The Anxi Tie Guan Yin tea in Fujian is now in pollution-free cultivation, while the most critical technical measure is to

master the garden soil management and fertilization technology.

The technology of tea garden soil management

Technical measures of soil tillage and effective roles

The pollution-free tea garden emphasis much more on moderate and deep cultivating.Moderate cultivation usually being

conducted before the spring tea, once a year with the depth from 10-15cm, which is good for the germination and new leaves

growing of the spring tea.The deep cultivation usually conducted once or twice a year has a strong effect on aging and

promoting soil, thickening live soil, and decreasing pests.However, the deep cultivation may easily break the tree roots, so

it is a high-tech measure and harder to master. It requires flexible cultivating times.Deep cultivations in all types of tea

gardens are being conducted after the autumn dragon well tea ( winter), together with the spraying lime sulfur and comprehensively

cleaning work.

The technical measure of soil covering

After the shallow plowing, picking the safe, clean and pollution-free straw and weeds to cover the soil 10cm far from the

root before the drought. The cover is required to be uniform and thickness of 8-10cm and the soil should not be seen.In the

tea gardens on the sloping fields, people put the cover in horizontal direction, which may protect from the straight rush of

rain, as well prevent the cover accumulating when rain water flows.Deep cultivation in autumn and winter may not only turn

the covers over into the bottom to be fertilizers but also prevent weeds and soil erosion, so that may adjust the earth

temperature to promote growing.
