Abstract

The invention discloses a composite fertilizer special for iodine-rich tea. The composite fertilizer is characterized by comprising decomposed chicken manure, plant ash, borax, ferrous sulphate, river mud more than five years, Chile nitre, sea-tangle, laver, citric acid dregs, ammonium phosphate, urea, peanut hull powder, and a water-retaining agent. By employing the composite fertilizer, the tea is exuberant in growth, strong in resistivity, and high in yield. The processed tea is excellent in color, smell, and taste; and the shelf life of the tea is prolonged. The tea adsorbs the iodine element from the fertilizer for a long period, so that the iodine content of the tea is higher than that of ordinary tea. The tea planted by using the composite fertilizer has an iodine content of 4.32+/-0.4 mg in every a kilogram of dried tea.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a special compound fertilizer for iodine-rich tea leaves. Background technique [0002] Iodine is one of the essential trace elements for the human body. Iodine is closely related to human health. Adults contain 20-50 mg of iodine, which is an element necessary to maintain the normal function of the thyroid gland. Goiter occurs when the body is deficient in iodine. So iodide can prevent and treat goiter. Tea drinks are known as "one of the three major beverages in the world". The chemical composition of tea is composed of 3.5-7.0% inorganic matter and 93-96.5% organic matter. There are about 27 inorganic mineral elements in tea, including phosphorus, Potassium, sulfur, magnesium, manganese, fluorine, aluminum, calcium, sodium, iron, copper, zinc, iodine, selenium, etc. Drinking tea can play a role in human health care, but the iodine content in general tea leaves is very l...
