苹果矮化中间砧木利用研究

通过8年对金冠、红星、国光3个品种的6个矮化和半矮化砧木的不同组合进行的区域化试验,结果表明,利用矮化或半矮化中间砧可以控制树高、树冠大小,提早成花,早果,早期丰产。利用矮化中间砧,选择适宜的砧穗组合,生产中是可行的。

RESEARCH ON THE USE OF DWARFING INTERSTOCKS FOR APPLES

The purpose of this research is for developing the dwarfing density cultivation of apple orchards.A comparative test has been made to the six interstocks, that is Malling clonal-M2, M4, M7, M9, Malling Merton clonal-MM106 and Malus pumila CV.Jiguan. During this period (1978—1986) the vegetative growth, the characteristic of early bearing, high yield capacity, adaptation and contrary-resistance of various stock-scion combination for apple trees were studied. The results showed that dwarfing apple trees of using M7 or M9 for interstocks can be achived early heavy bearing, whether Golden Delicious, Rails or Starking cultivars. The characteristic of early bearing of Golden Delicious /M7/Micromalus is exceed~ing well. Three years old trees average yield reached to 296.3kg per Mu.Ralls/M7/Micromalus has shown good stable yield. The largest accumulate yield of eight years old trees reached to 5301.1kg per Mu.
