基于强酸富硒土壤的稻米富硒力探析
Study on Selenium Enrichment Capacity of Rice Based on Strong Acid Selenium Rich Soil
摘要
Abstract
To effectively exploit valuable selenium-rich soil resources,promote the development of selenium-rich rice industries,maximize the functional role of selenium in rice,and improve public health,this study selected 27 rice lines as experimental materials and conducted field trials in strongly acidic soil with rich organic matter and available potassium.The results showed that the selenium content of the produced rice was at a relatively low level,ranging from 0.0086 to 0.0247 mg/kg,with an average of 0.0153 mg/kg,a coefficient of variation of 0.258,and a maximum/minimum ratio as high as 2.86.The selenium enrichment coefficients of the rice lines exhibited highly significant differences due to genotype variations,and were generally low,ranging only from 0.0169 to 0.0484,with an average of 0.0299.The average selenium content in rice was only 61.2%of the national average,significantly lower than that in other selenium-rich rice-growing regions.All tested rice lines exhibited selenium deficiency,which is relatively rare in similar studies.This indicates that,in addition to rice genotype,soil properties also have a considerable influence on the selenium enrichment capacity of rice.Therefore,attention should be paid to the reshaping effect of spatiotemporal ecological changes on rice selenium enrichment.关键词
