| Abstract: | Drip irrigation is a new technique with the character of water saving,and it is applied mainly in economic crops and economic forest with higher economic values.The authors applied drip irrigation in sandy land shelterbelt cultivation for the first time,and discussed the benefits of water saving,energy saving,labour saving and the investment benefits.The application of drip irrigation technique in various tree species showed that compared with channel irrigation,drip irrigation could increase tree increment by 11.54%,save water,energy and labour by 59.1%,40.5%,and 50.9%,respectively. |
