| 摘 要： | 通过连续四年的盆栽试验和土壤不施肥比较,结果表明,施氮磷钾明显提高棉花纤维品质.氮和钾对品质的影响能力接近一致,磷最小.氮提高比强度的能力强,磷提高比强度和伸长度的能力强,钾提高伸长度和麦克隆值的能力强.最易受氮磷钾影响的品质指标是麦克隆值和伸长度,次为比强度和跨距长度,不易受影响的是整齐度.

| Abstract: | The effect of NPK fertilized in purple soils on cotton fiber quality, compared with unferti-lizing,has been carried through pot-culture and soil test for 4 years . The results are as follows. The fiber quality was obviously increased by fertilizing NPK. The effect of N on fiber quality was about equal to K, which of P was least. The abilities of N increasing fiber strength,P increasing fiber strength and elongation and micronaire value. The fiber quality indices that could be easyly affected by NPK were fiber micronaire value and elongation,then the fiber strength and length, that of could not be easyly affected,was fiber uniformity. |
