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.
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:
