“水是农业的命脈。”搞好茶园水土保持,是茶叶生产中基本的环节,是建立高稳产茶园的重要条件。经试验和生产实践证明,在茶园梯层内侧设置横沟(竹节沟)蓄水系统,加强雨水停蓄时间,缓和降雨流速,不使同层雨水外流,是茶园水土保持的一种好办法。它不但做法简单,而且效果很好。我们在坡度20度左右的茶园定区观测结果:每亩梯级茶园中有横沟蓄水的,一次可贮水15290公斤(不包括渗透水量),相当于23毫米的降雨量,水土流失临界时降雨量可达30毫米左右;没有横沟蓄水
“Water is the lifeblood of agriculture.” Improving the soil and water conservation of tea gardens is a basic link in tea production and an important condition for establishing a tea garden of high and stable yield. The experiment and production practice have proved that it is a good way to maintain soil and water of the tea plantation by setting horizontal water ditch (bamboo ditch) water storage system in the inside of the tea plantation ladder, strengthening rainwater retention time, easing the rainfall velocity, . It is not only simple, but also works well. We observed about 20-degree gradient in the tea garden area: There was a horizontal ditch water storage in the cascade of tea in the cascade, which could store 15,290 kilograms of water (excluding permeable water) at a time, equivalent to 23 millimeters of rainfall. At the critical time of soil erosion Rainfall up to 30 millimeters; there is no lateral ditch water storage
