Shouguang City, Shandong Province, Zhao Liang Miaoxiang Dongpang Chencun villagers installed in greenhouses Israeli Netafim pressure compensating drippers, tomatoes pilot demonstration of integrated management of water and fertilizer shed. In June, when the harvest of tomatoes, Presbyterian calculations: conventional furrow fertilization, require fertilization 140 kg / mu, water consumption 600 square / acre, power consumption 300 yuan / mu. The use of drip irrigation, fertilization decreased by 66.7% and the amount of irrigation water consumption fell by 66.1%, electricity consumption fell by 54.7 per cent, while tomato production has increased by 13% to 39%.
Lao Chen told reporters, drip irrigation than furrow the province, formerly with furrow irrigation, each 2 to 3 people need, now one person can be. Fertigation, plant relatively strong, fruiting and more fruit Zhou Zheng, but shed little humidity, less disease.
"Helping the world gain more, less investment, is our goal. Our company is in line with the sixth generation of drip irrigation systems and irrigation water and fertilizer use one machine, the realization of water, precise use of fertilizer resources, 50% water, fertilizer more than 30%, but also to prevent soil erosion. Most of Israel's land is barren, desert area in northwest China is similar, but the invention of drip irrigation technology in 1962, Israel opened the door to modern agriculture. For 30 years, the total amount of agricultural water has been stable in Israel 1.3 billion cubic meters, agricultural output has doubled five fold. Due to the wide application of drip irrigation technology, the National irrigated area from 1.65 billion square meters to 22 billion to 2.5 billion square meters of arable land from 1.65 billion square meters to 44 million square On rice, the increase of the arable land is littered with more than one 'kibbutz' (commune). "President Asia Pacific, irrigation company Netafim 狄仕文 said.
National Agricultural Technology Center, chief expert Gao Xiang push shine to cooperation seminar on modern agriculture said that at present China's "water" is more severe than the "lack of land", China is an urgent need to promote the rapid transformation of traditional agriculture to modern and efficient water-saving agriculture. By 2020, China's agriculture to achieve "a controlled two minus three fundamental" should actively develop the integration of water and fertilizer.
China since 1974 has incorporated drip irrigation equipment, has experienced the introduction, digestion and absorption, self-developed micro-irrigation equipment full range of products and applications, test pilot projects to promote micro-irrigation technology, to the partial introduction of foreign advanced technology and equipment, production lines and the country promote the use of micro-irrigation technology , has 30 years of history. Currently, the national water-saving irrigation project area reached 4.07 million hectares though, irrigation water effective utilization coefficient reached 0.52, but the country still has half of the arable land without irrigation facilities, the effective irrigation area of ​​2/3 still follow the traditional backward methods of irrigation .
"China's water-saving irrigation market in great demand, the government is aware of this, but also increase investment of resources, but the lack of scientific and technological content, the industry standard is relatively low. The new concept of business entities in China have begun to shift agriculture on Unlike conventional water-use efficiency rating, willing to spend money to carry out water-saving transformation, but the one-time investment in irrigation equipment is relatively high, the average user is still unbearable. Therefore, the future development of irrigation equipment needs of the market on the Chinese government to give policy-oriented support. "Netafim irrigation Chairman and CEO Ran · Medan told reporters.
