水分是土壤肥力的要素,是茶树生长的首要条件。福建茶区多为红壤,肥力不高,水分状况不良,如何充分满足茶树对水分的需要,是茶树栽培研究者的重要任务。现将我所几年来的研究观察综合整理如下。一、自然降水与土壤含水量:茶园土壤水分的来源主要靠自然降水。本省茶区降水量以西北部多,东南部少,年降水量1,200～2,000毫米。常年三月至六月中小雨和阴雨连绵的雨日多,降水量达800～900毫米,占年降水量的48～50％,每月平均200毫米以上,气温15～25℃,土壤含水量为27～53％,属稳定适合范围。七月至九月降水量600毫米左右,占年降水量的35％左右,以
Water is an element of soil fertility and is the primary condition for the growth of tea trees. Fujian tea is mostly red soil, fertility is not high, poor water conditions, how to fully meet the needs of tea tree moisture, tea cultivation is an important task for researchers. Now my years of research observation consolidated as follows. First, the natural precipitation and soil moisture content: the source of the tea plantation soil moisture mainly by natural precipitation. Precipitation in tea province in the northwest of more, less in the southeast, annual rainfall of 1,200 ~ 2,000 mm. Perennial rainy and rainy rains occur frequently from March to June, with precipitation reaching 800-900 mm, accounting for 48-50% of the annual rainfall, with an average monthly temperature of over 200 mm and temperature of 15-25 ° C. The soil moisture content 27 ~ 53%, is a stable suitable range. July to September precipitation is about 600 mm, accounting for about 35% of annual precipitation
