摘要
我国北方地处大陆性季风气候区,长年降水少,地上和地下水贮量不足,干旱严重地制约我国北方地区农业的可持续发展。为尽快摆脱干旱威胁,加快旱区农业发展的有效途径是走高效节水型农业发展道路。生物节水、耕作节水、化学节水、工程节水、灌溉节水等五个方面,是作物高产、优质、高效、低耗的综合节水系统工程的主要组成,发展前景十分广阔。
Northern region of China is located in continental monsoon climate area. The annual rainfall is in a short duration, the reserves of groundwater is inadequate. The sustainable development of agriculture has been restricted by serious drough in northern region. For extricating the threaten from drought as soon as possible, the effective way of speeding up agricultural development is to take the effective saving-water type agricultural development road, including saving-water by organisms, by cultivation, by chemicals, by project and by irrigation method and so on. The saving-water agriculture is a synthetic and systematic project for getting high-yield, high quality, high benefit and low cost. Its prospects is very vast.
