摘　　要：以3年生红地球为试材,在湖南地区避雨栽培模式下研究了不同负载量对葡萄产量和品质的影响。试验结果表明:在中国南方避雨栽培条件下,红地球单株负载量以留10～12穗果最佳,即产量控制在1 300～1 350 kg/667m2为宜,此时,可溶性固形物含量达到16%,糖酸比较高。随着负载量的增加,果实的外观品质和内在品质均逐渐下降,当负载量超过16穗果时,含糖量仅为12.5%,糖酸比降低。Taking 3-year-old Red Globe as the experimental material,the effects of different loading on yield and quality were researched with shelter cultivation in Hunan.The results showed that in the southern shelter cultivation conditions,it was optimal to stay 10～12 spikes per plant,namely,the production should be controlled between 19 500～20 250 kg/hm2.At this time,soluble solids reached 16%,sugar-acid ratio was high.By the loading increasing,the internal and external quality of fruit decline,as exceeds 16,sugar content was only 12.5%,sugar-acid ratio reduced.
