| 摘 要： | 作者评价了湖南丘陵桔园间种藿香蓟对桔树螨类和昆虫的影响。桔园间种藿香蓟、免耕蓄草能改善桔园的小生境,提高桔园夏季相对湿度和冬季温度,降低夏季树冠和土壤温度,创造一个有利于天敌生存的良好环境;能提供钝绥螨的交替食料和栖息、产卵场所;能控制柑桔全爪螨的秋季为害,减轻柑桔全爪螨的春季为害和柑桔潜叶蛾的为害,但加重了柑桔花蕾蛆和天牛类害虫的为害。能提高树体的抗旱和抗寒能力,改善土壤结构,增加土壤肥力,提高柑桔品质和产量,降低防治费用。文中还评价了防治策略、灌溉方式和藿香蓟的长势等因素对间种藿香蓟控制柑桔全爪螨的作用。

| Abstract: | The effect of Ageratum conyzoides as the ground vegetation interplanted in hilly citrus orchard in Hunan Province on mite and insect populations was studied. The habitat of citrus orchard could be improved by this till - less interplantation condition, the RH in summer and temperature in winter were increased, and the summer temperature in canopy and soil were decreased, which were beneficial to the survival of natural enemies. The vegetation could provide alternative food and living and oviposition site for predatory mites,suppress the autumn damage and alleviate the spring damage of citrus red mite Parmychus ctiri(McGregor) .and also reduce the damage of citrus leaf -miner Phyllocmstis citrella (Stainton)in spring;while the damage of citrus flower midge Con-tarinia citri Barnes and longicorns were increased. It could enhance the tolerance of citrus to drought and cold,improve the soil structure and fertility,increase the quality and yield of citrus fruit, and reduce the cost of control. The effect of control tactics, irrigation system and growth situation of A. cunyzoides on the citrus red mite control by Ageratum interplantation were discussed. |
