浙江全省有340多万亩油菜,如能在开花初期,喷施一点硅素,将对油菜产量产生很大的影响.科学研究和实践证明,硅素对作物有多种作用.硅素能增强作物体质,防止病菌的侵人.经水稻病菌接种试验表明,硅素能增加35.4%～50.5%的抗病能力;硅素又能够增强作物花粉的活力,花粉活力增强,可增加授粉的时间和提高授粉的机率.经试验表明,瓜果类作物施用硅素后成果率提高18%～28%.硅素还能调节作物对氮、磷.钾的吸收,维持作物正常生长.有利于作物开花结果.硅素对油菜结籽和抗白粉病、菌核病、霜霉病也有显著的作用.
Zhejiang Province, there are more than 340 million mu of rapeseed, such as in the early flowering, spraying a little silicon, rapeseed production will have a significant impact.Scientific research and practice have proved that silicon has a variety of crops have a role.Silicon can enhance the crop physique , To prevent the invasion of germs.According to inoculation experiments of rice germ bacteria, silicon can increase 35.4% ~ 50.5% of disease resistance ability; silicon can enhance crop pollen vitality, enhance pollen vitality, increase pollination time and increase pollination probability The results showed that after fructus fructus was fertilized by silicon, the fruit rate increased by 18% ~ 28% .Silicon also regulates the absorption of nitrogen, phosphorus and potassium in crops and maintains the normal growth of crops, which is good for the flowering of crops. Seed and resistance to powdery mildew, sclerotinia, downy mildew also have a significant role.
