- Investigation into Soil Selenium Distribution in Farmland of Bazhong
- Keywords:

- 摘要:
- 以川东北巴中市为例，采用实地采样法和室内测定法，对土壤Se含量及其分布做了研究，以促进其现代农业的发展，合理选择优势作物。结果表明：不同土壤类型Se含量：黄棕壤 > 黄壤 > 紫色土壤。黄壤不同土地利用类型Se含量：其他用地 > 农田 > 蔬菜地；黄棕壤不同土地利用类型Se含量：蔬菜地 > 其他用地 > 林地 > 农田 > 旱地 > 果园地；紫色土壤不同土地利用类型Se含量：农田 > 果园地 > 旱地 > 蔬菜地 > 其他用地。黄壤不同耕作制度类型Se含量：旱作地 > 水耕地；黄棕壤不同耕作制度类型Se含量：水耕地 > 旱作地 > 水旱地；紫色土壤不同耕作制度类型Se含量：水旱地 > 旱作地。不同地域土壤剖面中Se元素含量：通江县 > 南江县 > 巴州区 > 平昌县。巴中市Se含量平均值为0.165 μg/g，低于全国平均值。四个富硒产业带分别为：通江县富硒马铃薯产业带；南江县富硒金银花产业带；南江县富硒蔬菜产业带；南江县富硒茶叶产业带。马铃薯、金银花、茶叶均为巴中的富硒优势作物。
- Abstract:
- We took Bazhong county located in the northeast of Sichuan Province as example and carried out the research on the content and distribution of soil selenium by using on-site sampling and laboratory analysis testing methods to promote the reasonable selection of dominant crop and the modern agriculture development. The results show that the contents of soil selenium varied according to the soil types, land utilization types, and soil tillage systems. The contents of Selenium in different soil types decrease in the order of yellow brown soil > loess soil > purple soil. The contents of selenium in different land utilization types based on loess soil are other land use > farmland > vegetable land. The contents of selenium in different land utilization types based on yellow brown soil are vegetable land > other land use > forest land > farmland > dry land > orchard land. The contents of selenium in different land utilization types based on purple soil are farmland > orchard land > dry land > vegetable land > other land use. The contents of selenium in different soil tillage system based on loess soil are dry farming land > water irrigation land. The contents of selenium in different soil tillage systems based on yellow brown soil are water irrigation land > dry farming land > dry-wet land. The contents of Selenium in different soil tillage systems based on purple soil are dry-wet land > dry farming land. The contents of selenium in soil profiles are Tongjiang > Nanjiang > Bazhou > Pingchang. The Se content in Bazhong is 0.165 μg/g which is lower than the national average value. The potatoes industial belt in Tongjiang, the honeysuckle industrial belt in Nanjiang, the vegetables industrial belt in Nanjiang, and the tea industrial belt in Nanjiang are the four selenium-rich industrial belts. The potato, the honeysuckle and the tea are the selenium-rich dominant crops in Bazhong.
