Eliminates the bud to pass damps the bud effect to be best. In Shi Yaohou 20 days, each Shi Yao processes damps the bud effect above 90%. 30 days later, eliminates the bud to pass damps the bud effect is 77.18%, passed processing compared to the vegetable grass to be higher than 31.68%, but the smoke processed only suppresses the effect for - 4.74%. Shi Yao processes the economic character to surpass the manual handling obviously, has the remarkable difference. The chemical composition difference is small. The quality synthetic evaluation, passes the performance by the vegetable grass to be most s
