龙荔嫁接龙眼、荔枝实验初报

文章目的是利用龙荔耐寒、抗病及适应性强等优势，作为荔枝龙眼育苗的砧木，观察其嫁接亲和性及生长表现，为筛选龙眼、荔枝的矮化、抗旱、耐贫瘠和抗寒砧木打下基础。试验利用一年半生龙荔实生苗作为砧木，分别嫁接龙眼‘石硖’和荔枝品种‘贵妃红’，对嫁接成活率，接穗品种生长势以及开花挂果等进行调查。结果表明，荔枝嫁接在龙荔砧木上，未有一株存活；龙眼嫁接在龙荔砧木上，成活率为38.57%，而嫁接成活的植株第二年开花结果的植株率有11株，占存活株数的40.74%，说明龙荔作为砧木，与龙眼的亲和性较好，具有作为龙眼育苗砧木的可能。

A study of Longan and litchi grafting on dimocarpus confines

This article is designed to study the expression of growth of using dimocarpus confines as the stock to graft longan and litchi. Half a year old dimocarpus confines was used as the stock in this experiment, grafting ''Shixia'' longan and ''Guifeihong'' litchi respectively, investigated the survival rate, growth vigor of scion, flowering and fruit setting. The results show that the survival rate of litchi was zero, and the longan was 38.57%. There was 40.74% the survival longan bloom and bearing fruit in the following year. This proves that the compatibility between longan and dimocarpus confines is better than litchi and dimocarpus confines, it''s one of the potential stock for longan which can enhanced it''s disease resistance and cold tolerance.
