海南番木瓜主产区土壤、植株硒含量及施硒效应研究

Study on the Selenium Content and Effects of Selenium Applicationon Payaya in Hainan Province

海南番木瓜土壤及植株硒含量的调查结果表明:海南主产区的番木瓜果园土壤普遍处于较低硒含量状态。采用叶面喷施并配合土施硒肥的方法,可以明显提高番木瓜植株及果实中的硒含量。

The results of the survey revealed that the natural selenium content is very low in major papaya producing area of Hainan province. The selenium content in papaya plant and fruit could be effectively increased by the application of selenium through leaf spray or soil application.
