摘　　要：为研究密度和播期对甘蓝型油菜角果抗裂能力的影响,以6个甘蓝型油菜品种为材料,设置30万、45万、60万hm-2 3种密度和9月25日及10月1日2个播期,分析角果抗裂能力的影响因素。结果发现,密度对角果抗裂能力存在显著影响,这种影响主要因不同密度下品种植株性状和角果特性发生了变化;播期对油菜角果抗裂能力的影响不显著。In this paper, 6 cultivars of Brassica napus were used to study the effect of plant density and sowing date on the shatter resistance of Brassia napus pods.The density set as 30×104, 45×104, 60×104 hm-2，the sowing dates were September 25th and October 1st.The results indicated that planting density had significant effects on the shatter resistance of pods，this impact may be caused by the changes of plant traits and silique characteristics in different planting densities. Sowing dates had no significant effect on anti cracking ability of pods.
