摘要
以鄂南第四纪红色粘土发育的棕红壤为供试土壤，研究了大豆、芝麻、油菜、小麦、水稻、玉米等６ 种作物的吸硼规律。建立的植物吸硼模型ＡＰ＝ ＴＢ·ＲＥ·ＡＬ能较好地反映作物吸硼规律。结果表明根系吸硼强度ＡＬ与作物生育期呈非线性关系，根系的吸硼强度因作物和生育期不同而有差距，６ 种作物中以油菜、芝麻较强，不同生育进程中芝麻、油菜随时间推移吸硼强度加强，其它作物随时间推移吸硼强度减小。
This paper studied the boron absorption characteristics of soybean, sesame, rape, wheat, rice, corn on the brown red soil of southern Hubei Province derived from the quaternry period red clay. The models of crop absorbing boron, AP=TB·RE·AL that had been established could accurately reflect crop boron absorption law. The models analysis showed that the intensity of roots absorbing boron, AL , was non linearly related with crops living periods and exsited difference among crops and crops living periods. The absorbing intensity of rape and sesame was enhanced by progress in living period, the others were weaken.\;
