| 摘 要： | 以金农棉1号F1代杂交种为材料，研究了棉花漂浮育苗移栽棉和免耕直播棉不同播期和不同密度下对棉花的产量构成因素、成铃分布情况及各种成本、产值及利润的影响。研究结果表明：在单株成铃方面，只有处理1和处理6高于对照：各处理的单铃重都大于ck．其中以处理1的最重．迭到了6．59g．比ck大；各处理之间表分差异不显著；而在皮棉产量和籽棉产量、产值以及利润上．处理3最大。其次是处理4。

| Abstract: | using Jinnongmian No. 1 hybrid seeds （F1） as material to study cotton yield components, boll sistribution, Cariety costs, output and profit under the condition of cotton of floating breeding seedling transplant and no - tillage cultivation by direct seeding in different sowing dates and different density. Deal 1 and deal 6 under 18000zhu/hm2 single plant bolls are more than CK＇s. All deals single boll weight are heavier than ck＇s. Among all deals gin turnout difference is not significant. In lint yield and unginned cotton yield, output and profit, deal 3 is biggers. Deal 4 is followed. |
