| 摘 要： | 在南疆生态条件下对不同氮素水平(155.25、207、258.75、310.5和362.25kg/hm2尿素)处理下的棉花品质进行了大田试验,结果表明氮肥对棉株上、中、下部棉花纤维长度、整齐度、比强、马克隆值存在不同程度的影响。施氮量的增加有助于增加棉花纤维长度和整齐度,氮肥用量超过一定量之后,纤维长度和整齐度显著减少;纤维强度和马克隆值随着施氮量的增加而降低。

| Abstract: | Field experiments were conducted to analyze the change of quality of cotton under different nitrogen levels (337.5,450,562.5,787.5,480 kg urea per hectare) in the south of Xinjiang. The result indicated that the main indexes of fiber quality , such as the fiber length and strength as well as the Macrom value have a negative correlation with the increase of nitrogen application. |
