Naturally grown tea trees are sparsely crowned and dominated by growth spindles. Branches are not dense, branches are uneven, and it is difficult to form a wide and densely harvested surface. Inconvenient harvesting results in low yields. If reasonable pruning methods can be used to regulate light, remove the leaves and branches of pests and break the growth balance between the ground and the underground, forcing the tea tree to change the original natural growth state, rejuvenate growth potential, form a good canopy, and then achieve high yield and quality of tea. Trimming can be divided into trimming, light trimming, deep trimming, heavy trimming, and pedicure.
1, shaping pruning
Stereotype pruning is to lay the foundation and cultivate the pruning of the crown. When the biennial main stem of tea trees is 0.4-0.5 cm in stem diameter and one or two branches are used, cut the main branch 12-15 cm away from the ground and keep 1-2 strong branches when cutting. In the second year, the pruning was performed for the second time. The cut was cut with hedge shears. The height of the cut was 25-30 cm, which was based on the first type of trimming. The lO was 15 cm. The third type of pruning should be performed about one year after the second pruning, and the pruning height should be increased by about 10 cm. Since the purpose of this pruning is mainly to establish the upper backbone, and to spread the branches on this basis, While shearing with hedge shears, cut fine and weak branches and pests and branches with a pruning shear to reduce nutrient consumption.
2, light trim and deep trim
Light trimming and deep trimming are trimming the crown and maintaining the growth of the tea tree. After the tea tree is sculpted and pruned, in order to adjust the growth potential of the tree crown during the formal picking period, the production branches of the picking surface should be arranged, the thin and weak branches should be reduced, the growth branches should be promoted with multiple lateral buds, and the height and amplitude of the canopy should be controlled so that the germination can be matched and the picking can be facilitated. Every year or every other year, the irregular branchlets on the canopy are cut 1-3 cm by hedge shears, which is based on the principle of not damaging the fertility of the lateral buds. The period of pruning should be after the harvest of spring tea or in the autumn growth rest period. For example, in the early spring, the growth potential of the bud should be taken care of, so as not to harm the bud and cut it from the night frost. General tea area should be cut early, shallow shear, pruning degree to grasp the spring shoots left a red stem, autumn yellow shoots sweep light is appropriate.
After several years of tree-picking, the twig growth on the surface will be too dense, too fine and multi-nodular. When the ability to germinate is weakened and poor, even when there is a tendency to reduce production, deep shears are used to cut the crown surface. In centimeters, the principle of cutting off the nodular shoots promotes the renewal of crown production branches.
3, heavy shear and Taiwan
Heavy shears and pedicures are pruning of crown reconstruction. On the crown canopy senescence and multiple nodules, tea buds are difficult to germinate or form a pair of clips. Tea production is low and the quality is poor. Some senile tea trees with leggy branches appear at the root neck, and heavy shears or Taiwanese must be used to update the canopy.
Heavy shear is generally used for the growth of the backbone. The age of the tree is not very old. It is only the aging tea tree or the premature tea tree that is formed due to poor management or picking is unreasonable. Generally cut off the upper part of the tea tree 30-40 cm above the ground. Branches, when the shoots grow to about 10 centimeters in length, appropriate top picking, with light shears, adjusting the canopy, and strengthening water and fertilizer management.
Taiwan’s ancestors cut off all the branches of the canopy and used the adventitious buds of the tea tree roots to regenerate the crown and the upper branches. Tea gardens are old, low yield, main trunk is dry, branches are sparse, pests and diseases are seriously damaged, and it is difficult to restore the tree vigor with common cultivation measures. Use rakes or brush cutters at 5-10 cm from the ground. Cut off all branches from the ground. The new branches after the taiwanese were also subjected to stereotyped pruning to rejuvenate the strong canopy.
In addition, it can also be based on market demand for new instructions for the "three-year two-headed rake" special pruning, that is, only the spring harvest season, and then through the pruning or Taiwan special methods to promote early spring tea. Adult tea plantation is put into operation every year to finish pruning or regrowth at the end of the spring tea season, and to promote the early occurrence of hair buds in late spring. After pruning with this method, the next year's tea tree extraction period is 7-8 days earlier than regular tea plantation. “The material is rare,†and its economic benefit is very significant. Although the use of Taiwan's mullion shears has affected tea production, it has mainly affected the production of medium- and low-grade teas, and has not affected the output value of tea.
The use of special pruning methods should grasp the following technical points: First, the age of Taiwanese tea gardens is usually implemented immediately after the end of spring tea, young tea gardens can also be relatively early; Second, the height of Taiwan gongs 5-20 cm, can be increased year by year; Third, 100-500 kilograms of compound fertilizer per acre for growing-up tea plantations, and 1,000-1,500 kilograms of manure; the fourth is to strengthen field management and timely control of pests and diseases.
