【摘要】 <正> 不同品种的大豆生理特性各异,经济产量差异悬殊。不同品种的大豆要求不同的气候生态环境。由于各地气候、土壤条件不同,所造成的地区间大豆产量的差异是相当大的,甚至比品种造成的差异还要大。在荷泽种植丰收黄大豆比种文丰五号要增产33％,而文丰五号种植在潍坊,比种在济宁要增产39％,在烟台种植齐黄23号比种东懈一号要增产25％,但在烟台种植东懈一号却比济南增产40％。可见选择适宜的品种,选择适更多还原

【Abstract】 Data of regional experiments with six soybean cultivars taken place in six locations in Shandong Province during 1978-1980 were used in this paper. As a result the main factors affected soybean yield were obtained by the analysis of variance. The difference of yields among six varieties in different locations was investigated by SSR testing in LSR on each primary factor. Results of testing indicated that Feng-shouhuang is the highest yielding cultivar available in all regions of Shandong Province; Wenfeng 5 is the lowest yielding cultivar; Weifang is the highest yielding region for all of six varieties; Heze is in the second place. However, there were significant difference among varieties, Jining is the region where soybean yields were low and unsuitable.更多还原
