本文中总结的夏季修剪试验结果是我们进行的葡萄生长与结果相关性系统研究的一部分成果。在这一部分研究中,观察了玫瑰香葡萄开花、生理落果和种子败育的动态及其相互关系,证明了在开花坐果间期,梢尖幼叶的存在与坐果及种子发育之间的矛盾,适时去除梢尖幼叶诱导有籽果坐果和种子形成的作用与环状剥皮诱导无籽果坐果和种子败育适成鲜明对照,对于这一现象作了初步的分析探讨;发现了生长势不同的新梢的原始结果潜力和对夏剪反应的敏感性不同;根据结果枝在盛花期对摘心最敏感确定了坐果的临界时期,并对结果枝上不同部位及年龄的叶片的功能进行了分析,为适时适度摘心提供理论依据;在不同处理的对比分析中发现浆果品种与摘心后产量水平的差异有较明显的关系,在新梢多次截顶试验中证明了浆果发育的中、后期,同化器官与浆果品质之间的矛盾统一关系已居于主要地位,轻度多次截顶有可能保证或甚至改善浆果品质而不损害树势。 The results of summer pruning trials summarized in this paper are part of a systematic review of the correlation between grape growth and the results we conducted. In this part of the study, we observed the dynamics and correlation of the flowering, physiological decapitation and abortion of Muscat grapevine, and proved the contradiction between the presence of young shoots and the development of fruit and seed, The timely removal of the tip of young leaves induced seed setting and seed formation role and ring-shaped peeling-induced seedless fruit set and seed abortion fit sharp contrast to this phenomenon made a preliminary analysis and discussion; found that different growth potential The results of the original results of the new shoots were different from those of the summer ones. According to the results, the shoots were most sensitive to the topping at the full flowering stage and the critical period of fruit setting was determined. The functions of the leaves at different positions and ages on the branches were analyzed , To provide a theoretical basis for timely and moderate topping; comparative analysis of different treatments found that there is a clear relationship between the yield of the berry varieties and the after-pinning, and in the truncated test of the shoots, it is proved that the middle and late stages of berry development, The conflicting unity between assimilation organs and berry quality is at the top of the list, with slightly more truncations likely to ensure or even improve the berry quality without compromising the tree vigor.
