几年来,我镇大面积对劣质的品种和用实生苗种植的龙眼树进行高接换种,一般年份成活率可达80％以上,但个别年份遇高温或阴雨低温成活率仅40％以下。如1997年成活率只有32％,按贯例要待来年3—4月才能补接。若在10月小阳春补接成活,可充分利用来年春季生长比势,比来年补接提前一年投产、本人在1997年10月3日对早春未接活的龙眼补接418芽,成活291芽占70％。要点如下: Over the past few years, my town a large area of ​​inferior varieties and longan trees planted with seedlings for high-exchange seedlings, the general survival rate of up to 80%, but the individual years of high temperature or low temperature survival rate of only 40%. If the survival rate in 1997 was only 32%, according to consistent rules to be 3-4 months in the coming year to pick up. If in October the small spring supplements survival, can make full use of the spring than the potential growth in the coming year, the year ahead of complement production, I on October 3, 1997 on the early spring missed live longan to add 418 sprouts, 291 bud life Accounting for 70%. The main points are as follows:
