葡萄渗灌节水增产效果试验研究

Test and Study on Effects of Water Saving and Yield Increase of Grapes through Filtration Irrigation

1996、1997年对山西运城试验区葡萄采用渗灌、地面灌、旱地(无灌溉)3种处理方式,研究了葡萄节水与增产的效果。结果表明:渗灌较地面灌平均增产936.8kg/hm2,增产率3.5%;全生育期渗灌较地面灌耗水量平均减少767.3m3/hm2,减少率18.5%,且渗灌节水主要在生育期的中期;渗灌较地面灌平均节水1074.8m3/hm2,节水率39.5%,水分利用率平均为8.27kg/m3,较地面灌平均高1.81kg/m3,是地面灌的1.28倍。

The paper studies the results of the water saving and yield increase of grapes through 3 operational ways of filtration irrigation, surface irrigation and non-irrigation conducted in grape experimental fields in Yuncheng of Shanxi in 1996 and 1997. The results show that comparing with surface irrigation, the mean output increase through filtration irrigation is 936.8 kg/hm2 and increasing ratio 3.5%; the mean consumption reduction of filtration irrigation in total growing period is 767.3 kg/hm^2 less than that of surface irrigation, reduction ratio 18.5% and water mainly saved in the middle of the growing period and; comparing with surface irrigation, the average water saving of filtration irrigation is 1074.8 kg/hm^2 , saving ratio 39.5% and the average water utilization ratio 8.27 kg/hm^2, which is 1.81 kg/m^3 higher in average and 1.28 times of the surface irrigation.
