高尔夫球场不同功能区草地蛴螬虫口密度及迁移动态研究

摘要/Abstract

摘要： 对亚热带地区3家高尔夫球场不同功能区草地蛴螬虫口密度及迁移动态进行了研究。结果表明,3家球场球道和果岭区草地蛴螬虫口密度及迁移动态明显受干湿季节、地形(区域)及养护水平的影响。雨季高地形(长草高地和短草高地)蛴螬虫口密度是旱季同地形蛴螬虫口密度近1倍,是雨季凹地形蛴螬虫口密度近数倍,而雨季凹地形(长草凹地和短草凹地)虫口密度则与此相反;旱季和雨季高水平养护区(短草高地和短草凹地)蛴螬虫口密度分别略高于粗养护区(长草高地和长草凹地);果岭蛴螬虫口密度变化除Ⅰ区、Ⅱ区与球道区(长草高地和短草高地)相似外,Ⅲ区、Ⅳ区变化不明显,而且蛴螬数量很少。Ⅰ区、Ⅱ区占整个果岭区蛴螬总密度约90%;果岭4区之间发生一定程度的蛴螬迁移,但局限在相邻区内,3天内2家球场迁移率平均为41.09%,相隔区迁移率为0,蛴螬迁移能被隔离措施完全阻隔;漆标记和隔离试验表明,4区蛴螬虫口密度显著性差异是果岭外部蛴螬迁入的结果;旱季球道区蛴螬主要分布于地下较深土壤中(5～11cm),雨季向地表位移(2～5cm),其中长草高地和短草高地年均入土较深,长草凹地和短草凹地入土较浅;果岭区蛴螬年均入土深度为球道区的一半左右,周年在0.3～7cm之间土层活动,9～10月接近地表活动(0.3～1cm).

Abstract: Dynamic of moving and population of grubs in 3 golf courses under subtropics according to different areas of golf courses was reported.The results showed that dynamic of moving and population of grubs in fairway and green of 3 golf courses was affected by dry and rainy season,topography(or areas) and maintaining level.Grubs population for highland (rough highland and high fairway) in rainy season (5～9 months) were about one fold of witch for same topography in dry season(1～4,10～12 months) and severalfold for depressed land (rough depressed land and depressed fairway) in rainy season,it was in the reverse for depressed land in rainy season.Grubs population in high maintaining areas(high fairway and depressed fairway) for dry and rainy season was individually lightly high which of rough areas.Grubs population in green except grubs population in greenⅠ,Ⅱbeing similar to fairway,being not differed obviously that grubs population in greenⅢ,Ⅳ areas,and few amount of grubs in greenⅢ,Ⅳareas.Amount of grubs greenⅠ,Ⅱ made up 90% of total grubs population.Grubs in green among 4 areas moved certainly,but this behaviour only occur in border upon areas.Moving rate of grubs in border upon areas for 3 days was 41.09%,zero for apart areas,moving behaviour of grub in border upon areas could be stopped by artificial obstacle.Lacquer mark and isolating tests showed that difference of grubs population among green 4 areas was result of grubs moving from out of greenⅠ.Grub in fairway during dry season mainly lived in 5～11 cm soil under ground,2～5 cm soil under ground for rainy season,among them,grub living in soil under ground for rough highland and short grass highfairway were relatively deep,grubs living in soil under ground for rough depressed land and short grass depressed fairway were relatively shallow.The anniversary average depth of grubs living in green soil was a half of fairway,grubs in green soil for anniversary lived in 0.3～7 cm,living nearly in surface of the earth for 9～10 months(0.3～1 cm).
