研究了新垦幼龄茶园套种4种经济绿肥对茶园生态环境所产生的效应,结果表明:茶园套种经济绿肥在高温期能平均降低地表温度6.64℃；0～ 10、10 ～20、20～30 cm土层温度分别降低5.54、2.95、1.97℃；0～30 cm土层含水量平均提高1.93％；土壤速效养分平均提高为:有机质2.68 g/kg、全氮0.09 g/kg、碱解氮27.81 mg/kg、速效磷2.92 mg/kg、速效钾5.13mg/kg；减少茶园泥沙流失量平均为:坡面41.75％、台面24.64％.%The effects of interplanting 4 kinds of economic green manure on the ecological environment of newly - reclaimed young tea plantation were studied. The results showed that interplanting economic green manure in newly - reclaimed young tea plantation could averagely reduce the earth's surface temperature by 6.64 ℃ in high temperature period. The temperature of0~10cm, 10~20 cm and 20 ~ 30 cm deep soil layer was decreased by 5.54 ℃, 2.95 ℃, and 1.97 ℃, respectively. The moisture content in 0 - 30 cm deep soil layer was averagely enhanced by 1.93%. The content of available nutrients in the soil was averagely enhanced as follows: organic matter by 2.68 g/kg, total nitrogen by 0.09 g/kg, alkali - hydrolyzable nitrogen by 27.81 mg/kg, available phosphorus by 2.92 mg/kg and rapidly available potassium by 5.13 mg/kg. The average soil and sand loss of sloping surface and broad in tea garden was reduced by 41.75% and 24.64% respectively.
