【摘要】 研究结果表明:旱地糜子对氮、磷、钾的吸收生长前期速度缓慢,吸肥量较少,生长中期速度逐渐加快并达高峰,吸肥量最多,其中氮与钾的吸收高峰在拔节至抽穗期,磷的吸收高峰在抽穗至灌浆期,生长后期速度逐渐减弱,吸肥量明显减少。吸肥量以氮最多、钾次之、磷最少,对氮、磷、钾的吸肥比例为1∶0.29∶0.56。吸肥量与生育日数呈明显的指数相关(r≥0.954)。

【Abstract】 The experiment results indicated that at different growing stages, the nitrogen, phosphorus and K uptakes of Panicum Miliaceum L. varied. The peaks of N and K absorption were found from jointing to heading periods, while the phosphorus’ from heading to filling periods. On the other hand, the total N absorbed was the highest and K and P followed, and the significant correlation was found between absorption capacity of fertilizer and growing time (r≥0.954).
