贵州大方辣椒种植基地生态地质环境分析

Ecological geology environment of pepper planting base in Dafang country of Guizhou province

为了扩大贵州大方辣椒规模化种植,从生态地质环境角度对贵州大方辣椒种植基地进行综合分析,结果发现:(1)大方县辣椒种植基地主要分布在三叠系的嘉陵江组(或永宁镇组)、关岭组、飞仙关组以及侏罗系的下沙溪庙组至上沙溪庙组及自留井组等地层的出露区,且三叠系的关岭组出露区较为适宜种植辣椒,而三叠系的嘉陵江组(或永宁镇组)和侏罗系出露区为辣椒种植适宜区。(2)贵州大方县的辣椒种植基地土壤中Mg、Al、K、Fe、Co、Cu、Zn和Mn等元素较为富集,能为辣椒生长提供充足的矿质营养元素来源。(3)大方县辣椒种植适合区主要有兴隆-八堡、长石-三元和果瓦-三元狭长带、达溪-核桃-响水-竹园-双山-文闵片区和羊场-黄泥塘-理化-鸡场-马场片区。

In order to increase the pepper planting scale in Dafang country of Guizhou province, this paper comprehensive analyzed the pepper planting base in Dafang Country from the view of ecological geology environment. The results showed that,（1） The main strata related to the planting environment distributed in the planting base were the Triassic Jialingjing Formation（Yongningzhen Formation）, Guanlingzu Group, Feixianguan Formation and the Jurassic System Lower Shaximiao Formation to Upper Shaximiao Formation, Ziliujing Formation, etc. Additionally, the Triassic Guanlingzu Group was more suitable to planting pepper and the Triassic Jialingjing Formation（Yongningzhen Formation）and the Jurassic System was suitable to planting pepper.（2） In the pepper planting soil in Dafang county, Mg, Al, K, Fe,Co, Cu, Zn and Mn elements are enriched, these could provide enough mineral elements for the pepper growth.（3） The suitable areas for planting pepper in Dafang country were the zone of Xilong to Babao, Changshi to Sanyuan and Guowan to Sanyuan, the area of Daxi, Hetao, Xiangshui, Zuyuan, Shuangshan and Wenmin, and the area of Yangchang, Huangnitang,Lihua, Jichang and Machang.
