摘  要:
为了弄清不同土壤棉花施用钾肥的最佳用量 ,在耕脱潮土上安排了不同用量钾肥试验。结果表明 ,棉花在耕脱潮土上施用钾肥的最佳K2 O用量为 34 1.8~ 369.7kg/hm2 ,其氮、磷、钾的最佳组合为纯N 2 2 5kg/hm2 ,P2 O512 0kg/hm2 ,K2 O 34 1.8~ 369.7kg/hm

摘  要:
To identify optimum application dosage, test of potash fertilizer rates were designed in Flove aquic (cultivation modified) soil.The results showed that the optimum dosage for K 2O was 341.8~ 369.7 kg/hm 2 and its optimum NPK rate were net N 225kg/hm 2, P 2O 5 120kg/hm 2 and K 2O 341.8~ 369.7 kg/hm 2.
