Selenium-rich cadmium-reducing leaf fertilizer special for paddy

Abstract

The invention belongs to the technical field of a paddy planting fertilizer and specifically relates to a selenium-rich cadmium-reducing leaf fertilizer special for paddy. The selenium-rich cadmium-reducing leaf fertilizer special for paddy is composed of citric acid monohydrate, sodium selenite, urea, potassium chloride, monopotassium phosphate, soluble microelement compound, momordica grosvenori and herb of alligator alternanthera. The leaf fertilizer can increase the absorbing conversion rate of the paddy for selenium, has an excellent cadmium-impeding performance, is rich in nutrition and is easily absorbed.
