Work to prepare a branch after the second tea

I can seize quantity of outbreak of the main pest by being shallow, and performing work (I lower it by 5-10cm from the aspect that picked up the second tea) to cut after the second tea.
After the tea again first the growth of the autumn bud is shallow, and is equal to the tea plantation which worked to mow, and can find the first tea yield in the next year at the same level.
