提高文冠果坐果率的技术措施研究

为了解决文冠果坐果率低的问题，采用田间试验的方法，进行了提高文冠果坐果率技术措施的研究。结果表明：疏除95％不孕花和疏除100％不孕花处理可极显著提高文冠果坐果率，是对照的4倍多；不同程度的疏除可孕花均有提高文冠果坐果率的效果，坐果率以每个侧生花序保留5朵可孕花处理为最高，可达97％以上；盛花期全树喷洒液体花粉，可以极显著地提高文冠果的坐果率，使其坐果率由4．6％提高到13．8％。

Methods to enhance fruit set percentage of Xanthoceras sorbifolia Bge.

Enhancing fruit set percentage methods were adopted in order to solve the low fruit set percentage of Xanthoceras sorbifolia Bge.The results showed that the fruit set percentage was enhanced significantly by thinning 95% and 100% sterility flowers,and the fruit set percentage was 4 times than that of control;the fruit set percentage was enhanced by thinning some fertile flowers,and that was the highest of 97% by maintaining 5 fertile flowers in one inflorescence;the fruit set percentage was enhanced significantly by spraying pollen solution,and that was up to 13.8% from 4.6%.
