| 摘 要： | 为筛选、鉴定钾营养高效品种,在大田条件下,研究了不同供钾水平对不同钾效率类型棉花品种产量及其构成因素和品质的影响.结果表明,泗阳328的产量构成因素较金102具有良好的钾响应,且耐钾肥,属钾营养高效高潜力品种,但供钾量对两者果枝数的影响小;施钾改善了棉纤维上半部平均长度、整齐度、断裂比强度、可纺性指数、黄度等指标,而对马克隆值和反射率影响不大.

| Abstract: | The field experiment was conducted to study the effect of potassium nutrition on yield and quality in the different potassium efficiency cotton varieties.The result showed that the yield and yield components of high K efficiency and high yield potentiality Siyang 328 had respond very well to different potassium supply.But potassium had little effect on fruit branch numbers.Potassium could improve the fiber quality of lint cotton which contained fiber length,uniformity,strength,spinnability,yellowness,and so... |
