摘　　要：通过测试棉花植株样品的氮、磷、钾含量得知,当样品的烘干温度达到80℃,烘干时间达8小时,就会损失样品中的氮、磷、钾。适宜温度下烘干的样品N、P、K含量明显高于温度过高烘干的样品。试验结果表明:处理A的N、P、K含量比处理B分别低3.948、3.123和1.847 g/kg。Plant N, P, K could be lessened in different drying condition. N, P, K Content with cotton plant with two treatments were tested in this experiment. Results showed that N, P, K of treatment A were lower than N, P, K of treatment B. （80℃ 8 hours） by 3. 948, 3. 123 and 1. 847 g/kg respectively.
