摘要
对18个越冬大棚番茄定植初期番茄黄化曲叶病病株和其中14个大棚内烟粉虱进行了调查和抽样技术研究,以明确番茄黄化曲叶病病株及传毒介体烟粉虱的空间分布型。研究结果表明,番茄黄化曲叶病病株和烟粉虱在田间的空间分布型一致,均呈聚集分布。Iwao的m*-m模型分别为:m*=-0.209060+1.3659m和m*=-0.299134+1.4171m。同时得出番茄黄化曲叶病的最适理论抽样公式为n=t2/D2(0.79094/m+0.3659);烟粉虱的最适理论抽样数公式为:n=t2/D2(0.79848/m+0.4171)。
The infection status of Tomato leaf curl virus in the early period of tomato planting in 18 winter greenhouses were studied,and the sampling survey of Bemisia tabaci was also conducted in 14 greenhouses.The results indicated that the spatial distribution patterns of Tomato leaf curl virus which was distributed as aggregation distribution was consistent to that of Bemisia tabaci.The Iwao m*-m models of the spatial distribution patterns of Tomato leaf curl virus and Bemisia tabaci were as follows: m*=-0.209060+1.3659m and m*=-0.299134+1.4171m.The sampling equation of tomato leaf curl virus disease and Bemisia tabaci were best fitted n=t2/D2(0.79094/m+0.3659) and n=t2/D2(0.79848/m+0.4171),respectively.
