Abstract
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.关键词
