我国江南各省山地红黄壤的土壤化学性质基本上能满足茶树生长的要求,因此这个地区早就成为我国发展茶叶生产的重要基地。但是某些地区的红黄壤由于石灰岩(以及石灰性反应的岩石,下同)的影响,不同程度地使土壤化学性质不利于茶树生长,使这些地方的茶树生长不良甚至死亡。在我省 The chemical properties of the mountainous red and yellow soil in Jiangnan provinces basically meet the requirements of tea tree growth. Therefore, this area has long been an important base for the development of tea production in China. However, due to the influence of limestone (and limestone-reacting rocks, the same below), red and yellow earth in some areas make the chemical properties of the soil unfavorable to the growth of tea plants to varying degrees, so that the tea trees in these areas grow poorly and even die. In our province
