几年来,笔者对茶梅、山茶、含笑、银桂和松柏杉等进行不同季节的扦插对比试验。实践表明:秋季扦插的成活率高而稳定,一般都在75%一90终。左右。原因是,浙江地.区秋季的气温高,湿度比较大.霉菌的活动能力减弱,少量扦插易控制温度、湿度和日光条件,有利于生根成活;而春夏季由于土壤温湿度难以控制,霉菌大量繁殖,往往易发霉烂根。
Over the past few years, the author of tea plum, camellia, smiling, silver and pine cedar, etc. cuttings in different seasons comparative test. Practice shows that: the survival rate of autumn cuttings is high and stable, usually in 75% of a 90 final. about. The reason is that in autumn and winter in Zhejiang Province, the temperature is high and the humidity is relatively high, the activity ability of mold is weakened, the temperature, humidity and daylight conditions are easy to control by a small amount of cutting, which is beneficial to rooting and surviving. However, due to the difficulty in controlling soil temperature and humidity in spring and summer, Reproduction, often prone to rotten roots.
