以沂蒙短枝、燕山短枝、阳光短枝和莲花栗等短枝型板栗品种为试材,研究其做中间砧对普通型板栗的矮化增产效应。结果表明,以普通实生苗做基砧,短枝型品种做中间砧嫁接的石丰板栗树,其树高、冠径、节间长度均明显小于实生苗砧的同龄树,产量显著提高,果实品质不变。沂蒙短枝做中间砧效果最好,嫁接树的树高、冠径、节间长度只相当于实生砧同龄树的70%、60%和57%,增产幅度为169%。 Short branches of Yimeng short branches, short branches of Yanshan, short branches of sun shrubs and lotus chestnut varieties were used as materials to study the dwarf yield increasing effect of common anvil on common chestnut. The results showed that the tree height, crown diameter and internode length of Shifeng chestnut trees were all significantly smaller than those of the same age seedling, and the yield was significantly increased. The same quality. Yimeng spur to make the best effect of the middle anvil, tree height, crown diameter, internode length equivalent to only 70%, 60% and 57% of the same age ancestral tree, increase rate of 169%.
