不同施肥条件下人工授粉对西番莲的坐果率影响

为了促进西番莲丰产、稳产，研究不同施肥条件下人工授粉对西番莲的坐果率效应。结果表明：不同施肥条件对自然授粉和人工授粉的植株坐果率均无明显影响，但是，相同施肥条件下，人工授粉坐果率显著高于自然授粉的坐果率，而且不同季节授粉效果有明显差异。说明采取人工辅助授粉对于提高西番莲坐果率具有积极效应，该技术值得在生产上进一步推广。

Impact of manual pollination on passionflower Passion fruit-setting rate fruiting under different fertilization levels

Manual pollination was performed on yellow passionflower＇ s flowers under different fertilization levels to test the impact on fruit-setting rate. Results show that fertilization levels affect little on the fruit-setting rate of natural or manual pollination, however, in the same fertilization levels, the fruitsetting rate of nanual pollination will be much higher than that of natural pollination with an obvious variation between trials in different seasons, which show that manpower assistant pollination deserves to be extended in passionflower production to improve the fruit-setting rate.
