高寒冷凉区不同保护措施对新栽红地球苗木成活和新梢生长的影响

Effect of different protection measures on seedling survivance and shoot growth of Red Globe in high-altitude cold area

本试验在2450m高海拔冷凉地区,对新定植的红地球葡萄苗采用套袋、土袋、埋土3种保护处理,都显著提高了成活率、新梢生长量和基部粗度。5月10日定植的苗木,生长80d和160d的调查结果都表现为土袋保护措施较好,而5月24日定植的苗木,套袋保护措施则表现较好。3种保护措施与对照间都表现出了显著性差异,但3种处理间的差异不显著。

Effects of three protection measures of bagging, earth bags and covering with soil on seedling survivance and shoot growth of Red Globe in high-altitude （2450m） cold area were conducted. The results showed that the three different protection measures could increase the surviving rate, shoot growth length and diameter obviously. The performance of seedlings protected by earth bags was better for seedlings planted on 10^th May. But the performance of seedlings protected by bagging was the better for seedlings planted on 24^th May. There were significant differences between the three treatments and CK, and no significant difference between the three treatments.
