摘要

Reflective ground covers can be used to help trees harvest light that either passes through the leaf canopy or falls within the inter-row zone between trees. We tested this technology in persimmon and kiwifruit orchards. Two reflective ground covers(PE Foil and Tyvek) were placed on the ground beneath 'Fuyu' persimmon trees trained on a Y-Frame trellis, from flowering to fruit harvest (November to May). Numbers of fruits/m2 of canopy were similar between treatments. However, fruits were larger (P< 0.001) on the reflective ground cover treatments (321 and 323 g for Tyvek and PE Foil, respectively) than on the control trees (276 g). Fruit low on the canopy were most affected. Use of reflective ground covers also advanced the date of harvest maturity (skin colour development) by up to 10 days for fruit in the lower canopy. Reflective ground covers were placed beneath Hayward kiwifruit vines trained on T-bars, from just before flowering to fruit harvest (October to May). In the first year, fruits were larger (P < 0.001) on the treated vines than on the control vines (89.4 g and 82.6 g, respectively). In the second year of using reflective ground covers on the same vines, flowering was increased (P < 0.01) with 26.8 and 20.7 flowers per cane for the treated and control vines, respectively. This led to higher fruit yields (P < 0.001) on the treated vines than the control vines (114-87 kg/vine, respectively). Despite this difference in fruit yields, average fruit size was similar on the treated andcontrol vines (107 and 106 g, respectively).
