植物需水量
植物需水量-
微灌系统利用IT技术测量植物所需水量，可以大幅提高产量。
Micro-irrigation systems that use IT to gauge exactly how much water needs to be dripped on plants could boost yields dramatically .

通过对拓展模型的分析求解发现，植物的年需水量主要取决于叶片面积和土壤的水分状况，日需水量主要取决于太阳辐射、大气温度和大气湿度。
From simulation of the models we found that utilizing water of plant depended on leaf area and soil water condition in a year . And the utilizing water in a day depended on solar radiation , atmosphere temperature and humidity .
