摘要: 在福建隽永天香茶业公司茶洋有机茶基地研究了茶园间作不同绿肥对假眼小绿叶蝉及其天敌缨小蜂的影响。结果表明,不同间作处理茶园假眼小绿叶蝉虫口数量差异显著(F=3.15,P<0.05),缨小蜂虫口数量差异极显著(F=4.22,P<0.01)。间作铺地木蓝+罗顿豆茶园,假眼小绿叶蝉虫口数量最高1035头,间作铺地木蓝+猪屎豆茶园,假眼小绿叶蝉的虫口数量最低378头;间作白三叶草+圆叶决明茶园,叶蝉天敌缨小蜂的虫口数量最高263头,缨小蜂虫口数量比空白对照提高了61.98%,茶园间作绿肥显著提高了天敌缨小蜂的种群数量。不同间作处理茶园假眼小绿叶蝉与天敌缨小蜂均呈显著的正相关。间作白三叶草+圆叶决明,茶园平均益害比最高为0.56,对照茶园最低为0.18。

Abstract: The effect of intercropping different green manures in tea plantations on the small green leafhopper (SGL) and its egg parasitoids were investigated in Fu'an, Fujian Province from 2010 to 2011. The results showed that intercropping different green manures showed significant influence on both the SGL populations (F=3.15, P<0.05) and the mymarids (F=4.22, P<0.01). The SGL population in tea plantations intercropped with Indigofera spicata Forssk+Lotononis bainesii Baker were the highest (1035), while in tea plantations intercropped with Indigofera spicata+Crotalaria pallida Ait., the population was the lowest (378). Intercropping green manure did not change the temporal population dynamics of SGL. The largest populations (263) of the mymarids were observed in tea plantations intercropped with Trifolium repens Linn.+Chamaecrista rotundifolia, which was 61.98% higher than in the CK, indicating that intercropping with green manure can significantly increase the mymarids population. The SGL and its egg parasitoids populations showed significantly positive correlations within all the five tea plantations. The highest ratio of natural enemies to pests (0.56) was achieved in tea plantations intercropped with T. repens+C. rotundifolia, which contrasted to the ratio of 0.18 in the CK.
