龙眼苗含单宁物质多，嫁接成活率低。我们在实践中总结出一套嫁接技术，可使成活率达８０％。现介绍如下：２～１０月均可嫁接，最好在气温２０～３０℃时进行，气温过低不能成活。高温期最好在上午１０点前和下午５点后进行。雨水或露水未干不能嫁接。春天嫁接要盖薄膜防...
Longan seedlings contain more tannin material, graft survival rate is low. We conclude in practice a set of grafting techniques, can make survival rate of 80%. Are introduced as follows: 2 to October can be grafted, the best temperature 20 ~ 30 ℃ when the temperature is too low can not survive. High temperature is best before 10 am and after 5 pm. Rain or dew did not dry grafting. Spring grafting to cover the film anti ...
