摘要
通过分析茶树生长的气候、地形地貌、土壤、母岩条件及河南省鲁山县在这些方面优劣势,发现:(1)鲁山县气候上能够满足茶树生长,但应选择耐寒耐旱茶种;(2)中低山区和丘陵区理论上适宜种茶,但陡峭的地形、脆弱的生态环境、严重的水土流失和高海拔均不利于种茶;(3)酸性母岩和发育其上的酸性土利于种茶,非酸性母岩及发育其上的碱性土均不利于种茶;(4)网格状布点调查表明土壤厚度空间变化非常复杂,沟谷地区、平原地区、坡度较小地区和人为活动较弱地区的土层通常较厚,其他情况下土层通常较薄.在上述分析基础上,获得了鲁山县气候、地形地貌、土壤、母岩的宜茶区,通过叠加分析,得到鲁山县44.61%的中低山区和76.57%的丘陵区适宜栽培茶树,它们主要分布于中低山区和丘陵区中坡度较缓的坡面中下部和沟谷地带;平原区不适宜种茶.
We analyze the climate,topography,soil and parent rock conditions in growing of tea plants and the advantages or disadvantages of Lushan county in these fields. Lushan county can satisfy the growth of tea in the climate,but cold-tolerant and drought-tolerant tea should be selected. The middle and low mountainous areas and hills in Lushan county are theoretically suitable for planting tea,but steep terrain,fragile ecological environment,severe soil erosion and high altitude are not conducive to tea cultivation. The acid mother rocks and acidic soils are conducive to planting tea,but non-acid mother rocks and alkaline soils are not conducive to planting tea. The spatial variation of soil thickness is very complex which according to the investigation of grid-like distribution points.The soil layers in the valley areas,plain areas,areas with small slopes and areas with weaker human activities are usually ticker than other areas.Based on the above analysis,the suitable range of tea planting is identified by the overlay analysis. The results show that 44.61% of the range in the middle and low mountain areas and 76.57% of the range in the hilly areas are suitable for tea planting which mainly distributed in the middle and lower parts of the terrain and the valleys. We find it is not suitable for tea planting in the plain areas.
