Tea tree is an evergreen crop that has been growing for many years and absorbs a certain amount of nutrients all year round. Therefore, the fertilization of tea trees must combine organic fertilizer with chemical fertilizer, and organic fertilizer with phosphorus and potassium.

Fertilizer is used as base fertilizer and nitrogen fertilizer is used as topdressing.

Phosphorus and potassium fertilizer as base fertilizer: fertilizers applied to tea gardens in late autumn and early winter are collectively called "base fertilizers".

At this time, the aboveground part of the tea tree entered the dormant period, and the root system was still active, but it absorbed more nutrients.

Slow down. If decomposed organic fertilizer is applied, it is best to use decomposed cake fertilizer or phosphorus and potassium fertilizer. The base fertilizer should be applied sooner rather than later, and it is best to apply it immediately after the tea season.

Nitrogen fertilizer as topdressing: nitrogen has the closest relationship with tea yield, and reasonable application has a significant effect on increasing yield.

Germination-accelerating fertilizer: tea trees grow vigorously in spring, with a large amount of growth, high tea yield and good quality. In order to promote the early, multiple, uniform and strong growth of new shoots, the germination accelerating fertilizer should be applied in time.

High annual output and quality are extremely important.
