摘　　要：以汾蓖10号杂交种为试验材料,以蓖麻杂交种生物学特征为基础,通过合理调节种植密度、调节个体来探讨蓖麻杂交种群体和个体变化对产量的贡献,旨在寻求合理的高产群体结构,为蓖麻杂交种的高产栽培提供依据。经过2010—2013年连续4 a试验,结果显示,覆膜直播条件下蓖麻杂交种种植密度以1.5万株/hm2产量表现最佳,同密度下蓖麻宽窄行种植产量表现明显优于平均株行距种植。The paper took Fenbi 10 as the test material, based the biological property of castor hybrid, studied the contributions of castor hybrid population and individual variation for yield by adjusting the planting density to find reasonable the high yield population structure, provide basis for high yield cultivation of castor hybrids. The results showed that under the condition of direct seeding, when planting density was 15 000 plants per hectare, yield was the best.
