国内外研究表明硼素对植物生殖器官的形成和发育有着密切的关系。硼素丰富可促进作物成熟提高座花率,起到明显的增产效果。实践证明适量的施硼对油菜有良好的增产效果。若用量过低增产效益不明显,若用量过高,甚至可能引起微量元素中毒症。1982年以来,我们试图通过电镜观察不同施硼量对油菜叶肉细胞的变化影响,以探讨喷硼的适宜范围。
Domestic and foreign studies have shown that boron has a close relationship with the formation and development of plant reproductive organs. Boron enrichment can promote crop maturity to increase seat flower rate, played a significant yield increase. Practice has proved that the right amount of boron on rape has a good yield. If the amount is too low Yield benefit is not obvious, if the amount is too high, may even cause trace element poisoning. Since 1982, we have tried to observe the effects of different boron application rates on the changes of the canola cells in the rape by electron microscopy to explore the appropriate range of boron spraying.
