调查四年生初结果山楂幼树的结果母技生长与结果性能看出:结果母枝的生长结果能力随枝长增加而提高,随母枝长势增强而增强,不同类型结果母枝以长者生长结果最佳,短者最差,在形成产量方面,长母枝约相当于短母枝的近3倍。山楂幼树的单果重与花序座果数无规律性相关,提高花序座果率并不明显降低单果重。幼树抽生的结果新梢长度多在15cm以下,表明结果母枝单轴延伸能力不强,结果新梢的结果能力与其上着生的叶片数呈正相关。
The results of the investigation of initial results of four-year-old hawthorn young tree growth and results of the performance of the mother found: the results of growth performance of the parent branch with the increase of the ability to increase, with the mother grow stronger and stronger, The best results, the shortest the worst, in terms of the formation of yield, about two times the length of the mother long branches nearly three times. There was no correlation between the fruit weight of inflorescences and the fruit weight of hawthorn saplings. Increasing the inflorescence fruit rate did not reduce the fruit weight significantly. Saplings shoot results shoot more than 15cm in length, indicating that the results of unilinear extension of the ability of the mother is not strong, the results of the ability of shoots and the number of leaves on it was positively correlated.
