摘　　要：在青田县章旦乡农业观光园进行了套种白三叶（Trifolium repens）、常夏石竹（Dianthus plumarius）、二月蓝（Orychophragmus violaceus）3种果花套种小区对比试验,并对3种套种模式的生态效益进行了分析,结果表明：果园套种花卉和套种绿肥的生态效益相近,套种区与清耕区相比,在夏季可使地下15 cm处的土壤温度平均降低1.8℃以上,在春季可使土壤温度平均提高1.9℃以上;提高土壤含水量7.5%~21.7%;果园土壤有机质和速效N、P、K分别提高了67.9%~113.2%、12.8%~125.6%、5.7%~22.8%和18.8%~37.5%;土壤孔隙度增加了11.9%~12.9%,改良了土壤的理化性质。Experiment was conducted on interplanting Trifolium repens,Dianthus plumarius and Orychophragmus violaceus at peach garden in Zhangdan,Qingtian,Zhejiang province.Analysis on eco-efficiency of interplanting showed that it had similar eco-efficiency.Compared with no interplanting,interplanting could decrease temperature of 1.8℃ in the soil under 15cm in the summer,and increase 1.9℃ in the spring,increase soil moisture of 7.5%-21.7% in the soil,increase organic matter,available nitrogen,phosphorus,potassium of 67.9%-113.2%,12.8-125.6%,5.7%-22.8%,18.8%-37.5%,and increase soil porosity of 11.9%-12.9%.
