Abstract: Replanting, heavy pruning and collar pruning are the main reforming methods for low yield and senescent tea plants. Tea as a perennial crop, it is necessary to evaluate these methods in the long run. A study was conducted in Hangzhou tea experimental station for at least 20 years. The effect of these methods on the yield, production value and economic benefit were compared. The results showed that heavy pruning was a better rehabilitation method for shorter period and more quickly effect, but in the long run, replanting has better economic benefit. It is better to combine replanting and heavy pruning after spring tea to get both short-term and long-term economic benefit in practice.

Key words: heavy pruning, replanting, collar pruning, middle and long term effect
