摘要
通过对徐州市林场侧柏人工纯林林下植被进行抽样调查,选取形成林火地面易燃物的主要杂草一年蓬、野燕麦为研究对象,用农达(草甘膦异丙胺盐41%水剂)、MCPA(2甲4氯钠盐13%水剂)、精禾草克(精喹禾灵5%乳油)3种防除效率较高的除草剂进行试验。结果表明,农达和MCPA不同浓度混合溶液具很好的防除效果。从生态环境、防除效果和经济成本等因素综合考虑,200倍农达稀释液与200倍MPCA稀释液的混合液对一年蓬和野燕麦防除效果最佳,可应用在森林防火隔离带的建设中。
Erigeron annuus and Avena fatua Linn, the main flammable weeds on the ground were selected by a sampling survey of undergrowth vegetation of artificial pure Platycladus orietrtalis forest in Xuzhou Forest Farm, and the control effect of glyphosate （glyphosate-isopropylammonium 41% aqueous solution）, MCPA （2-Methyl-4-chlorophenoxyacetic acid 13% aqueous solution）, quizalofop-P-ethyl （5% EC） was studied. The resuhs showed that the mixture of glyphosate and MCPA had great control effects on the weeds. Furthermore, the control effect of the mixture of glyphosate （200 × ） and MPCA （200 ×） was the best and could be applied in the construction of forest firebreak.
