为寻求喀斯特地区农产品低劣的根源,通过调查和采样测试对比研究了贵州碳酸盐岩和非碳酸盐岩地质环境和农作物产品质量的差异.结果表明:(1)非碳酸盐岩的微量元素含量为10.894 2×10~(-3),而碳酸岩的为35.322 7×10~(-4);非碳酸盐岩地区耕作土中有效态微量元素含量为3.260 5×10~(-4),碳酸盐岩分布区的耕作土仅为1.014×10~(-4),彼此相差3倍;(2)优质农作物多产于非碳酸盐岩地区,随机调查贵州省内38个优质水稻产地,有33个位于非碳酸盐岩地区,仅有5个在碳酸盐岩区.茶叶、马铃薯、西瓜等也有此类规律.由此认为,喀斯特环境缺乏多种矿物营养元素,是形成其农作物质量低下的根本原因,也是贵州喀斯特农业生态环境脆弱的内在原因.

The karst environment takes up 61.9% in area in Guizhou province, which leads to weak environment and backward economy. Contrastive studies on element content of rock, soil and agricultural production in carbonate rock area and non-carbonate rock area are made in order to find factors leading to low output and poor quality of agricultural products in karst area. The study shows that carbonate rock lacks nutrient elements with the trace element content in carbonate rock is only 35.322 7×10~(-4) but the trace element content in clastic rock is up to 10.894 21×10~(-3). The effective element content in cultivated soil delivered from carbonate rock is low to 1.014×10~(-4) but up to 3.260 5×10~(-4) in cultivate soil delivered from clastic rock. The effective element content and total element content in cultivated soil delivered from clastic rock are 3 times higher than that from carbonate rock. High quality agriculture products such as rice, potato and tea mainly produced in non-carbonate area. And it is believed the low output and quality of products is resulted from the above-mentioned low trace element content and poor agriculture environment.
