Cultivation techniques of Anxi tie guan yin tea（1）
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.
1.The technology of tea garden soil management
a. 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 tea( winter), together with the spraying lime sulfur and comprehensively cleaning work.
b. 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.
c. The technical measure of cultivating garden with external earth
The pollution-free Dragon well tea gardens should choose the fertile red earth, yellow earth, the red-yellow earth and other clean earth and take to gardens after the tea season every year.。When fill the earth, different nature of tea gardens require different texture of earth.Tea garden with clay requires red sandy earth; the tea garden with sandy earth requires clay; the tea aging garden requires red and yellow earth.
d. The technical measure of intercropping
The tea tree intercropping technology focuses on deal with problems according to the separate tree and the reasonable grasping. For the young tea plantation, people should select legumes, such as soybeans, green beans, peanuts or creeping of the compounds such as potatoes, sweet potatoes, etc. When intercropping, the density should be reasonable, green manure and the tea tree need to maintain an appropriate distance, taking double row hole species, 2 to 3 per hole. When the crops matured should be harvested as soon as possible, and promptly turned leaf stems buried in soil. For adult tea trees, people should choose the deep-rooted water fight fat umbrella-type fruit that not sharing water and fertilizer with trees, such as oil persimmon, longan, red bayberry, peach, plum, etc. Intercropping should be based on coverage and tea tea growing to decide the planting density and the tree varieties, which may control the shade rate from 20% to 30%.
