亚热带丘陵茶园间种豆科牧草，有利于调节茶园土壤温度和水分状况，改善土壤动物和微生物的生存环境，为茶叶优质高产奠定基础。在连续5年间种白三叶草的幼年茶园和其相临的清耕茶园进行土壤分析和田间调查，系统研究间种白三叶草对亚热带丘陵茶园土壤生态系统的影响。结果表明，和清耕茶园相比．间种白三叶草茶园土壤孔隙度高4．4％．有机质、水解氮和有效磷含量高24．1％，38．2％和16．2％，提高了表层土壤（0～20cm）和春茶采摘期（4—6月）的土壤水分含量，延缓并缩短了高温和干旱时间，营造了有利于蚯蚓生长发育的土壤环境，增加了土壤中有机碳含量和微生物量碳、氮、磷。在亚热带丘陵幼年...

Effects of interplanting Trifolium repens in tea plantation were studied by the way of comparison in soil physical and chemical properties, temperatures, moisture, soil animal （earthworm） and the microorganism amount during the past consistent five years. It was found that the interplantation can not only improved soil ecology by developing soil physical properties and soil fertility, increasing the soil water content which was helpful to regulate the period of drought. Meanwhile, but also can enrich the soil organic C, SMB-C, and the proport...
