摘要
四种统计方法分析表明:南疆中肥力地区油葵成产因素对产量的作用大小依次是密度>盘粒数>千粒重>秕粒率,各成产因子间存在一定的相互制约和促进作用。增产途径是适当增加密度,兼顾盘粒数和粒重,协调实粒和秕粒比例,改善群体质量,争取群体产量达最高,提出了合理产量结构指标。
The analysis through four statistical ways showed that the functions of factors influencing yield of oil sunflower were density, kernels per disc, 1000-seed weight, the higher un-full seed rate; there were yet restraint and increment relationship between factors of yield . The ways to achieve higher yield should proper increase density and give consideration to kernels per disc and seed weight. The reasonable structure of yield was also proposed.
