Tea tree pruning technology

Tea tree pruning is a measure that artificially suppresses the growth advantage of the top branch, which stimulates the emergence of new shoots with lower buds, enhances tree vigor, and cultivates high-yielding and high-quality canopies. 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.

First, the shape of young tea tree pruning

After the tea planting, when the seedling height reaches 30 cm or more and the main branch is thicker than 3 mm, it can be trimmed for the first time, leaving a height of about 15 cm after cutting. 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 fertility management. Each trimming height can be increased by about 15 cm on the last cut. After 3 times of shaping the tea tree, the height is between 40 and 50 cm. At this time, the skeleton has been formed. Afterwards, it is supplemented with the top-lighting and light trimming to further cultivate the crown and picking surface. For the tool for shaping and trimming, the first fixed cut should be pruned with pruning shears and the first axillary bud should be cut 3 to 5 mm away from the incision, and the lateral buds should be kept as far as possible so as to facilitate the growth into a strong backbone. When the conditions permit, the second set of pruning should still use pruning shears, which is helpful to improve the quality of pruning.

Second, the light and deep pruning of mature tea trees

1. The purpose of light pruning The purpose of pruning is to promote the growth 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, to cut the 3 to 5 cm on the plane of the leaves for the degree, you can also cut the last year's autumn shoots, leaving the summer shoots. In the form of light pruning of medium- and small-leaf tea trees, it is advisable to cut the incision into a curved shape so that the width of the harvesting width can be increased, which is advantageous for increasing the yield. For green and young tea trees, light pruning can be performed once a year or every other year. Every time the original cuts are increased by 2 to 3 cm.

2. Deep pruning tea trees After many years of harvesting and light pruning, dense and delicate branches will form on the picking surface. This is often called the "chicken claw branch", and the tea yield and quality 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 germination ability can be improved, and the longevity and longevity can be prolonged. Deep pruning should cut the crown shoots, too shallow to achieve the purpose of updating the picking surface. Deep-trimmed tea trees are still to be trimmed every year or every other year, and new leaves are added as appropriate to re-cultivate the picking surface.
