摘要/Abstract

摘要： 通过2003-2004年不同播期和种植密度试验,确定黑龙江省主栽大豆新品种的适宜播期为4月下旬;由于种植密度不同,直接影响光照在植株群体中的分布,导致植株群体间小气候环境的差异,最终影响产量。试验确定合丰45号、47号大豆品种适宜种植密度在25万株/hm2左右,合辐93154-2大豆品种适宜种植密度在25~35万株/hm2时产量最高。

关键词: 大豆新品种, 适宜播期, 适宜密度

Abstract: The experiments on sowing time and planting density of soybean were conducted in 2003 and 2004 to investigate the suitable sowing time and planting density of new soybean varieties in Heilongjiang Province.The results showed that the suitable sowing time for main cultivated new soybean varieties in Heilongjiang Province was in the last ten days of April.The planting density for new soybean varieties Hefeng 45 and Hefeng 47 and was about 250,000 plant/ha and for Hefu 93154-2 between 250,000 and 350,000 plant/ha.

Key words: New soybean variety, New soybean variety, Suitable Sowing time, Suitable planting density
