摘要
[Objectives]This study was conducted to explore the effects of using fermented organic fertilizers such as cow manure on the activity of selenium in the soil.[Methods]The project team applied the organic fertilizer prepared by fermenting cow manure and other raw materials to activate selenium in the soil at two dragon fruit orchard bases in Shilong Town,Guiping City and Dingdang Town,Long an County,and carried out many years of experiments.[Results]The contents of available selenium in the two experimental orchards in Shilong Town and Dingdang Town increased by 10%and 5%,respectively,and the selenium contents in dragon fruit increased by 228.6%and 200.0%,respectively.[Conclusions]The application of fermented organic fertilizers such as cow manure can increase available selenium content in the soil,thereby increasing the selenium content of dragon fruit.
