对2006～2007年湖北省棉花品种区域试验、冈杂棉8号高产栽培试验及棉花高产创建示范户的有关冈杂棉8号调查的数据资料进行偏相关分析、多元回归分析和通径分析。结果表明,冈杂棉8号皮棉产量(以下简称产量)构成四因子与产量间有着极显著的正相关关系,产量构成四因子对产量贡献为单株铃数>密度>衣分>单铃重。因此,冈杂棉8号的高产栽培关键是在合理密植的基础上,以力争较多的单株铃数为主攻方向。
The partial correlation analysis, multivariate regression analysis and path analysis were conducted on the 2006-2007 regional trial of cotton varieties in Hubei Province, the high yielding cultivation experiment of Gangzaoka No.8 and the data of Gangju No.8 survey on cotton high yielding demonstration households. The results showed that there was a significant positive correlation between the four factors and the yield of Qamzamian 8 on the lint yield (hereinafter referred to as yield), and the four factors of yield contributed to the yield per plant boll number> density> lint> boll weight . Therefore, the key to high-yielding cultivation of Gangzamian 8 is based on reasonable and close planting, and striving for more bolls per plant as the main direction.
