Abstract

The invention belongs to the field of fertilizers for tea, and provides a special humic-acid-containing water-soluble solid fertilizer for Tieguanyin tea. The fertilizer comprises raw materials in percentage by weight as follows: 30%-35% of potassium humate, 25%-35% of urea, 10%-20% of diammonium phosphate, 5%-10% of potassium sulphate, 9%-15% of magnesium sulfate heptahydrate, 5%-8% of zinc Sulphate Heptahydrate, 3%-9% of borax and 0.5%-0.7% of ammonium molybdate, and the sum of the weight percentage of the raw materials is 100%. A product conforms to the humic-acid-containing water-soluble fertilizer standard (NY1106-2010). The fertilizer produced by the invention can meet requirements for growth of Tieguanyin tea, the product is diluted by 500-600 times and sprayed on leaves, then the yield of Tieguanyin tea can be increased by 10%-20%, content of amino acid, tea polyphenol, caffeine, aqueous extracts and the like in tea can be increased, and the tea quality can be improved.

Description

technical field [0001] The invention belongs to the field of fertilizer for tea. Background technique [0002] Fertilizer is an indispensable nutrient in the growth process of Tieguanyin tea tree. Scientific fertilization can improve the growth environment of Tieguanyin tea tree and improve the yield and quality of Tieguanyin tea. In addition to the nutrients such as nitrogen, phosphorus, and potassium needed for the growth of tea trees, some small organic molecules, such as humic acid and plant hormones, can also promote the growth of tea trees. The role of humic acid in the growth of tea trees is: (1) to promote the growth of the root system of Tieguanyin tea tree; (2) to promote the absorption and utilization of nitrogen, phosphorus, potassium and trace elements by tea trees; (3) to promote the formation of soil aggregates, It can also complex with heavy metal ions in the soil to passivate heavy metal ions and prevent heavy metal ions from entering the tea tree system in...
