中文摘要	【目的】揭示锌肥对内陆干旱区棉花产量及品质的影响,为指导锌肥施用提供理论依据。【方法】在棉花生育期设喷施锌肥和喷施清水两个处理,每处理土壤施锌用量分别为0、10、20 kg /hm~2,通过2 a田间试验,研究棉花产量、品质及氮、磷、钾养分吸收特征。【结果】喷施锌肥并土施10或20 kg /hm~2但不喷施锌肥时,棉花产量及增产率最高。施锌方式处理间,喷施锌肥对棉花纤维长度、整齐度及伸长率无显著影响,土施20 kg / hm~2锌肥降低了马克隆值;土施锌肥处理间,锌肥显著增加纤维长度和比强度,降低了整齐度及马克隆值。施锌后棉花对氮、磷、钾的吸收增加,其吸收比例因施锌方式及施锌量的不同而有明显差异,总体上养分吸收比例N高于P低于K。土施锌肥P/N由0.31降低到0.29,K/N由1.09升高到1.17。【结论】土壤施锌是提高棉花单株结铃数的重要途径。在稳定提高单株结铃数的基础上,花期喷施锌肥促进单铃重增加,且提高棉花对氮磷钾的吸收。
英文摘要	【Objective】Investigate the effects of Zn fertility on cotton yield and quality and provide the theoretical basis for guiding the Zn fertilizer.【Method】Two - factor experiments with two methods and three application rate of Zn fertilizer treatments were conducted during cotton growth period. Spraying Zn fertilizer and water was done as the two different spraying treatments and soil application of 0,10 and 20 kg /hm~2 Zn fertilizer was arranged as three fertilizer treatments. Through 2 a field experiment,study on cotton yield,quality and absorption characteristics of N,P,K.【Result】The results showed that when spraying Zn fertilizer and soil application of 10 kg /hm~2 or not spraying Zn fertilizer but soil application of 20 kg /hm~2 the yield and the rate of yield of cotton were the highest. Zn application mode among the treatments of spraying Zn fertilizer on cotton fiber length,uniformity and elongation had no significant effect,while the soil application of 20 kg /hm~2 Zn fertilizer reduced the micronaire value; Soil application of Zn fertilizer fiber length and fiber strength increased significantly,and reduced the uniformity and micronaire value. Application of Zn fertility increased the absorption of N,P,K and the absorption ratio was obvious differences,because of Zn application methods and the mount of Zn fertilizer,the overall nutrient absorption ratio was K > N > P. Only the soil application of Zn fertilizer,P /N decreased from 0.31 to 0.29,K/N increased from 1.09 to 1.17.【Conclusion】Soil application of Zn fertilization was an important way to improve the cotton bolls per plant. On the basis of more bolls per plant,spraying Zn fertilizer could not only increase the boll weight,but also increase the absorption of N,P and K in cotton.
