摘  要：
对现代化温室栽培肥水管理技术的初步研究结果表明，不同作物对营养元素的需求不同，黄瓜需要N的比例较高，Ca、Mg和S的比例相对较低；番茄则相反；甜椒介于两者之间。随着生育阶段的延长，作物对营养液的浓度及水分的需求量都有一定程度的增加，在不同生育阶段，番茄还需要调整其营养液配方。影响灌溉量的最主要因素是光辐射强度，即可根据光辐射强度和每天检测所获的回收液EC值来确定。还可以通过回收液的分析和监测来调整营养液的配方。基质温度及pH也是影响作物营养状况的因素之一。

摘  要：
A preliminary study was done on the water and nutrient management of 3vegetable crops under modern greenhouse cultivation. The nutrient demands of cucumber,tomato and sweet pepper are quite different. Cucumber needs a higher ratio of N and a relatively lower ratio 'of Ca, Mg and S; on the contrary, tomato needs a higher ratio of Ca, Mg, S and a relatively lower ratio of N. The nutrient demands of sweet pepper are intermediate between cucumber and tomato. With the growth of the crops, the amount and concentration ofthe nutrient solution supplied also need to be increased of or tomato, the nutrient formula alsoneeds to be adjusted at different growth stages. The most important factor affecting the water supply amount is light intensity, the irrigation amount can be determined by the light intensity and the EC value of drain water from the substrate. The nutrient formula also couldbe adjusted by analyzing various nutrients contained in drain water. The temperature and pHof the rhizosphere are also factors affecting the nutrient status of crops.
