杨梅是江苏省的特有树种,太湖区域栽培杨梅历史悠久,气候适宜。杨梅四季常绿,耐瘠耐旱,适宜山区绿化,又可产果,是水果淡季的主要树种。经多年实践,杨梅小苗嫁接,移植成活率较低,且管理不便。为此,大力提倡实生苗直接上山,经过3～5年的培育,再行高位嫁接,可明显提高嫁接成活率,且树冠形成快。为证实这一点,我们于1995年进行了杨梅幼树高位嫁接后的不同处理和不同嫁接时期的对比试验,取得理想效果,现将结果总结如下。
Yangmei is an endemic tree species in Jiangsu Province. The cultivation of Yangmei in the Taihu Lake area has a long history and a suitable climate. Yangmei evergreen four seasons, barren and drought tolerance, suitable for mountainous greening, but also fruit, fruit is the main off-season tree species. After years of practice, young bayberry grafted, graft survival rate is low, and management inconvenience. To this end, vigorously promote seedlings directly up the mountain, after 3 to 5 years of cultivation, and then high grafting, can significantly improve the survival rate of grafting, and crown formation faster. In order to confirm this, we carried out in 1995 different methods of high bayberry saplings after grafting and comparison of different grafting period, and achieved the desired results, the results are summarized as follows.
