摘要
为探究黄河流域棉区机采棉最优种植模式,本试验以德棉10号、德棉12号、德棉16号和鲁6269共4个棉花品种(系)为材料,设置76 cm等行距(R1)、66 cm+10 cm(R2)、92 cm+60 cm(R3)3种种植模式,研究各种植模式对不同棉花品种株高、茎粗、产量及纤维品质的影响。结果表明:4个品种的株高均表现为R1>R2>R3,茎粗均表现为R3>R1>R2;品种间株高和茎粗均表现为鲁6269>德棉10号>德棉12号>德棉16号。4个品种均以76 cm等行距种植模式籽棉、皮棉产量最高;各处理中,籽棉产量以德棉10号+76 cm等行距种植模式最高,皮棉产量以鲁6269+76 cm等行距种植模式最高。纤维品质品种间差异较大,以德棉16号和德棉10号表现最优,种植模式对其影响不显著。本试验条件下,76 cm等行距(R1)为最优种植模式。
In order to explore the optimal planting mode of machine picking cotton in the Yellow River Basin,four cotton varieties including Demian 10,Demian 12,Demian 16 and SCRC 6269 were used as experimental materials in the experiment.Three kinds of row spacing were set as 76 cm+76 cm(R1),66 cm+10 cm(R2),92 cm+60 cm(R3)to study their effects on plant height,stem diameter,yield and fiber quality of different cotton varieties.The results showed that the plant height of the four varieties showed as R1>R2>R3,and stem diameter as R3>R1>R2.The plant height and stem diameter showed as SCRC 6269>Demian 10>Demian 12>Demian 16.The seed cotton and lint yield of the four varieties were the highest under the R1 planting mode;among the varieties,the seed cotton yield of Demian 10 was the highest,and the lint yield of SCRC 6269 was the highest.The fiber quality varied greatly among varieties,and that of Demian 16 and Demian 10 was the best;but the influence of planting mode was not significant.Under the conditions of this experiment,76-cm equal row spacing(R1)was optimum.
