农田杂草种类和分布的调查研究对制订综合除草措施,开发利用植物资源和盘点基因库都是重要的.九年调查,辽宁省杂草(维管束植物)83科359属756种。全省划分六个杂草分布区:1.辽东湿润山区;2.半岛半湿润丘陵区;3.西北半干旱风沙区;4.辽河上中游半湿润低丘平原区;5.辽河口及滨海湿润、半湿润平原区;6.辽西半湿润半干旱山地丘陵区。描述了各区自然条件和杂草种类,讨论了杂草分布规律,提出78种主要防治对象及杂草利用的建议。
Investigation and study on the types and distribution of weeds in farmland are important for the development of comprehensive herbicidal measures, development and utilization of plant resources and inventory of gene pools. Nine years of investigation, there are 756 species of 359 genera in 83 families of weeds (vascular plants) in Liaoning Province. The province is divided into six weed distribution areas: 1. Liaodong humid mountain area; 2. Peninsula semi-humid hilly area; 3. Northwest semi-arid windy sand area; 4. Liaohe River upper mid-humid semi-humid hilly plain; 5. Liaohekou and Marina Humid, semi-humid plain area; 6. Liaoxi semi-humid semi-arid mountain hilly area. Described the natural conditions and weed species in each area, weed distribution was discussed, and 78 kinds of main control objects and weeds were put forward.
