Chinese water-saving technology for rustic simple delay no

MWR retired experts Qiu as early as 1975 Tudor developed a Chinese-style drip irrigation technology, if popularized in rural areas, saving 50 billion cubic meters per year. However, this technology has not been officially recognized as rustic, simple, dubbed the "old lady lift tube." 79 year old Qiu Water Research for the priesthood in 61 years, is now China Ministry of Science and Technology Market Management and Promotion Center irrigation chief expert, the State Council special allowance. The so-called "old lady lift tube" water-saving principle is that in the fields to install a semi-permanent drip irrigation system, drip irrigation each 50 meters long, 100 capillary tied together below the water, two hours can be automatically irrigated a area, the old lady's role is timed move pipe, an old lady can manage more than 50 roots pipes. This approach is the "soil" of the point, but affordable for rural China. Because the soil is China Irrigation and Drainage Development Center, "shot" on the grounds that by a woman holding a mobile drip irrigation in the field, with the Israeli operation with a computer automated drip irrigation technology is simply immeasurably. Israel is a serious water-scarce countries, world leader in water-saving agricultural technology. Indeed, "the old lady lift tube" with computer-controlled drip irrigation is absolutely not a grade, but we can not put aside national conditions than blindly tech, Eretz Israel is small, farmland scarce, more affluent, computers need to be invested per acre drip irrigation system (translated RMB) nearly 3,000 yuan transformation infrastructure, national paste afford. The "old lady lift tube" only invest 150 yuan per mu, the computer is only 5% of drip irrigation, the device can be used continuously for more than 10 years. China has 18 million mu of arable land, if you are installing computer-controlled drip irrigation, too expensive, the farmers can not afford to dig, the government can not afford to stick. Moreover, the rural surplus labor, a few farmers stood holding water to irrigate the fields completely do it, if that changed computer control, training of farmers and need to invest time. Consider a water-saving irrigation technology is advanced, the key to saving effect. According to water expert analysis, at present China's rural areas still follow the traditional extensive irrigation, water waste. According to statistics, China's agricultural irrigation water needs 340 billion per year to 3,600 billion cubic meters, accounting for 60% of national total water consumption over the utilization of only 46% water, 54% of water is wasted, it is amazing. "The old lady lift tube" annual savings of 50 billion cubic meters of water, who can deny this is not an advanced water-saving irrigation technology? Although the means of "rustic", poorly equipped, simple operation, but this "soil" is precisely adapted to local conditions, in line with rural conditions for farmers need. Suffered severe drought last winter and spring, forcing China into the fast lane water-saving agriculture, promote the use of water-saving irrigation technology is imminent, "the old lady lift pipe" due useless. The huge variety of water-saving irrigation in rural China needs form, because financial constraints difficult to promote drip irrigation computer, so that "the old lady lift tube" play a leading role not do what?
