据研究,硼能加速小麦植株体内碳水化合物和氮素的运转,增强其代谢作用.小麦孕穗期缺硼,影响雌蕊、雄蕊的正常发育,抑制扬粉受精,使每穗粒数减少,空壳增加,千粒重下降.花期缺硼,使小麦开花受到抑制,花药瘦小,花粉粒减少,严重影响开花受精和产量形成.灌浆期缺硼,影响灌浆速度,使饱粒减少,瘪粒增加.实践证明,进行叶面施硼,可
According to the research, boron can speed up the carbohydrate and nitrogen movement in wheat plant and enhance its metabolism.The lack of boron in the booting stage of wheat affects the normal development of pistil and stamen, inhibits the flour fertilization and reduces the number of grains per spike, Increase, grain weight decreased .Floral boron deficiency during flowering, the flowering of wheat is inhibited, the anther thin, pollen grains reduced, seriously affecting the flowering and fertilization and yield formation .Filling boron deficiency, affecting the filling speed, so that grain reduction, increased shrunken .Practice has proved , The leaves of boron, can
