摘要
[目的】探讨长江下游地区葡萄适宜的产量负载水平。【方法】以塑料大棚栽培的2～0年生主栽品种巨峰、夏黑、醉金香、美人指等为材料，设置11250—22500kg／hm2的产量负载水平，研究负载量对对果实品质的影响。[结果】随着产量负栽的增加，穗重、果粒重减小，果皮着色程度及果实可溶性固形物含量下降。从穗重、果粒重、果皮着色及果实可溶性固形物含量等综合来看，长江下游地区避雨栽培葡萄的产量宜控制在11250—15000kg／hm2。【结论]确定了长江下游地区避雨栽培葡萄的产量宜控制在11250～15000kg／hm2。
[Objective] The aim was to investigate the appropriate level of the grape＇s fruit load in the lower Yangtze region. [Method] Taking 2- 3-years-old grape Kyoho, Summer black, Zui jin xiang and Manicure finger which cultivated in plastic shed as materials, the effect of fruit load on the fruit quality of rain shelter cultivated grape were studied, by setting the fruit load level between 11 250- 22 500 kg/hm2. [Result] The results showed that ： with the increase of fruit load, the cluster weight and berry weight reduced, and the degree of skin coloring and total soluble solids （TSS） in the must decreased. Considering several elements, such as the cluster weight , berry weight, degree of skin coloring and the TFS, the fruit load of rain shelter cultivated grape in the lower Yangtze region should be controlled 11 250- 15 000 kg/hm2. [Conclusion] The fruit load of rain shelter cultivated grape in the lower Yangtze region should be controlled 11 250-15 000 kg/hm2.
