摘　　要：采用每667m2年灌水量350.2t(CK)、233.5t(2/3水)、175.1t(1/2水)3个水分处理,研究了水分对半干旱区日光温室延迟栽培葡萄生长发育的影响。结果表明,灌水能够降低地温,处理间地下15cm、20cm、25cm处温度差异较小,10cm处的地温差异明显,5cm处地温受气温影响最大。第Ⅰ次果实膨大期,果实日均生长量为1/2水>2/3水>正常灌水;第Ⅱ次果实膨大期,果实日均生长量顺序为正常灌水>2/3水>1/2水。果实着色以1/2水处理最早,2/3水次之,正常灌水最晚;穗重、粒重、果实可溶性固形物含量3个水分处理间差异均不显著。The effect of three irrigation treatments,including 350.2t（CK）,233.5t（2/3 of CK）,175.1t（1/2 of CK）/667m2 each year,on growth and development of grape berry of the grapevine cultivated for off-season were studied in semiarid area.The results showed that the soil temperature could be decreased by irrigation,and the obvious temperature differences between treatments and CK happened mainly at the plough soil layer of 10cm under the soil surface.However,those under 15cm,20cm,25cm plough layers showed no significant difference.The soil temperature of the 5cm plough soil layer under the soil surface was influenced much by the climatic air temperature.During the first fruit expanding stage,the most rapid daily growth of grape berry happened when irrigation amount was half of the normal,and the irrigation of two-thirds of the normal amount could do better than the normal irrigation quantity.However,the effects of the three irrigation treatments did differently at the second fruit expanding stage,among which the normal irrigation benefit the grape berry growth most and the 1/2 of the normal irrigation amount did the least.As to the fruit coloring,more watering,later coloring.The weights of berry cluster and grain,and fruit soluble solid content were not significantly different among the water treatments.
