Embodiment Construction
[0037] The present invention selects wild mountain jujube and mountain jujube growing in a good ecological environment, performs root application of solid selenium preparation and branch bud spraying of liquid selenium preparation before jujube germination and early stage of jujube bud growth, and uses jujube bud growth to The absorption and transformation of various elements in the preparation achieve the purpose of enriching jujube buds with selenium.
[0038] The invention adopts a composite selenium preparation containing selenium, iron, zinc, magnesium, calcium, molybdenum, boron, copper, manganese, nitrogen, phosphorus and potassium, and applies two methods of solid fertilization and liquid spraying. Ecological mountain jujube trees produce selenium-enriched jujube bud tea.
[0039] The invention carries out biological selenium enrichment through scientific mechanism and methods, and the selenium nutrient content of the selenium-enriched jujube bud reaches 230 micrograms / kg....
