【摘要】 选择9个来源于黄淮海地区的大豆品种,在播后苗前用乙草胺进行土壤处理,研究了乙草胺对不同大豆品种的生长发育及产量和品质的影响。结果表明:不同大豆品种对乙草胺的敏感性有差异。2 250 mL/hm2处理,冀豆7号和五星1号药害症状较轻,冀豆7号、冀黄13号、五星1号和鲁99-10的株高有所增加,其它品种的株高均降低;喷施乙草胺,所有参试品种的单株荚数、单株粒数、单株粒重及产量均低于人工除草,但是冀豆7号和五星1号减产幅度较小;中作011大豆的蛋白质含量略有增加,其它品种的蛋白质含量均降低;除冀黄13号和早熟18号大豆外,其它品种的脂肪含量略有增加。更多还原

【Abstract】 Field experiment was conducted to study acetochlor effects on the growth,yield and quality of 9 soybean varieties from Huanghuai area.The results showed that the pods per plant,the numbers of seeds per plant,the seeds weight per plant and yield of the soybean were lower than that of hand-weeding plot after soil treatment of acetochlor.Different soybean varrieties had different sensibility.The application rate of(2 250 mL/hm~2) in soybean field had lighter influence on the growth of seedling and yield of Jiduo 7 and Wuxing 1 soybeans.The protein content of soybeans except Zhongzuo 011 is lower,the fat content of soybeans except Jihuang 13 and Zaoshu 18 is lightly higher than that of hand-weeding plot in acetochlor treatment.更多还原
