影响红豆草开花结实诸因素的探讨

本文通过不同因素对红豆草的开花数、结果率.种子产量及品质影响的观测结果表明.红豆草属于典型的异花授粉植物,昆虫传粉对种子产量及品质的提高具有十分显著的作用;低播量、宽行距、施适量的氮磷肥料、适时灌溉对红豆草种子生产亦有良好的效果。

Some Factors influencing Flowering and Fructification of Common Sainfoin

Some factors influencing flowering,fructification,seed yield and quality of sainfoin were studied.The results obtained showed that the common sainfoin (Onobrvchis sativa Lam.)was a typical cross-pollinated plant,for which insect pollination was of great importance on improving its seed quantity and quality.The low rate of sowing,wide space between rows,proper amount of nitrogen and phosphorous and a timely irrigation also had good effect on seed production of sainfoin.
