河南省固始县茶区茶树生长的自然地理环境分析

文章通过对河南省固始县茶区的气候、地形、土壤等自然条件进行研究。结果发现：本区平均气温与江南、华南茶区相比偏低,年降水量处于国内茶区中等水平,导致茶园春季开园迟,轮采次数少,单产量低和品质优的特点,降水量的季节分配与茶树生长需求基本相符;区内茶园海拔较低,西部茶园坡度稍大,但开发成梯地的形式,有利于水土保持;茶区的黄棕...

An Analysis of Geographical Environment of Tea Growth in Tea Plantations of Gushi County in Henan Province

By studing the climate,topography,soil of Gushi County in Henan Province,we have obtained the following conclusion.The Average temperature is lower than tea area in the south of the Yangtze River and the southern part of China.The annual precipitation in this region is moderate and monthly precipitation is comfort to the physiological requirements of the tea plants.These lead to the delay of beginning the plucking of the tea garden,the reduction of times of cycle plucking and the low per unit area yield of the tea,which results in the advance in quality of tea to a certain extent.The altitude of the tea region is relatively low and the western slope of tea garden is slightly larger,but is developed into ladders in the form for soil and water conservation.The physicochemical property of the soil in this region is well with abundant nourishment,but it lacks phosphorus because the content of total phosphorus and rapidly available phosphorus is low,so it should be manured additional phosphate fertilizer.
