荔枝系无患子科,是世界水果中之珍品。原产于我国亚热带地区,已有三千五百多年种植史。然而,嫁接繁育研究较少引起人们重视,生产发展较缓慢。时至今日,荔枝的良种繁育,在我省盛产荔枝的闽南地区,生产上还多采用高压法(本地称圈枝)。这种方法一般“见花压,见果截”,季节性强,母树损失大,繁殖慢。又由于高压苗没主根,易受风害,不耐旱,移栽时成活率较低。所以远远满足不了发展生产的需要。而采用嫁接苗繁育快,可逆性强,恢复生长快,利于发展生产。为此,我们于1984～1985年配合漳州科委,在九湖内僚、漳州农校进行嫁接试验,现将初步结果分述如下:
Litchi Sapindaceae, is the world’s treasures in the fruit. Originated in China’s subtropical regions, has more than 3500 years of planting history. However, grafting and breeding research has drawn less attention and its production has been slower. Up to now, the cultivation of litchi varieties, in the province of litchi rich in southern Fujian Province, the production is still more use of high-pressure method (locally called the circle). This method is generally “see the flowers, see fruit cut,” seasonal strong mother tree loss, reproduction slow. And because of high pressure seedling no main root, susceptible to wind damage, no drought tolerance, lower transplanting survival rate. So far can not meet the needs of the development of production. The use of grafted seedlings fast breeding, strong reversibility, rapid recovery and development, which will benefit the development of production. To this end, we cooperate with Zhangzhou Science and Technology Commission from 1984 to 1985, in the nine lakes, Zhangzhou farming school grafting test, the preliminary results are as follows:
