CULTIVATION METHOD OF LEAFY VEGETABLES, INCREASING SELENIUM AND GERMANIUM CONTENTS AND LEAFY VEGETABLES CONTAINING INCREASED SELENIUM AND GERMANIUM CONTENTS

摘要

PURPOSE: Provided are a method of increasing selenium and germanium contents in leafy vegetable production by using fertilizing solution containing a large amount of sodium selenate and germanium dioxide and leafy vegetables containing increased selenium and germanium contents produced thereby. Therefore, the leafy vegetables display increased antioxidation and growth rates. CONSTITUTION: A method for cultivating leafy vegetables is characterized by using fertilizing solution which contains 2-4ppm of selenium and 2-4ppm of germanium and has a pH value of pH 5.5-6.5. The selenium is selected from sodium selenate or selenate, and the germanium is, in particular, germanium dioxide. The leafy vegetables are treated with the fertilizing solution for 5-7 days right before the harvest thereof.
