摘  要：
采用正交试验设计L18(37),开展了播期、密度及施N量对3个宽柄芥新品系经济产量影响的研究。试验结果表明,品种和播期对产量影响表现为极显著;施N量和种植密度对产量影响表现为显著,最优高产处理组合为A2B2C3D1,即在重庆市涪陵区沿长江生态条件下,宽柄芥种植应选择中晚熟新品系DJ、播期为9月6日、种植密度为3 500株/667 m2、施纯N量20 kg/667 m2,可获得高产。

摘  要：
In this paper, we carried out a experiment with four factors, three levels and two repeats of the orthogonal test design L18(37), studied effects of sowing date, density and N fertilizer application amount on economic traits of three new wide handle mustard strains. The results showed that, effects of cultivars and sowing dates on yield was extremely significant, effects of N fertilizer application amount and planting density on yield was significant, and the most excellent high yield combination was A2B2C3D1. Along the Yangtze River ecological area in Fuling district of Chongqing city, we should select new middle-late mature wide handle mustard strain DJ which sowing date was September 6th, planting density was 3 500 plants every 667 m2, and N fertilizer application amount was 20 kg/667 m2, then we could obtain high yield.
