Under the membrane the drip irrigation technology may under the same planter condition, compare with the traditional spate flooding irrigation, the channel anti-seepage and the pipeline water distribution may save water 20~30%, the spray irrigation save water 50%, under the membrane the drip irrigation save water about 75%. This is an agricultural saving water irrigation revolution without doubt. The Shihezi agriculture eight teacher 136 groups are situated at the Eurasia center, the Gurbantunggut Shamo center, southwest the Songorine Basin the edge, the mean annual precipitation only have 107 millimeters, the transpiration rate actually reach as high as 2468 millimeters, is the especially arid agricultural climatic region.
The arid water scarcity has been restricts 136 group agricultural production development the important attribute, because the influence which water scarcity, rolls the field the cultivated area and the crop yield reduces year by year. in 1998, 136 groups introduced under the day industry membrane the drip irrigation saving water technology, 120 Chinese acre cotton experiment field yielded per mu the unginned cotton 280 kilograms in the past, saved water 50% compared to the conventional irrigation, the Chinese acre increases the Inflatable benefit 300 Yuan. in 1999, this group in 6000 Chinese acres newly open up wasteland in the open land carries on under the membrane the drip irrigation dissemination of technology experiment, obtains successfully once more. 136 groups saw saving water has brought the advantage, in 2004 136 group and the production drip irrigation saving water equipment's Xinjiang day industry Limited liability company cooperated, invested 1000 ten thousand Yuan at one fell swoop, increased under the membrane the drip irrigation area 20,000 Chinese acres, caused this group the saving water irrigated area to occupy the entire group total irrigated area 52%. 136 groups 3 lands continually are the typical arid area sands, before 2005 under membrane drip irrigation technology use, this company altogether has 5000 Chinese acres cultivated land, the staff living standard is low. Up to 2005, 3 altogether reclaimed lands have 2000 Chinese acres continually, but entire battery present's land area actually about 13600 Chinese acres. And, after 2005, carries on the cultivation the majority of lands, after is under the membrane the drip irrigation saving water project application, develops the arable land, under the membrane the drip irrigation technology's saving water effect is obvious. 3 staff paid the expensive people to say continually: “3 water resources continually are very scarce, if has not used under the membrane the drip irrigation technology, I am impossible again many kinds of 70 Chinese acre cultivated land, yields per mu is impossible to enhance about 50 kilograms, about each Chinese acre income 260 Yuan. If the present lets me no longer use this technology, I definitely do not want.”
Chinese Project Academy of science 6 academician Inflatable after the investigation and study, the analysis, obtains the science appraisal: The Chinese acre saves water above 50%, each Chinese acre may save water more than 200 cubic meters. Statistics indicated that in 2006 the Xinjiang promotion area 8,400,000 Chinese acres, save water every year 1,450,000,000 cubic meters, yearly average saving water are equal in invest 10,000,000,000 Yuan constructions 15 large reservoirs. in 2007 the shihezi reclaimed district promotes 1,730,000 Chinese acres, yearly average saving water is equal to Beijing dense rain total storage 18%. Some experts have calculated this kind of account: The Xinjiang present actual irrigated area is 60,000,000 Chinese acres, one year consumes the irrigation water Inflatable resources total quantity 44,200,000,000 cubic meters, but in the irrigation the effective use is 21,000,000,000 cubic meters truly. Supposition Xinjiang completes the oasis modern saving water irrigation system project completely, may save water amounts to 28,000,000,000 cubic meters. What is essential, the saving water agriculture is fundamental, has the long-term significance.
