Tender stem crown connection is a new work, especially the use of 4 cold fry side wear adulteration, regeneration of a Pui Ye stable branches of the shoot, there is no report at home and abroad. 1982/1983 and 1983/1984 winter, In order to improve the cold hardiness of GT_1 and restore the normal growth of rubber plantation, the GT_1 saplings aged from 3 to 5 years in the northern reclamation area of Zhanjiang are generally affected by 4 ~ 5 grades of chilling. In the two years from 1983 to 1984, starting from May, That is, the use of cold frog side bud sprouting first Peng is stable twig shoots at the base of the shoots open bud splicing crown crowns, two years crowded with more than 10,000 strains of buds shoot high survival rate, rapid growth, the effect is good, now The situation is summarized as follows:
