浙江省富阳县场口镇现有1454亩高山茶园,1991年茶叶总产量18.16吨,产值22.7万元,平均亩产量为12.5kg,亩产值156.10元。导致这些高山茶园产量低、效益差的主要原因:(1)茶园立地基础差,一般梯高1.50～2.00m,梯面宽度1.50～1.70m,土地利用率低,耕作层浅,土壤质地差,不能有效地蓄水保肥,每当夏秋之交雨量集中季节,水土流失严重,影响茶树正常生长。(2)气温低,昼夜温差大,平均气温都明显低于平地茶园3～5℃,每年的冬季和早春都要受到冰霜侵袭,因
Field town of Fuyang County, Zhejiang Province, existing 1454 acres of mountain tea plantations, tea production in 1991 18.16 tons, the output value of 227,000 yuan, the average yield per mu 12.5kg, mu 15.610 yuan. The main reasons causing low yield and poor efficiency in these alpine tea farms are as follows: (1) The foundation of the tea plantations is poor, generally 1.50 ~ 2.00m in height, 1.50-1.70m in width, with low land utilization, shallow tillage, poor soil texture, Can not effectively water and fertilizer, whenever the summertime fall rainfall concentrated season, serious soil erosion, affecting the normal growth of tea. (2) low temperature, large temperature difference between day and night, the average temperature is significantly lower than the flat tea garden 3 ~ 5 ℃, winter and early spring each year to be frost invasion, because
