两个矮化中间砧对红国光树体生长和果实品质的影响

Effects of two dwarfing interstocks on the growth and fruit quality of Red ralls

以八棱海棠基砧+抗寒矮化中间砧SH6和八棱海棠基砧+矮化中间砧GM256为砧木的红国光幼树为研究对象,仅以八棱海棠为砧木的红国光苹果为对照,研究矮化中间砧对红国光苹果树体生长、果实品质的影响,分别进行了不同密度的栽培对比试验。结果表明:红国光苹果矮化砧嫁接以短枝结果为主,矮化砧成花能力好于八棱海棠乔砧,成花数可增加3倍以上;红国光苹果树体矮化效果GM256>SH6>乔砧;在怀来地区,矮化砧木对红国光幼树果实品质影响不显著。

The effects of Dwarfing interstocks on the growth and fruit quality of Hongguoguang apple trees were studied by using SH6 and GM256 as apple varieties and Malus Robusta rootstock and Hongguoguang apple varieties as materials.The results showed that the dwarfing rootstock grafting of’Hongguoguang’apple mainly produced short-shoot fruit,the flower-forming ability of dwarfing rootstock was better than that of’Malus Robusta’,and the number of flowers could be increased more than 3 times.In Huailai area,the effect of dwarfing rootstock on fruit quality of the young trees of Hongguoguang is not significant.
