摘  要:
本研究以成龄葡萄为研究对象,以水肥作为考量因素,分析不同滴灌水肥处理对成龄葡萄耗水及产量的影响,结果表明:以耗水量作为考量因素,在10个处理下,浆果生长期和浆果成熟期的平均耗水模数高于64%,葡萄在此期间耗水最强即需水最多。在中等施肥量和中等灌水量的配比下,葡萄获得最大的产量,即水肥耦合的最佳模式为灌溉定额6750m3/hm2,尿素489.15kg/hm2,磷酸二氢钾809.40kg/hm2[26]。此时水肥利用达到高效,达到高产目的。

摘  要:
In this study,the mature grapes is taken as studying object,the water and fertilizer is taken into account,the effect of different water and fertilizer treatment on water consumption and yield of mature grape is analyzed.The results show that in terms of water consumption,the average water consumption modulus at berry growth and berry mature periods are higher than 64% under the 10treatments,and the water consumption of grape and the water requirement is the largest;under the medium irrigation and fertilization quantity,the yield reaches the maximum.So the best mode of water and fertilizer coupling is irrigation quota 6 750m3/hm2,urea 489.15kg/hm2,potassium dihydrogen phosphate 809.40kg/hm2,under which the water and fertilizer use efficiency is the maximum and high yield can be obtained.
