4以色列一家公司采用新方法开发出一种高吸水性聚合物,用其制成储水器埋于农作物根部可显著降低灌溉用水量。该公司采用新技术从天然原料中合成出这种高吸水性聚合物,比从石油中提炼的传统方法更加经济、环保。他们用这种聚合物设计制作成一种储水器,吸满水后埋在农作物根部,植物根据自身需要从储水器中吸收水分。使用这种储水器将节约60%~80%的农业用水量。 4 A company in Israel has developed a new approach to develop a highly water-absorbent polymer that can be used to reduce the amount of water used for irrigation by burying it in the roots of crops. The company uses new technology to synthesize this superabsorbent polymer from natural materials, which is more economical and environmentally friendly than the traditional methods of refining from petroleum. They use this polymer to design a water reservoir that is filled with water and buried in the roots of crops and plants that absorb water from the reservoir according to their needs. The use of such water storage will save 60% to 80% of agricultural water use.
