富硒苹果园根系不同分区土壤硒与营养元素变化特征研究
Variation characteristics of soil selenium and nutrient elements in different root zones of selenium-rich apple orchards
摘要
Abstract
In order to explore the consumption of soil selenium in selenium-rich apple orchards,six typical apple orchards were used as the research objects in Hebei Province,and the soil selenium content,soil organic matter,pH value,and selenium content in fruits were analyzed,so as to clarify the soil characteristics of selenium-rich apple orchards and their impacts on the selenium accumulation in fruits.The results showed that:The soil in apple orchard of Shunping County,Baoding City was selenium-enriched,with a selenium content of 0.484 mg/kg,which met the standard of selenium-rich soil.There was an extremely significant positive correlation(r=0.840**)between the selenium content in its fruits(57.92 μg/kg)and the available selenium in the soil.The soil selenium content had significantly positive correlation with organic matter,available potassium,and available phosphorus(r=0.531**,0.446**,0.338**),and had significantly negative correlated with the pH value(r=-0.283*).In the horizontal direction of the apple root system,the soil selenium content,organic matter,and available phosphorus all decreased with the increase of the distance from the main trunk,while the changing trends of available potassium and pH value were opposite to them;in the vertical direction,each indicator showed a decreasing trend with the increase of the soil layer depth.关键词
