本项试验调查历时14年(1987～1990)在喀左园艺场进行,试材是2～7年生国光幼旺树,管理条件一般,通过调查基本上找出了喀左幼旺苹果树早产早丰的技术措施。一国光苹果早果性能低的原因1.萌芽力低据调查,修剪的金冠比国光萌芽力高54.8%,不修剪的高13.7%。金冠由于春季萌发的枝量多,全树生长点多,分散了养分供应,控制了树冠,促进形成中短枝,有利于形成花芽,进入早期结果。萌芽力低的国光则全树枝芽少,早果性能低。2.分枝力弱据调查,国光不修剪的和
The survey took 14 years (1987 ~ 1990) in Kazuo horticultural field, the test material is 2 to 7 years Guoguang Wang tree, management conditions in general, basically through the investigation to find out Kazakou Youwang apple tree premature birth early Feng technical measures. The reason why the early fruit of a country’s apple is low in performance 1. Germination is low According to the survey, the pruning golden crown is 54.8% higher than that of Guoguang Germination and 13.7% not being trimmed. Golden crown due to the spring sprouting of more branches, the whole tree growing more points, the dispersion of nutrient supply, control of the crown, to promote the formation of spur, is conducive to the formation of flower buds, into the early results. Low germination Guoguang the whole tree buds less, early fruit low performance. 2. Branching weak According to the survey, the country does not trim and
