The growth of the young tea tree at the top is obvious. At this time, it is very important to cultivate the tea tree canopy structure and the tea plantation phase that are both high in yield and stable in quality. For this reason, the author used more than five years to practice and explore the practice of styling pruning in 1600 mu of tea gardens planted in 1989, 1990, and 1991, respectively, and summarized a set of effective “dwarfed†trees. The "pruning" technique of the law is now described as follows: 1. Prior to the establishment of tea plantation garden phase, the tea tree height and aspect ratio to be controlled should be designed before the young tea tree is shaped and pruned. After this method is implemented, it is required that the height of the tea tree at the time of production is 70 to 75 cm, and the maximum height is 75 cm, and the aspect ratio is controlled at 1.0:3.5 or 1.0:4.0. 2. Formulating the shearing procedure and criteria according to the determined tea plantation phase objectives (1) The first stereotyped pruning, the main branch height is controlled at 8 to 12 cm, and the maximum height is not to exceed 14 cm; the second stereotyped pruning is performed at the first time. Based on the increase of 10 ~ 12cm. After that, on the 3rd, 4th, and 5th, and so on, cutting at the corresponding height, until the height of 60 ~ 70cm after the 6th shaping pruning, the young tea plantation enters the initial stage of production. (2) The tea tree grows when it meets the standard height required for shaping and pruning, and when the branches reach the semi-lignified or lignified degree, they are sheared. (3) Cut the lower part of all the left lateral leaves, cut the mouth parallel to the leaves, in order to facilitate the crown surface expansion and prevent the cut of the mouth water or bacterial infection affect the growth of tea. (4) When cutting, all branches of pests and insects must be cut off, and the thin and thin branches should be removed according to the angle of the branches. Especially when 1 to 3 times of pruning, the thinning is more important. (5) In each cutting, only the branches that have reached the pruning standard can be cut, and if they do not meet the standards, they will not be cut. (6) 1 to 4 times shaping tools can only use pruning shears, it is strictly forbidden to use large hedgehog. In addition, the application of basal fertilizer, topdressing, and the comprehensive prevention and control of pests and diseases is a guarantee for the implementation of the "staged dwarfing method" for cultivating cultivated fields. It must be strictly followed. Especially after the tea tree has been cut, if the nutrient supply is insufficient, the wound will not heal quickly and the new shoot will not grow in time. If the young shoots of tea shoots just extracted are harmed by pests and diseases, the tea tree cannot grow healthily. The styling pruning can not be carried out in time, which will eventually affect the effect of the "segment dwarfing method" shaping pruning technique. Practice has proved that using the "fragmented dwarf method" stereotyped pruning tea garden, tea tree stem branches thick and well-distributed, the crown structure is ideal, short and neat, fast formation of the cover, coverage is conducive to the tea tree on soil nutrients and moisture The effective use is conducive to the implementation of crown-management work such as mechanical picking, pruning, pest control, etc., and ultimately can achieve high-yield, stable production, and high-quality tea planting purposes. The "staged dwarf method" shaping pruning technique has practical application value in the management of young tea gardens and is worthy of promotion.
