【摘要】 研究了4个播种期对早熟双低油菜品系大地95油菜薹产量的影响。试验结果表明,9月20日至10月20日,播种越早,油菜薹产量越高,其中9月20日播种的产量为27 420 kg/hm~2,经济效益48 450元/hm~2;随着播种时间的推迟,油菜薹产量逐渐下降,但10月20日播种的油菜薹产量仍达11 660 kg/hm~2,经济效益9 050元/hm~2,高于油菜籽的经济效益。更多还原

【Abstract】 In this paper,the effects of four sowing dates on yield of the double-low(low erucic acid and glucosinolate contents),early-maturing rapeseed line Dadi 95 was studied.The results showed that,from September 20 th to October20 th,the earlier the sowing date was,the higher yield of rapeseed stalk gets.When the sowing date was on September20 th,the yield was 27 420 kg/hm~2 and economic benefit was 48 450 Yuan/hm~2.As the sowing date delayed,the stalk yield gradually declined.But on the latest sowing date(October 20th),the stalk yield was still 11 660 kg/hm~2,and the economic benefit was 9 050 Yuan/hm~2 which was still higher than that of rapeseed.更多还原
