摘　　要：为探寻无膜棉成铃分布及铃重变化的影响因素,开展了棉花不同行距配置试验。选用中棉61品种进行播种,采用3种不同行距配置,分别为A(3行):76cm+76cm+76cm;B(4行):66cm+(76cm+10cm+76cm);C(6行):66cm+10cm,对3种行距配置下棉花成铃时期和结铃吐絮时期数据进行分析。结果表明,3种不同行距配置的中、下部铃成铃随行距的减少呈上升趋势,而上部铃呈先上升后下降的趋势,4行的总铃数最高,比3行与6行分别高0.6个、2.7个。内、外围铃均以4行最高,分别比3行与6行高2.8个、3.9个。铃重在棉花纵向与横向上均以4行的铃重最高,纵向分别比3行与6行高6.8g、22.7g,横向分别比3行与6行高14.7g、31.3g。产量则以6行最高,为5173.5kg/hm^(2),分别比3行与4行高967.8kg/hm^(2)、439.7kg/hm^(2)。而其他因素(单铃重、皮棉重、籽棉重、衣分)均以4行为最好。综合分析成铃分布与铃重,在3种行距配置中,最好的为4行;产量则以6行最高,其次为4行,3行最低。In order to explore the influencing factors of boll distribution and boll weight change of cotton without film,the experiment with different row spacing configurations of cotton was carried out.In this experiment,zhong61 was selected for sowing,and three different row spacing configurations were adopted:A(three rows):76cm+76cm+76cm;B(four lines):66cm+(76cm+10cm+76cm);C(six lines):66cm+10cm.Then cotton into the bell period under the three row spacing and boll boll opening period for sample selection,measurement,recording,data processing,and then through the results of data analysis,three different row spacing of middle and lower part of the bell in the bell with the decrease of distance on the rise,while the upper fluid downward trend after rising first,four lines of the highest total number of the bell,above three lines and six lines,0.6 and 2.7,respectively.In the comparison of inner and outer bells,the fourth line was the highest,which was 2.8 and 3.9 higher than the third and sixth lines,respec⁃tively.In comparison of boll weight,the boll weight of four rows of cotton was the highest in both longitudinal and transverse directions,which was 6.8g and 22.7g higher than that of three and six rows in longitudinal direction,and 14.7g and 31.3g higher than that of three and six rows in transverse direction,respectively.In terms of final yield,the sixth row had the highest yield of 5173.5kg/hm^(2),which was 967.8kg/hm^(2) and 439.7kg/hm^(2) higher than the third and fourth rows,respectively.And other factors(single boll weight,lint weight,seed cotton weight,lint percentage)are the best four lines.Therefore,through the comprehensive analysis of boll distribution and boll weight,it is concluded that the best configuration of three row spacing is row 4.In the comparison of final yield,row 6 is the highest,fol⁃lowed by row 4 and row 3 is the lowest.
