摘　　要：早霜影响无核白鸡心葡萄果实成熟和糖分积累。单因素随机区组施肥试验结果表明:在果园密度3120株/hm^(2)的前提下,施用罗布泊农用硫酸钾可以提高无核白鸡心葡萄果实品质,最佳施肥量为525~675 kg/hm^(2),6月上旬和8月上旬分别施入1/2,果实糖度可达20.50,单粒鲜质量可达8.16 g。Effects of early frost on fruit ripening and sugar accumulation of thompson seedless grape was considerable.The results of single factor random block fertilization experiment showed that the application of potassium sulfate could improve the fruit quality of thompson seedless grape under the condition of orchard density 3120 plants/hm^(2).The optimum fertilization amount was 525~675 kg/hm^(2),in early June and early August,half were applied,the sugar content of fruit was 20.50,and the fresh weight of single grain was 8.16 g.
