库车小白杏树体负载量与坐果关系的研究

针对新疆库车小白杏坐果率低的问题,研究了不同树体负载量与坐果之间的关系。结果表明:调查树体的长果枝比率高于中果枝和短果枝,而长果枝的坐果率在4类果枝中是最低的,50%和70%疏花处理以及花期喷施营养液可以显著提高坐果率,4种类型果枝的完全花比例依次为中果枝花束状果枝短果枝长果枝。说明长果枝由于其本身生长较旺负载量较轻,导致树体营养生长和生殖生长失衡,并且形成较多的败育花,从而产生较低的坐果率。而通过疏花和补充营养可以在一定程度上缓解营养生长与生殖生长之间的矛盾,提高坐果率。

The Relationship of Fruit Setting and Tree Load in Akeximixi

Aimed at the key problem of low fruit setting in Akeximixi of Xinjiang Kuche,the relationship betweentree load and fruit set of different trees were researched.The results showed that the percentage of long fruit-bearing branches were more the medium and short fruit-bearing branches in the investigated trees,and fruit setting rate of the long fruit branches was the lowest in the four types of fruit-bearing branch.In anthese stage the 50%and 70% of flower thinning treatment and spraying nutrient solution can...
