茶园发生干旱时,茶树的生长活动就会受到抑制。在高温缺水的情况下,会造成茶树呼吸作用的养分消耗超过光合作用的养分制造,使茶树新梢内有机质含量减少,结果茶叶的产量和品质都会大大降低。本场历年来秋旱都很严重,在7月间以及7月前后,经常有蒸发量超过降水量的情况。因此,茶园防旱就成为茶叶增产的关键问题之一。1958年夏,我们作了一个简单的灌溉与遮荫的防旱预备试验,分灌溉、灌溉遮荫、遮荫、对照4个处理,于四年生开始正式采摘的新茶园中进行。遮荫处
In the event of a drought in the tea plantation, the growth activity of the tea tree will be inhibited. Under the condition of high temperature and water shortage, the nutrients consumed by the respiration of the tea tree will be consumed more than the nutrients of photosynthesis, resulting in the decrease of the organic matter content in the shoot of the tea tree. As a result, the yield and quality of the tea leaf will be greatly reduced. In the past years, the autumn drought is very serious. In July and around July, there is often the case that the evaporation exceeds the precipitation. Therefore, the tea plantation drought has become one of the key issues of tea yield. In the summer of 1958, we made a simple drought preparedness experiment for irrigation and shading, which was divided into irrigation, irrigation shading, shading, and four treatments, and was carried out in the new tea plantation where the four-year-old people began to formally pick.
