Tea tree pruning and picking technology
(A) tea tree pruning tea tree pruning is artificially inhibiting the growth of the top branch of the main measures, can stimulate the germination of the new parts of the lower buds new technology, enhance tree vigor, and cultivate high-yield and high-quality canopy. The tea tree pruning methods mainly include the shaping pruning of young tea trees, the light pruning and deep pruning of mature tea trees, the heavy pruning of senescent tea trees, and the Taiwan puppets. Tea tree pruning period, theoretically best before and after the start of the thrill of spring. However, in order to consider the current economic benefits of spring tea, in addition to the shape of the young tea tree pruning, other pruning should be arranged after the end of the spring tea is better. Shaped pruning of young tea trees 1. After the establishment of young tea trees with fixed pruning tea seedlings, when the seedling height reaches 30 cm or more and the main branch is thicker than 3 mm, the first shaping pruning can be carried out, and the shear height remains 15 Centimeters or so. Poorly growing tea plants, when they do not meet the above criteria, should postpone establishment of the pruning period. After shaping and trimming, attention should be paid to keeping new shoots and strengthening management of fertilization. After one year, shape trimming is performed. The height of each trimming can be increased by 15 cm on the last cut. After three times of shaping the tea tree, the height of about 40-50 cm, when the skeleton has been formed, and later supplemented by topping light and light trimming, to further cultivate the crown and picking surface. For the tools for shaping and trimming, the first cut should be pruned with shears to trim the stalks. Cut the first axillary bud at a distance of 3-5 mm from the incision, and keep the lateral buds as far as possible so as to grow into a strong backbone. If the conditions permit, the second set of pruning should still use pruning shears, which will help improve the quality of pruning. 2. Lightly pruning and deep pruning of mature tea trees Light pruning (1) Light pruning: The purpose of light pruning is to promote the sprouting of tea buds, increase the production density, and enhance the growth of tea plants. It is an indispensable technical measure for creating good picking surfaces. . The degree of light pruning is to cut off the leaves of 3-5 cm on the surface of the awning. It is also possible to cut away the autumn shoots of the previous year and leave summer shoots. In the form of light trimming of medium- and small-leaf tea trees, it is advisable to cut the cut into curved shapes so as to increase the width of the picking width, which is advantageous for increasing the yield. For green and young tea trees, light pruning can be done once a year or every other year. Each time the original cuts are increased by 2-3 cm. (2) Deep pruning: After many years of harvesting and light pruning of tea trees, dense and delicate branches will form on the picking surface. This is often referred to as the “chicken claw branchâ€, and the yield and quality of tea gradually decline. In order to update the tea tree picking surface, deep pruning techniques can be used to cut out the dense and weak "chicken claws" layer, so that the tea tree can be re-extracted, the tea tree germination ability can be improved, and the tea tree can be prolonged. Deep pruning should cut the crown of the 1 to 15 centimeters of the crown, and the shallowness cannot achieve the purpose of renewing the picking surface. After the deep-trimmed tea tree, it is still pruned every year or every other year, so new leaves are added and the picking is resumed. Deep pruning 3. Heavy pruning of senescent tea trees and taiwan For senile tea trees, we can re-cultivate the tree canopy and rejuvenate the tree's vigor through high pruning and taiwan rafting to achieve high yield and quality.
