近年,由于龙眼良种苗木供不应求,许多地方种植了不少的实生苗。实生树结果迟品质差,应行嫁接换种,以提高商品率和经济效益。从本县1990年和1991年春季嫁接的情况来看,龙眼嫁接换种的成活率除与嫁接技术有关外,与接后管理水平也有密切关系。管理得当,成活率可达90％以上,3—5年的实生树通过嫁接,可在嫁接后第三年投产。如管理不当,成活率多不及50％。兹将本县嫁接后的主要管理措施介绍如下。一、抹除不定芽:嫁接树剪顶后,接口下部不定芽迅速萌发,要及时抹(剪)除。据本县梧圹镇沁后村1991年春嫁接后调查,采取及时抹除不定芽措施的成活率达80％以
In recent years, due to the shortage of longan seedlings, many places planted a lot of seedlings. Real-time tree results poor quality late, should be replaced by grafting, in order to improve commodity rates and economic benefits. From the county in 1990 and 1991 spring grafting situation, longan graft survival rate in addition to grafting technology, but also with the level of management is also closely related. Properly managed, the survival rate of up to 90% or more, 3-5 years of real trees through grafting, can be put into operation in the third year after grafting. If not properly managed, the survival rate is less than 50%. Here are the main management measures after grafting in this county as follows. First, erase adventitious buds: grafting tree cut top, the lower part of the interface adventitious buds germination, to timely wipe (cut) addition. According to the survey of villages in Qiuhou Village, Wuhu Town, in the spring of 1991, the survival rate of adopting measures to eliminate adventitious buds in time was 80%
