PVC管道或砌护渠道输水与开沟灌溉相结合的造林方法及效果

Forestation Practice of Combining PVC Tube or Slab - Lined Canal Water Transport with Ditch Irrigation and Its Impacts

开沟灌溉造林与大田平灌相比,具有总体用水量少,局部给水量多的特点,能够显著地提高灌溉效率, 提高造林成活率和林木生长量。同时,利用管道和砌护渠道输水,可防止渗漏,提高水的利用率。

Compared with flooding irrigation of field forests the irrigation of ditch bed forestation can reduce total water demand, provide more water for specific plots, save water, improve irrigation effects significantly and increase tree survival rate as well as growth. Moreover, use of tubes and slab -lined canals for water transport can increase water use efficiency and prevent leakage.
