【摘要】在稻田免耕直播条件下，研究了播种量对赣油杂1号生育期、植株经济性状和产量的影响。结果表明：播种量对赣油杂1号生育期影响不大，该品种全生育期193 d左右，适合于稻田免耕直播；但稀播有利于改善油菜植株的经济性状，不同播种量处理的菜籽产量存在极显著差异。播种量为2 040 g/hm2时油菜产量最高，达到了1 960 kg/hm2，极显著高于其他处理。

【Abstract】 The effects of seeding rate on the growth period，economic characters and yield of Ganyouza No.1 rape directedsowing in rice fields with tillage free were studied.The results showed that the seeding rate had little influence on the period，which was about 193 days.Ganyouza No.1 rape was suitable for directed sowing in rice fields with tillage free.Thin sowing was beneficial to improve the economic charactersThe effect of different seeding rates on the yield had very significant difference.When the seeding rate was 2 040 g/hm2，the yield (1 960 kg/hm2) was the highest，which was significantly higher than the yield with the other treatments.
