Effect of applying different herbicides in Xanthoceras sorbifolia Bunge.garden

对9%莎草净、240 g/L果尔乙氧氟草醚、108 g/L高效氟吡甲禾灵、25%侨虎硝磺秀去津、250 g/L氟磺胺草醚、10.8%精喹禾灵6种除草剂在文冠果林园的除草效果进行比较试验。结果表明,以每666.7 m 2喷施240 g/L果尔乙氧氟草醚50 mL、25%侨虎硝磺秀去津200 mL、250 g/L氟磺胺草醚100 mL、10.8%精喹禾灵40 mL对杂草地上部分有不同程度的影响。240 g/L果尔乙氧氟草醚50 mL、25%侨虎硝磺秀去津200 mL、250 g/L氟磺胺草醚100 mL对文冠果叶片有一定影响。250 g/L氟磺胺草醚100 mL+10.8%精喹禾灵40 mL对杂草的消除实现了全覆盖,但对文冠果的叶片影响较大。实际操作中,须注意避开树体喷施。

The effects of 9%Cypermethrin,240 g/L Oxyfluorfen,108 g/L Haloxyfop-R-methyl,25%Nitrosulfone-Atrazin,250 g/L Fomesafen and 10.8%Quizalofop-p-ethyl in Xanthoceras sorbifolia garden were studied.The above ground parts of weeds were affected by 240 g/L Oxyfluorfen 50 mL,25%Nitrosulfone-Atrazin 200 mL,250 g/L Fomesafen 100 mL and 10.8%Quizalofop-p-ethyl 40 mL per 666.7m 2.It had certain effects on Xanthoceras sorbifolia leaves by 240 g/L Oxyfluorfen 50 mL,25%Nitrosulfone-Atrazin 200 mL,250 g/L Fomesafen 100 mL per 666.7m 2.All weeds had been eliminated by 250 g/L Fomesafen 100 mL and 10.8%Quizalofop-p-ethyl 40 mL per 666.7m 2.But the leaves of Xanthoceras sorbifolia Bunge were influenced seriously.Avoid trees when spraying herbicides.
