摘要
于2010和2011年采用桂春8号春大豆新品种,在木薯间作大豆模式下,研究播期对大豆产量和主要农艺性状的影响。结果表明:大豆播期固定时,木薯不同播期对大豆产量和主要农艺性状均没有产生显著影响;大豆木薯同期播种时,随着播期的推迟,大豆生育期缩短,株高增加,茎秆变细,分枝数、单株荚数和粒数减少,脂肪含量无明显变化,4月5日播种时,大豆产量和蛋白质含量极显著低于其它处理。综合分析,大豆和木薯在3月25日之前播种的大豆产量、主要农艺性状及间作体系综合效益较好。
Experiments were conducted to research the effects of sowing time on yield and agronomic characters of soybean intercropping with cassava in 2010 and 2011.The results indicated that under fixed sowing time of soybean,cassava sowing time had no significant influence on soybean yield and main agronomic characters.When the soybean and cassava was sown at the same time,along with the sowing time delay,the soybean growth period became shorter,plant height increased,branch numbers decreased,pods and seeds per plant reduced,but had no significant effect on fat content.The yield and protein content of soybean sown on April 5 was lower than other treatments significantly.The soybean yield,main agronomic characters and comprehensive benefits were better when soybean and cassava were sown before March 25th.
