摘要:
4,8-二羟基-1-四氢萘酮(4,8-DHT)为山核桃Carya cathayensis 外果皮化感物质,室内试验证实4,8-DHT 具有除草活性,但在林地中尚未得到验证。为明确4,8-DHT 对林地杂草的防除效果,依据《农药田间药效试验准则(一)中除草剂防除林地杂草》(GB/T 17980.48-2000)设置试验处理,对比分析不同浓度4,8-DHT 对杂草株数、覆盖率及株防效的影响。结果表明,36 mmol·L-1 4,8-DHT 药后8 d 对东京樱花Cerasus yedoensis 林地内的陌上菜Lindernia procumbens,拟鼠麴草Pseudognaphalium affine,车前Plantago asiatica,碎米荠Cardamine hirsuta,匙叶合冠鼠麴草Gnaphaliumpens ylvanicum 和紫薇Lagerstroemia indica 林地内的耳草Hedyotis auricularia 的株防效均达100%;不同施药方法对杂草的防除效果分析表明,4,8-DHT 对杂草种子萌发期的抑制作用强于幼苗期;对林地间杂草防除效果比较发现,36 mmol·L-1 4,8-DHT 对东京樱花和紫薇林地药后20 d 的杂草防除效果存在差异,这可能与林地环境因素和生物因素等有关。
Abstract:
During June and September 2018, experiments were conducted on effect of 4,8-dihydroxy-1-tetrahydronaphthone (4,8-DHT) made from allelochemical in the Carya cathayensis on herbicidal activity in Cerasus yedoensis and Lagerstroemia indica stands in Ningbo, Zhejiang province, according to Pesticide-Guidelines for the Field Efficacy Trials (Ι): Herbicides against weeds in forest Herbicide (GB/T 17980.48-2000). The results showed that 8 days after treatment of 36 mmol/L of 4,8-DHT, Lindernia procumbens, Gnaphalium affine, Plantago asiatica, Cardamine hirsuta, Gnaphalium pensylvanicum in C.yedoensis stand could be effectively controlled, and Hedyotis auricularia in L. indica stand, with the control effect of 100%. Different concentration of 4,8-DHT sprayed at different time indicated that it had better effect at weed seed germination. Comparing the weed control effect between different stands, it was found that the weed control effect of 36 mmol/L of 4,8-DHT was different in C. yedoensis and L. indica stands.
