| 摘 要： | 研究了南方红壤区紫花苜蓿田间杂草发生规律及除草剂防控的效果。结果表明:紫花苜蓿苗期及早期生长主要受到宝盖草危害,生长期主要杂草有猪殃殃、牛筋草、拌根草等,休眠期主要杂草为禾本科和莎草科杂草。除草剂阔除虽然对阔叶杂草有一定的效果,但对紫花苜蓿存在显著的危害。精禾草克乳剂和高效盖草能乳剂能显著抑制或灭杀禾本科杂草,但对阔叶杂草无作用。

| Abstract: | The occurrence regularity of the weeds and the effects of several herbicides in alfalfa field in south red soil region were studied.The results showed that alfalfa was mainly invaded by henbit at the seedling and early growth stage,invaded by cleavers,goose grass,bermudagrass and so on at the growth stage,invaded by gramineous weeds and sedge weeds at the dormancy stage.The results of herbicide effect showed that Kuochu had effect on broad-leaf weeds,but also did significantly harm to alfalfa.Jinghecaoke and Gaicaoneng could significantly control or kill gramineous weeds,but had no effect on broadleaf weeds. |
