Application of Drip Irrigation in Sandy Land Shelterbelt

The results of 4-year’s trial showed that when drip irrigation was applied in the establishment of sandy land shelterbelt,the optimal design scheme were as follows:the diameter of drip tube 12 mm,drip flux 3.75 L·h-1,drip space 1.0 m.On the other hand,under drip irrigation,the survival rate of afforestation and increment of tree were both higher than that under normal irrigation condition,and possessed the advantages of water saving,energy saving and labour saving.The design and efficiency of drip irrigation on sandy land shelterbelt were systematically summed up.
