干旱地区葡萄高效灌溉技术研究

High-efficiency Irrigation Technology of Grape in Drought Area

针对红提，采用立式种植方式，设置沟灌、地表滴灌、地下滴灌三种不同的灌溉方式，通过塔里木盆地阿瓦提丰收灌区的田间对比试验研究。通过三种灌溉方式下土壤含水量在整个生育期内的变化过程、三种灌溉方式下各土层的土壤含水量的变化趋势以及四次灌水前四种灌溉方式下土壤含水量垂直方向的分布试验结果分析。以沟灌平均含水量为基准值，分别计算地下滴灌、地表滴灌的平均含水量的相对增加量。结果表明，在葡萄灌溉定额相同的情况下，最优的灌溉方式为地下滴灌和地表滴灌。

It made comparative and experimental research in the field Awat County in Tarim Basin by establishing three different means of irriga tion-furrow irrigation, surface drip irrigation and subsurface drip irrigation. It is also intended to analyze the change process during the whole growth stage, the changing trends of soil layers, and the distributed experiment results of vertical orientation of the four means of irrigation prior to the four irrigations, respectively of the water content of soil, which is taking average water content of furrow irrigation as reference value to calculate the increasing amount of average water content of surface drip irrigation and subsurface drip irrigation. It is showed that surface drip ir-rigation and subsurface drip irrigation are the best ways of irrigation with the same irrigation norm.
