide 9m, thickness can be selected 0.1mm or 0.12mm for use.Average rainfall for many years according to the Beijing area is 66%~85% according to the rainwater collection rate, and is average 75.5%, and calculating theoretical collecting water from runoff is 442mm.
(2) gravity drip-irrigation water requirement
As shown in Figure 5, be example with the maximum crops for rotation of Beijing area greenhouse by solar heat anniversary water consumption (Winter-Spring stubble tomato-autumn and winter stubble cucumber), its growth period and water consumption such as table 1, the whole year, water consumption was seen Fig. 6 month by month, annual accumulative total water consumption is 439.5mm.
Water consumption under table 1 day-light greenhouse winter spring stubble tomato-autumn and winter stubble cucumber anniversary cropping pattern
(3) the reasonable volume of rain collecting cellar
As shown in Figure 7, the drip irrigation water requirement (seeing Table 1) of planting, collection rain face area (400m according to greenhouse vegetable 2), the moon rainfall data (as Fig. 4) in 1985~2008 in runoff coefficient (0.95) and Beijing area, utilize formula (1) and (2) inflow of analog computation rain collecting cellar (rainfall runoff amount), water yield (drip-irrigation water amount) and spillway discharge month by month, analog result sees Table 2.
Y t = min D t S t - 1 - - - ( 1 )
S t = min S t - 1 + Q t - Y t V - Y t - - - ( 2 )
In the formula, Y tBe rain collecting cellar water withdrawal (m 3), S tThe rain collecting cellar water yield (m during expression t 3), Q tFlow into the water yield (m of rain collecting cellar during for t 3), D tFlow out the water yield (m of rain collecting cellar during expression t 3), V represents the dischargeable capacity (m of rain collecting cellar 3).
Collection efficient that the different rain collecting cellar volumes of table 2 rain and alternative underground water scale modeling result
When the rain collecting cellar volume of standard greenhouse correspondence is 90m 3When above, can realize substantially that these routine medium temperature chamber vegetables produce small incidental expenses underground water target (substitute the underground water ratio and reach nearly 90%).But work as the rain collecting cellar volume greater than 110m 3The time, it is very little to the contribution of collecting amount of rainfall that the rain collecting cellar volume continues increase.The general 50m that adopts in the production 3Or 70m 3Rain collecting cellar, substitute the underground water ratio and reach 70% or 80%, comprehensive benefit is better.
In sum, the contrast prior art, technical solutions of the utility model possess following advantage:
(1) utilize the industrialized agriculture face as collection rain face, the fund input of not only having avoided building current collecting field, and collection rain efficient height, the above rainfall of 3mm can form effective runoff;
(2) by collection rain precipitation, filter are set, played the effect of filtering rainwater, purifying water;
(3) rain collecting cellar and gravity cistern play the rainwater of regulating and storing, regulate water temperature, purify water and dissolve the effect that fertilizer carries out fertigation;
(4) carry out a small amount of supply crop water and nutrient repeatedly by gravity cistern and drip irrigation pipeline, can improve crop yield and quality, realize the efficient utilization of rainwater and the target of minimizing mining of groundwater.
(5) according to the scientific and reasonable design rain collecting cellars of situation such as meteorological condition, afflux face area, water catchment efficiency and drip irrigation system of locality, avoided the excessive and too small problem of rain collecting cellar scale.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
