微量元素硼已在油菜、小麦、红花草上应用,并获得了较好效果。1973年,我们在早稻生产上以硼酸钠溶液浸种,播种前进行喷根芽,于抽穗始期进行根外喷雾,均获得一定的效果。经过泥水选好的早稻种子,用1％浓度硼酸钠溶液浸种两天一夜,或齐芽后播种前进行喷雾播种,均能使秧苗生长青秀,根系发达,白根多,绿色体旺盛素质好。(附表) 两种秧苗分别移栽后,从整个生育过程中观察,经硼酸钠处理的生长正常旺盛,特 Trace elements boron has been rape, wheat, safflower grass application, and obtained good results. In 1973, we used sodium borate solution to soak the rice in early rice production, sprayed the root buds before sowing, and sprayed the root outside the initial stage of heading to get certain effect. Seedlings of early rice selected with muddy water were soaked in 1% sodium borate solution for two days and one night, or sprayed and sowed before germination, all of which could make the young seedling grow and develop, root system developed, white root more, and green body had good quality. (Schedule) Two kinds of seedlings were transplanted, respectively, observed from the entire reproductive process, the treatment of sodium borate growth was normal, especially
