【摘要】 用4种除草剂对大豆进行播后苗前或苗后处理,研究除草剂对大豆生长发育及产量和品质的影响。结果表明:喷施土壤处理剂乙草胺和噻吩磺隆后大豆株高增加,产量降低,但与对照无显著差异;喷施噻吩磺隆后大豆蛋白质含量提高。喷施茎叶处理剂乙羧氟草醚和苯达松使大豆株高降低,产量下降,其中苯达松100ml/亩、200ml/亩,乙羧氟草醚60ml/亩(以上均为商品量)处理,其产量与对照间的差异达显著水平;喷施乙羧氟草醚后大豆脂肪含量提高。更多还原

【Abstract】 Field experiment was conducted to study four herbicides on soybean yield and quality.The results showed that the plant height of soybean was higher and the yield was lower than that of hand-weeding plot after soil treatment herbicides,acetochlor and thifensulfuron,sprayed and protein content of soybean was increased in thifensufuron treatment.Nevertheless both soybean height and yield is lower than that of hand-weeding plot after foliage treatment herbicides,fluoroglycofen and bentazon,sprayed and fat content of soybean was increased in fluoroglycofen treatment.更多还原
