Evaluation of Soil Quality and Suitability of Green Selenium-rich and Germanium-rich Production Areas in Nanhua Area of Central Yunnan
摘要
Abstract
The study aimed to master the soil nutrients,soil environment,soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua of central Yunnan.Based on the 630 surface soil samples data obtained from the 1:250000 land quality geochemical survey in Nanhua of central Yunnan,the soil nutrients,soil environment,soil quality and soil environmental quality of green selenium-rich and germanium-rich production areas in Nanhua County were evaluated according to relevant national or industry standards.The results showed that soil nutrient content in the study area was medium-highly rich,with 37.19%of the soil having sufficient nutrients of the first and second grades,and 42.35%of the soil having sufficient nutrients of the third grade.The overall soil environment was good,with first-grade soil(risk-free)accounting for 80.19%,second-grade soil(risk-controllable)accounting for 19.41%,and third-grade soil(higher risk)accounting for only 0.40%.The comprehensive grade of soil quality was generally high-quality and good,and the proportion of first-grade(high-quality)and second-grade(good)soil reached 60.26%.The proportion of soil that meets the AA grade green selenium-rich production area standard was 2.78%,and the area was 63 km2.The proportion of soil that meets the AA grade green germanium-rich production area standard was 28.5%,and the area was 646 km2.The proportion of soil that meets the AA grade green selenium-rich germanium production area standard was 2.78%,and the area was 63 km2.The soil nutrients in the study area were relatively sufficient,the soil environment was generally good,and it had broad prospects for the development of green selenium-rich and germanium-rich foods.This study provided a scientific basis for the establishment of a green selenium-rich and germanium-rich planting and breeding experimental base and the development of green selenium-rich and germanium-rich agricultural and livestock products in central Yunnan,and contributed to the construction of ecological agriculture,local economic development and rural revitalization in Nanhua area,it also had a certain reference effect on the development of green agriculture and the land use planning in central Yunnan.关键词
