摘要
近年来,大豆“症青”现象在黄淮海地区频繁发生且有逐年加重的趋势,严重威胁着大豆安全生产。大豆“症青”主要表现为大豆进入生长后期,结荚不鼓粒或瘪荚皱粒,叶片浓绿变厚,豆荚、叶片和茎秆等长期保持绿色,导致大豆源汇失衡,营养物质运输受阻,进而造成大豆减产。为了探明大豆“症青”的成因,综合有关学者和作者团队的研究结果,对可能导致大豆“症青”的多种生物和非生物因子进行了综合分析,包括温度、虫害、病毒等。作者认为点蜂缘蝽刺吸为害是导致大豆“症青”的关键因子,其他因子尚需进一步确认。为了降低大豆“症青”的发生,提出了针对大豆田点蜂缘蝽的综合防治措施。
In recent years,the phenomenon of remaining green and delaying maturity of soybean has occurred frequently in the Huang-Huai-Hai area,and has been increasing year by year,seriously threatening the safety of soybean production.The main manifestation of this phenomenon is that the pods are not bulging or wrinkled with thick green leaves,and pods,leaves,and stems remaining green for a long time at the late stage of soybean growth,leading to an imbalanced growth,an obstruction of nutrient transport,and a reduction in soybean production.In order to explore the causes of remaining green and delaying maturity of soybean,a comprehensive analysis was conducted on various biological and abiotic factors,including temperature,pests,viruses,etc.,based on the research results of relevant scholars and the author’s team.The damage caused by Riptortus pedestris is a key factor leading to the remaining green and delaying maturity of soybean,and other factors need to be further confirmed.In order to reduce the occurrence of this phenomenon,comprehensive control measures for R.pedestris in soybean field was proposed.
