摘要
3年的田间试验初步表明:在台湾青枣园套种热研2号柱花草、圆叶决明、银叶山蚂蝗、野生铺地木兰、苕子等绿肥作物,能显著增加天敌昆虫的种群、数量;显著提高土壤的肥力水平,增加土壤微生物数量;提高青枣产量、降低生产成本。其中以热研2号柱花草效果最好。
The result of 3 years shows that the kinds and the number of controlling insects and the amount of the edaphon, the yield and soil fertility increase markedly in the garden intercropping Stylosanthes guianensis cv.Reyan 2, Chamaecrista routundifolia, Desmodium uncintum, lndigofera endecaphylla, Vicia villosa and so on ; the effect of Stylosanthes guianensis cv.Reyan 2 is the best.
