研究结果,喷施宝叶面肥可以提高水稻植株叶片的叶绿素含量、单株叶片数和株高,减缓低温寡照条件下分蘖的死亡,增加可溶性糖含量,从而提高水稻抵抗分蘖期低温寡照灾害的能力,以受灾后喷用喷施宝效果更佳;在遭受淹水灾害时,施用喷施宝叶面肥可以缓解淹水条件下水稻叶片的衰老变黄和分蘖的死亡,提高谷粒结实率和产量,提高植株可溶性糖含量,增强水稻抵抗淹水灾害的能力;在水稻抽穗期施用两次喷施宝,可以提高水稻的有效穗数、增加结实率和千粒重,减轻稻螟虫灾害,其结实率高于对照57.5%,稻螟虫灾害比对照降低53%,稻谷产量高于对照56.9%。
Spraying foliar fertilizer can increase chlorophyll content, leaf number per plant and plant height of rice plants, reduce tiller death under low temperature and low temperature, and increase soluble sugar content, so as to improve the ability of rice to resist low temperature and low light disaster at tillering stage, In the event of flooding, spraying Penshibao foliar fertilizer can alleviate the aging yellowing and tillering death of rice leaves under flooding conditions, and improve the grain yield and yield Plant soluble sugar content, enhance the ability of rice to resist flooding disaster; Applying Spraying Po twice twice during the heading stage can increase the effective panicle number of rice, increase the seed setting rate and 1000-grain weight, reduce the rice stem borer disasters and its seed setting rate is higher than that of the control 57.5%, rice borer disasters 53% lower than the control, rice yield 56.9% higher than the control.
