摘要
[目的]研究不同施钾量对棉铃发育和纤维品质的效应,旨在为该品种钾肥运筹提供措施依据。[方法]以泗杂3号为试验品种,研究施钾量对棉铃发育和纤维品质的影响。[结果]结果表明:施用适量的钾肥对棉铃发育和纤维品质的改善具有明显促进作用,主要表现为棉铃发育过程中棉铃体积、单铃子棉重、单铃纤维重增加速率较高,棉铃体积、单铃子棉重、单铃纤维重显著增加;纤维长度和长度整齐度有一定提高,比强度、麦克隆值和纺纱均匀性指数显著提高。[结论]综合棉铃发育和最终纤维品质,240 kg/hm2施钾量的促进效应最好。
[ Objective ] The purpose was to study the effect of different potassium (K) application rate on boll development and fibre quality, so as to provide measure basis for K fertilizer management of the variety,. [Method] With Siza 3 as tested variety, the effect of different K application on the boll development and fibre quality, was studied. [Result] The proper application rate of K fertilizer had obvious pmmoting effect on the boll development and fibre quality imprevement, with main performance as that the increase rates of boll volume, seed cotton weight per boll and fibre weight per boll were higher during the boll development and their increases were significant. The fibre length and length uniformity had some increase, and the fibre strength, micron values and spinning uniformity index were enhanced significantly. [Conclusion] Considering the boll development and final fibre quality, the promoting effect of K fertilization at 240 kg/hm^2 was best.
