解放以来,我国苹果栽培面积迅速扩大,促进苹果提早结实已成为重要的研究课题。实现提早结实,应保证树冠形成健壮的骨架。生长旺盛有利骨架形成,但常延迟结实;生长偏弱不宜骨架建造,但容易趋向开花。两方面似乎存在矛盾。从分析生长健壮结实较早的树株得到启发,其新梢组成有别于以上两种情形,它们的树冠中生长期长,生长量大的新梢数量适度,早期停止生长并且有顶芽的新梢较多,有足够的营养枝用于整形,有大量的侧枝早形成花芽开花结果。看来是研究解决上述矛盾有希望的线索。1959—1963我们从新梢组成及其发生,影响梢形成和新梢组成的因素等方面进行了调查研究。皆在探求提早结实的形态指标和控制调节途径。调查主要是在莱阳园艺均及烟台园艺果园中进行的。分析新梢组成与结实关系时,把
Since the liberation, the area of apple cultivation in our country has rapidly expanded. It has become an important research topic to promote the early fruiting of apples. Achieve early and strong, should ensure that the crown to form a strong skeleton. Strong growth conducive to the formation of the skeleton, but often delayed and strong; weak growth should not skeleton construction, but tend to flowering. There seems to be a contradiction between the two. Inspired by the analysis of robust and strong earlier-growing trees, the shoot composition differs from the above two cases in that their canopy has a long growing and high-growth shoot with a modest number of shoots that stop growing early and have a terminal bud Shoot more, there are enough nutrients for plastic surgery, there are a large number of lateral flowering bud formation early results. It seems that there are promising clues to studying and resolving the above contradictions. 1959-1963 We conducted a survey on the composition of the shoot and its occurrence, the factors that affect the formation of shoots and shoot formation. Are looking for early signs of strength and control of regulatory approach. The investigation was mainly carried out in both Laiyang horticultural and Yantai horticultural orchards. When analyzing the relationship between shoot composition and fruiting, put
