我场地处粤北中部的丘陵山区,为石灰岩地带喀斯特地形,土壤属红黄壤。六一至七○年平均温度20.7℃,一月份平均气温11℃,霜期较短;年平均雨量2065.4毫米,而3—6月约占60%,年高温干旱出现在七、八月、七月平均气温28.3℃;表土温度最高达70℃,低温霜冻出现在一月底,最低温度-6℃。就常年来看,气温较高,雨量充沛,早期较短,适宜茶树生长。我们从五九年开始种茶,现在有茶园面积7614亩,其中:开采茶园5702亩,七四年产茶8074担,其中红碎茶5700多担,五大队培育丰产茶园9.25亩,七四年平均亩产茶青3992斤,其中:1.54亩的管道施肥茶园亩产达4766斤。本文就这片丰产茶园试验实践经过,谈几点粗浅的认识。
My field is located in the hilly mountainous area in the middle of northern Guangdong. It is a karst terrain in the limestone zone with red and yellow soils. The average temperature during June 1 to 70 was 20.7 ° C. The average temperature in January was 11 ° C with a short frost period. The average annual rainfall was 2065.4 mm, while it was about 60% in March-June. The annual temperature and drought occurred in July, August and July The average temperature of 28.3 ℃; topsoil temperature up to 70 ℃, low temperature frost appears at the end of January, the lowest temperature of -6 ℃. On a regular basis, the temperature is high, abundant rainfall, early short, suitable for tea growing. We have started to grow tea from the year of 1959. Now we have a total area of 7,614 mu of tea plantation, of which 5702 acres of tea plantation is exploited, 8074 dan of tea is produced in 1974, of which 5700 are red broken tea, and 9.25 mu are cultivated by the 5th Brigade The average yield per mu tea 3992 pounds, of which: 1.54 mu of fertilized tea garden fertilizer yield of 4766 pounds. This article on the practice of this high-yielding tea garden after, talk about a few superficial understanding.
