Description

The special use of a kind of Iron Guanyin tealeaves contains the humic acid water-soluble solid fertilizer

Technical field

The invention belongs to the tealeaves fertilizer field.

Background technology

Fertilizer is nutrition indispensable in the Tie Guanyin tea plant process of growth, applies fertilizers scientifically to improve the growing environment of Tie Guanyin tea plant, improves extra-strong tea leaf-making quantity and quality.Growth of tea plant is except nutritive elements such as needs nitrogen, phosphorus, potassium, and some organic molecules also have the promotion crop as humic acids, plant hormone to the growth of tea tree.Humic acids acts in growth of tea plant: (1) promotes the growth of Tie Guanyin tea plant root system; (2) promote tea tree to nitrogen, phosphorus, potassium and trace elements absorbed utilization; (3) humic acids can promote the formation of soil granular, can also with soil in the heavy metal ion complexing, play heavy metal-passivated ion, prevent that heavy metal ion from entering the effect of tea tree system in a large number.(4) improve the extra-strong tea leaf-making quantity, improve quality.Sell in the market to contain the humic acid water-soluble fertilizer variety many, do not relate to as yet but the special use of Iron Guanyin tealeaves contains humic acid water-soluble fertilizer.
