摘要
宁波地处浙江省东部沿海，属于草坪气候生态区中的第Ⅷ气候带，即温暖潮湿带。近几年来，随着宁波城市绿化的高速发展，草坪种植面积达660多公顷。据不完全统计，马尼拉约占80．7％；高羊茅等冷季型草约占13．6％；狗牙根约占2．3％；混合草坪约占1．4％；其他地被植物（麦冬草、马蹄金等）约占2％。比例显示，暖季型草是构成宁泼城市绿地的主要草种。其中杂草一直是侵害草坪正常生长的潜在因素，对其科学预防显得日趋重要。本文对杂草的品种、发生季节、防除技术等进行阐述，重点介绍化学除草剂的使用技术。
Ningbo is located in the eastern coastal area of Zhejiang Province, which is in the VIII climatic section of the lawn climatic ecological zones, namely, warm and moist belt. In the last few years, with the rapid development of Ningbo city greenery, the ground area of the lawn cultivation amounts to more than 10,000 acres. According to incomplete statis- tics, Manila approximately composes 80.7% ; Yang Mao is about 13.6% ; Dog Teeth is about 2.3% ; mixed lawn is about 1,4% ; other cover plants （for example： Mai Dong grass, the HoMe＇s Hoof, etc. ） are about 2%. The proportion indi- cates that warm - type green grass is the major grass to plant in Ningbo city. And weeds have been the potential factors vio- lating lawn＇ s normal growth, so scientific prevention is increasingly important. This paper elaborates on the weed species, occurring season, prevention and cleaning technical measures, while focuses on the use of chemical herbicides technology.
