通过筛选出适合瓜州县棉区种植的优良棉花新品种，丰富棉花品种类型，促进瓜州县棉花产业可持续发展。以征集引进的7个棉花新品种为试验材料，观察生育特征、产量表现，并对主要农艺性状及抗病性进行比较，筛选出适合瓜州县种植的棉花新品种。结果表明，陇棉16号棉铃大，结铃性较强，丰产性突出，籽棉和皮棉折合产量分别较对照品种酒棉10号增产44.76%、39.99%；中棉113丰产性、早熟性突出，籽棉和皮棉折合产量分别较对照品种酒棉10号增产21.82%、16.98%；庄稼汉902丰产稳产，早熟性突出，籽棉和皮棉折合产量分较对照品种酒棉10号增产17.56%、18.99%；酒棉23号单株结铃数8.7个，结铃性强，生育期适中，抗病性好，籽棉和皮棉折合产量分别较对照品种酒棉10号增产15.64%、19.89%。上述4个品种综合性状表现突出，适合在瓜州县同一生态区作为主推品种进行种植。

In order to enrich the cotton varieties and promote the sustainable development of the cotton industry in Guazhou County, excellent new cotton varieties suitable for planting in the cotton area of Guazhou County were selected. Using 7 new cotton varieties collected and introduced as experimental materials, the growth characteristics and yield performance of new cotton varieties were observed, and the main agronomic traits and disease resistance were compared, and the new cotton varieties suitable for planting in Guazhou County were selected. The results showed that Longmian 16 had large boll, strong bolling and outstanding yield. The average yields of seed cotton and lint cotton increased by 44.76% and 39.99%, respectively, compared with the control variety Jiumian 10. The high yield and early maturity of Zhongmian 113 were prominent, and the average yields of seed cotton and lint cotton increased 21.82% and 16.98%, respectively, compared with the control variety Jiumian 10. Zhuangjiahan 902 had high and stable yield with prominent early maturity, and the average yields of seed cotton and lint increased by 17.56% and 18.99% compared with the control variety Jiumian 10, respectively. The number of boll-setting per plant of Jiumian 23 was 8.7, with strong boll-setting, moderate growth period and good disease resistance, the average yields of seed cotton and lint increased by 15.64% and 19.89%, respectively, compared with that of control variety Jiumian 10. The above four varieties showed outstanding comprehensive traits and were suitable for planting in the same ecological area as of Guazhou County.
