为探究间作经济作物对重要茶虫黑刺粉虱种群数量和空间特征的影响、以便选择适宜的间作作物,遂选乌牛早品种的纯茶园、乌牛早分别与柑桔、杨梅和吊瓜间作茶园、以及安吉白茶与吊瓜间作茶园,2007年9月上旬-2008年12月下旬,每旬1次调查茶丛上、中、下层各虫态的粉虱数量,网捕茶梢近空的粉虱成虫。结果表明:(1)5类茶园的粉虱总个体数、以及茶丛上、中和下层粉虱个体数之间的差异均分别达到显著水平,以安吉白茶与吊瓜间作茶园的粉虱总数最多、纯茶园次之、乌牛早-吊瓜间作茶园最少;(2)间作吊瓜的2块茶园茶丛上层的粉虱数量明显减少;(3)以茶园粉虱总个体数、茶丛上、中和下层粉虱个体数为属性、5类茶园为实体的聚类分析表明,纯茶园、乌牛早-杨梅和乌牛早-柑桔间作茶园归为一类,乌牛早-吊瓜、安吉白茶-吊瓜间作茶园各为一类。分析认为:不同品种的茶树与间作作物合适的组合可抑制粉虱种群、不合适的组合会增进粉虱种群,间作还可改变粉虱数量的垂直分布。
In order to explore the effects of intercropping cash crops on the population and spatial characteristics of T. glauca in tea plantations, so as to select appropriate intercropping crops, Intercropping tea plantations, as well as Anji white tea and hanging melons for inter-tea plantations, early September 2007 - late December 2008, every ten days to investigate the tea in the upper, middle and lower levels of whiteflies in the insect population, Whitefly adults. The results showed that: (1) The total number of whitefly individuals in the five types of tea plantations, and the individual numbers of whiteflies in the upper, middle and lower layers of tea plantations reached significant levels respectively. The total number of whitefly in tea plantations (2) The number of whitefly in the top of two tea plantations with intercropping melon decreased significantly; (3) The total number of whitefly in tea plantation was significantly lower than that of tea plantation The results showed that pure tea plantations, Wanyao-Yangmei and Wuniuzao-Citrus intercropping tea gardens were classified into one category, and Wulianzao-hang Melon, Anji white tea - hanging melon tea garden for a class. The results showed that the suitable combination of tea tree and intercropping crop could restrain the population of whitefly, the improper combination could increase the population of whitefly, and the intercropping could change the vertical distribution of whitefly.
