Tea tree pruning method

Tea tree pruning is based on the comprehensive management of soil, fertilizer, and water in the tea plantation. Based on the natural conditions, age, and species growth habits of the tea plantation, the distribution and operation of the nutritive substances in the tea tree tree are appropriately controlled and adjusted so that nutrients are used rationally. And the allocation of a measure. However, it must be closely coordinated with the management of fertilizers and water, combined with the collection of leaves, and pay attention to the control of pests and diseases, in order to make the tea tree restored quickly and grow well.

Shaping

The first type of young tea tree is pruned, and its height and branch thickness are closely related to the strength of branches and the number of branches. In accordance with the branching habits of shrub-type tea trees, when the height of the two-foot-old tea seedlings is more than 30 cm, the main stem is 3-4 mm thick, and there are 1-2 branches, the first shaping pruning can be performed, and the height of pruning can be separated from the ground. 15-20 cm is appropriate. Poorly grown tea trees, although of two-foot age, do not reach the standard and should be postponed for styling. Some tea trees with deep soil layer and good management level have reached the standard at the age of one foot, and can also be trimmed one year ahead of schedule. The first type of pruning must be careful, only the main branch is cut, and the side branch is not cut. The clipping position should be closer to the lower position leaf, and the pile should not be left too long. The incision should be inclined to the inside to keep the lateral bud position as far as possible. After the first type of pruning, it is necessary to strengthen the management so that the tea tree will exude a vigorous new branch as soon as possible. The second shaping height can be increased by 15-20 cm on the first cut. The third trimming height was increased by about 10 cm on the second cut. In this way, after three consecutive hair cuttings, the height of the tea tree skeleton can reach 50 cm. Together with the main stem, it forms 4 to 5 layers of branches. On this basis, the lighter trimming is combined with the topping to further cultivate the crown of the tea tree. Picking noodles.

Small trees have strong apical dominance, tea tree shoots grow more prosperously, and internodes are longer. It is not appropriate to adopt the shrub-type tea tree's styling and pruning methods. Instead, use segmented pruning methods to perform styling pruning. When the tea grows in accordance with one of the following three criteria, it can be shaped and trimmed: First, the main stem is 4 to 5 mm thick, and the height is more than 20 cm. The second is that there are 7 to 8 leaves. Third, the branches are lignified or semi-lignified. Pruning method: The first shaping pruning is still about 30 cm high in the tea tree, and when the main stem is more than 4 mm thick, it is trimmed from the ground 12 to 18 cm. After the first pruning, the tea tree grows to 20 cm or more and has 2 Trimming begins at the time of ~3 branches, trimming every 20 to 40 days, trimming 5 to 7 times a year (same branches can be trimmed 2 to 3 times), and only trimming 1/3 of the number of branches that meet the standard. ~ 1/2. Pruning branches to keep the length of the pile from the branching fork extension of 8 to 12 cm, the central branch should be strong pruning, leaving 8 to 10 cm, the side branches should be lightly trimmed, leaving 10 to 12 cm, pressure main side, shear strong and weak, after For two years of pruning, trim the tea tree crown once when the height of the tea tree reaches 60 cm. Afterwards, only the strongest branches of the tea tree were pruned, combined with leaf picking, and the invalid branches were cleaned, so that the production branches formed a balanced, denser surface.

The cultivation of the stem and skeletal layers of the young tea tree canopy mainly depends on three types of shaping. In picking techniques, "leaving leaves in batches" should be implemented, and more efforts should be made to keep more harvests, and to focus on raising, supplementing picking, and implementing light topping. In production practice, two tendencies should be taken care of. First, only the immediate interests are taken into account, and the basis for the growth of tea plants and the realization of high yields and stable production are not considered. They are eager to achieve success, improperly early mining, and strong mining, resulting in premature decline of tree vigor, and the output will never go up. Tea tree is difficult to seal. The second is that the mining is not adopted, the implementation of the closure of the park raised Peng, the result can not reach the purpose.

Light trim

Light pruning is the practice of pruning on the basis of stereotyped pruning to continue the cultivation of tea tree canopies and picking surfaces. Shearing usually increases 4 to 8 centimeters in the previous year. Spring tea leaf picking, leaving spring shoots, cut summer, autumn shoots. Spring tea does not leave leaves but the summer tea leaf picking, cut the summer and autumn shoots stay more than the true leaves tip. If spring and summer tea leaves are picked, the net height of the canopy is subject to pruning, and it is not appropriate to keep the pile too high. Cut lightly with a horizontal shear and cut it smoothly. Light pruning should be done during the late autumn or early spring tea tree dormancy period. After pruning, tea plantation management should be strengthened. Pruning every other year or more every two years or more and picking leaves from spring tea leaves spring tea mining earlier, increasing spring tea production and improving economic efficiency.

Deep pruning

Deep pruning is mainly the removal of tea tree claws, redundant branches, dead branches, to promote the tea tree germination of new branches, the formation of new production branches, improve the ability of budding. Generally, the deep pruning cycle is often more than 5 years. After deep pruning, the deep pruning should be performed again when the crown production of the tea tree crown reappears. Deep pruning cuts deeper and generally lowers the crown by 15 to 25 centimeters. Deep pruning is often done after spring tea picking, so that one spring tea can be obtained. After the deep pruning, the harvesting must be stopped in order to cultivate the tree vigor. It can be harvested only after the reconstituted production branches of the tea tree canopy in the following year. If deep pruning is done at the end of autumn, the spring tea of ​​the following year should be kept for one season and picking should begin again in summer.

Heavy trim

The heavy pruning is suitable for tea gardens in which the main branches in the aging tea garden are still strong, 1 to 2 branches are also strong, and the upper branches are messy and tea gardens with premature failure. Heavy pruning is generally about 40 centimeters away from the ground. After cutting, only the main branches and 1 to 2 branches are left. The particularly aged branches of the tea bush can be cut off from the roots, and the thin branches in the natural regeneration branches can be cut off at the same time, and robust and renewed branches can be kept. Generally, the pruning is performed during the dormancy period after picking the spring tea, and cutting is performed with a sharp knife or a rake, and the incision must be smooth and slightly beveled, and the fertilizer must be weighed heavily after pruning.

Taiwan

The Taiwanese wolfberry is mainly aimed at the tea tree with serious tree aging. It cuts off all the canopies from the roots (within 5 cm above the ground), so that the adventitious buds of the roots sprout to form a new canopy. The pile should not be too high, otherwise it will not be able to germinate and the new branch will be slender. Taiwan’s razor blades are cut off with sharp knives, saw off thick branches with a saw, and avoid damage to the pips to prevent decay and affect development. Some senescent tea trees have sprouted many natural regenerating branches from the rhizomes, such as these branches are thick, and other branches of the same strain are already very old and can be used for convulsive methods to cut the old and stay strong, using the remaining renewed shoots to shape pruning, composition New canopy. Taiwanese wolfberry should be carried out in the spring so that the new shoots can be lignified by one year of growth, making it easy to prune in the following year. Taiwan must be combined with improved soils and organic fertilizers in order to achieve the desired results.
