摘　　要：研究了播种量对油菜“赣两优二号”产量、产值、生育期及抗性的影响。结果表明：双低油菜“赣两优二号”适合在江西双季稻区进行免耕直播轻简化栽培，其最高产量、产值分别可达2326．43kg／hm^2、13958．58元／hm^2。在此栽培模式下，赣两优二号适宜的播种量为1．5—1．875kg／hm^2，最佳播种量为1．5kg／hm^2。This experiment in different sowing quantity was carried out to research the effects of sowing quantity on yield, production value, growth duration and resistance of double - low rapeseed Ganliangyou No. 2. The results indicated that Ganliangyou No. 2 was suitable for being cultivated in the double cropping rice region of Jiangxi province in no - tillage direct seeding way, its highest yield and production value could reach to 2326.43 kg/hm^2 and 13958.58 yuan/hm^2 respectively. In this cultivation way, the proper sowing quantity of Ganliangyou No. 2 was 1.5 - 1. 875 kg/hm^2 and the best sowing quantity was 1.5 kg/hm^2.
