嫁接时间最佳时间是新梢开始木质化或半木质化时,此时新梢处于旺盛生长期,易形成愈伤组织。过早易碰断新梢,嫁接难操作;过迟不易形成愈伤组织,不易成活。在昆明,民间有“小满三日扎茶花”的谚语,一般在小满后至端阳节这段时间最好。当然,还要根据各品种的生长特点、花期和新梢发育情况的不同来确定,花期早的品种如早桃红、鹤顶红、雪娇等,新梢萌发早,半木质化也早一些,嫁接时间也相对早;晚花品种如靖安茶、童子面、恨天高等,花期晚,新梢萌发也晚,嫁接时间就晚一些。总之,以新梢刚完全变色、半木质化或刚刚木质化时嫁接为最好。
Grafting time is the best time to begin lignification or semi-lignification shoots, this time in the strong growth of new shoots, easy to form callus. Early easy to break the shoot, grafting difficult operation; too late to form callus, not easy to survive. In Kunming, the folk have “small full three days tie Cha Cameroonian” proverb, usually in Xiaman to the end of the festival is the best time. Of course, but also according to the growth characteristics of each species, florescence and shoot development to determine the different, early flowering varieties such as early peach, Hedysarum, snow Jiao, etc., the early shoot germination, semi-lignification also earlier, Grafting time is relatively early; late-blooming varieties such as Jingan tea, boy face, hatred higher, late flowering, shoots germination late, late grafting time. In short, the new shoots have just completely discolored, semi-lignified or just lignified grafting as the best.
