摘要 灌溉方法与果园地面覆盖对'Mihowase'温州蜜柑果实品质、产量、果实大小分布与冠幕光水平有一定的影响。试验在南非西开普地区连续进行了两个季节(1994/1995和1995/1996),设微喷、滴灌及滴灌配合TyvekTM(一种白色防渗纤维纸)地面覆盖等3个处理。结果表明:处理间果实颜色、可溶性固形物含量与果汁百分率均无明显差别。然而,滴灌及滴灌结合地面覆盖处理降低果实含酸量,因而趋于提高果实固酸比。处理不显著影响果实选择性采收百分率、产量与果实大小分布。TyvekTM地面覆盖显著(P<0.05)提高进入冠幕下部的地面反射光水平。 The effects of irrigation methods and TyvekTM mulching on the fruit quality,yield,fruit size distribution,and reflected light into the canopy of 'Mihowase' satsuma trees were investigated over two seasons (1994/1995 and 1995/1996 ) in Western Cape region of South Africa. Fruit colour,total soluble solids(TSS) and juice percentages were not affected by any of the treatments in both seasons. However,drip and drip plus TyvekTM mulching decreased fruit total acidity(TA)content,therefore tending to increase TSS/TA ratio. The percentage of fruit selectively picked on different dates,yield and fruit size distribution were not significantly affected by any of the treatments in both seasons. TyvekTM mulching significantly (P<0. 05) increased the reflected light into the lower tree canopy.
