金沙湾乡村俱乐部海滨雀稗草坪杂草及化学控制技术研究

 本研究于２００６－２００８年在江苏金沙湾乡村俱乐部进行，明确该球场有草坪杂草２９科９５种，其中禾本科１９种，莎草科３种，阔叶草２７科７３种。其中春季萌发的有５０种，秋季萌发的３６种，春、秋季都萌发的９种。建场初，杂草种类仍保留原生态系的痕迹，经过草坪管理特别是剪草及应用除草剂，杂草种类转为以草坪伴生杂草为优势种。田间杂草化学防除试验表明，砜嘧磺隆（Ｒｉｍｓｕｌｆｕｒｏｎ，ｎ ｛［（４，６-ｄｉｍｅｔｈｏｘｙ-２-ｐｙｒｉｍｉｄｉｎｙｌ）ａｍｉｎｏ］ｃａｒｂｏｎｙｌ｝-３-（ｅｔｈｙｌｓｕｌｆｏｎｙｌ）-２-ｐｙｒｉｄｉｎｅｓｕｌｆｏｎａｍｉｄｅ）０．０４５～０．０３０ｋｇａｉ／ｈｍ^２ 与嗪磺隆［Ｃｈｌｏｒｓｕｌｆｕｒｏｎ，１-２-ｃｈｌｏｒｏｐｈｅｎｙｌｓｕｌｆｏｎｙｌ-３-（４-ｍｅｔｈｏｘｙ-１，３，５-ｔｒｉａｚｉｎ-２-ｙｌ）ｕｒｅａ］０．０２００～０．０２２８ｋｇａｉ／ｈｍ^２ 混配秋季在海滨雀稗应用，药后６１和１１５ｄ，对禾草和阔叶草防效为６５．４％～９４．８％。氯吡嘧磺隆（Ｈａｌｏｓｕｌｆｕｒｏｎ ｍｅｔｈｙｌ，ｍｅｔｈｙｌ５-｛［（４，６-ｄｉｍｅｔｈｏｘｙ-２-ｐｙｒｉｍｉｄｉｎｙｌ）ａｍｉｎｏ］ｃａｒｂｏｎｙｌａｍｉｎｏｓｕｌｆｏｎｙｌ｝-３-ｃｈｌｏｒｏ-１-ｍｅｔｈｙ-ｌ １Ｈ-ｐｙｒａｚｏｌｅ-４-ｃａｒｂｏｘｙｌａｔｅ）０．０３７５～０．０５２５ｋｇａｉ／ｈｍ^２ 与砜嘧磺隆０．０４５～０．０３０ｋｇａｉ／ｈｍ２ 混配秋季在海滨雀稗应用，药后４９和１０３ｄ，对多年生黑麦草、一年生早熟禾防效为６９．４％～７１．２％。砜嘧磺隆０．０６ｋｇａｉ／ｈｍ^２、氯吡嘧磺隆０．０６７５ｋｇａｉ／ｈｍ^２ 及嗪磺隆０．０２２８ｋｇａｉ／ｈｍ^２对建植１年的海滨雀稗（品种：Ｓａｌａｍ）生长无影响或甚微，砜嘧磺隆０．１８ｋｇａｉ／ｈｍ^２ 药后２～４周对海滨雀稗有可见影响，直到药后３６周才恢复。

Weed species and their chemical control in Paspalum vaginatum cv. Salam at the Kingswan Countryside Club

This study was conducted at the Kingswan Countryside Club between 2006 and 2008 to determine the weed species,their growth habits and life cycles.The 95 weed species found included 19 grasses,3 sedges,and 73 broadleaved species from 29 families.Among them,50 species only germinated in spring,36 in the fall and the remainder in both spring and fall.During the first year of course establishment there were remnant traces of the original weed community present although more mat-forming weeds were present due to...
