摘要
在核桃生长期7至10月分批进行方块芽接,调查15 d愈合期内的环境温度、湿度及嫁接成活率,并进行X2检验,结果表明核桃生长期芽接适宜的愈活期环境温度是22-30℃,湿度为85％以上。根据本地区不同气候区气象台(站)的气象资料,总结了宜昌境内不同气候区核桃生长期适宜的芽接时间。
The environmental temperature and humidity in wound curing period lasting 15 d, and the survival rate were investigated, by hatchwise square bud grafting during walnut growing period from July to October. By X^2 test, the results indicated that the feasible environmental temperature and humidity were 22 - 30℃ and over 85% respectively during wound curing of walnut bud grafting. The unambiguous time of the walnut bud grafting at different climatic regions of Yichang were summarized by the weather data from the local observatories.
