通过几年的试验研究,筛选几种化学除草剂和其最佳剂量;针对大行距针叶树圃地,采用草甘膦防除冰草,同时配伍2,4-D丁酯兼杀其它阔叶杂草;针对小行距针阔叶树苗圃地,采用盖草能或者禾草克防除冰草等禾本科杂草,同时配伍果尔兼杀其它阔叶杂草;土壤处理剂采用氟乐灵作杂草发芽前处理。 Through several years of experimental research, several chemical herbicides and their optimum dosage were screened. For the large-scale coniferous tree nurseries, glyphosate was used to control Agropyron, while 2,4-D butyl and other broad-leaved weeds ; For small row coniferous and broadleaf tree nursery, the use of cover grass or grass grams of grass to prevent weeds and other grass weeds, and also compatible with fruit and kill other broadleaf weeds; soil treatment with trifluralin as weed before germination deal with.
