Golden Pear is a high-quality late-ripening new pear variety developed from a cross between a new high and a 20th century in Korea. This variety has good characteristics such as early fruit, high yield, good quality, and high economic efficiency. However, to fully express its good traits, it is also necessary to first understand its growth characteristics, and to formulate a matching plastic trimming technology.
Young trees grow slowly and their canopies are short. Compared with other Japanese pear varieties, young pears grow slowly. The heavier the pruning, the smaller the amount of growth, will affect the growth of the tree, affect the early yield of young trees, and even delay the arrival of the full fruit period.
The top edge is strong and polarization is obvious. During the sapling period, the golden pears have strong erectness, and they are prone to “strong and weakâ€, “strong outside and weak†and “strong on the back and weak on the backâ€.
The bud rate is high and the branching power is low. In addition to the blind section of the base, most of the buds can germinate. After germination, more short and short fruit branches were formed, and less middle branches or middle and long fruit branches. After the golden pear branches were short-cut, two long branches occurred, and a few had three long branches. Gold pears have low branching force, and it is not easy to issue new shoots after the results. When pruning, attention should be paid to updating, and the result of rotation should be well done. The overlying branches should be cut from the base to keep the new branches.
Saplings stand upright and the crown does not open. Young pears stand upright and the crown does not open. The heavier the trim, the more upright the angle. When saplings are trimmed three years ago, it is advisable to use multiple light and short cuts or dump extensions to promote crown opening. The golden pear branches are soft and the result is easy to droop. Therefore, the angle of the pull branches should not be too large. Generally, the angle can be pulled up to 45 degrees, and the maximum is not more than 60 degrees.
Strong and weak, the main strong side weak. During the saplings of Golden Pear, the phenomenon of “strong in the main trunk and weak in the main branch†often appears. Compared with the main branch, the lateral branches are small and weak. Therefore, when saplings are pruned, they must follow the principle of “strengthen the weak and strengthen the weak, and focus on helping the weakâ€, and pay attention to solving the problems of “strengthening the main weak†and “the strong weak sideâ€.
Easy to flower, early results, high yield. In the second year after the planting of the golden pear, there will be more alfalfa buds on the middle and long branches, and there will also be a small number of short- and middle-fruit sticks. Sapling buds have a high rate of fruit set and fruit shape, which can be properly used to start the result of years in advance and increase early yield. Golden pears generally begin their results in the second year of life. The two-year-old students enter the first fruit period, and five to six-year-old students enter the fruit period. The yield per hectare in the full fruit period should be stable and maintained at a level of 3.7 to 45,000 kilograms. Golden pears should be properly cut off some of the flowering branches during the high-yield period, control the back branches, and retreat and rejuvenate in time after slowly putting them into flowers.
The new branch has a good result and the old branch has a poor result. The young fruit of the golden pear (fruit branch from 1 to 2 years old) has a high rate of fruit set, a large fruit, and good quality. Fruits of more than three years of age result in small fruit and poor quality. Therefore, when pruning, attention should be paid to the method of frequently updating result branches to rejuvenate the results.
The short and mid-branches have weak transforming power and strong differentiation. Compared with white pear varieties, the short and middle branches of golden pears had weaker transforming power, but the ability to differentiate from long branches to medium and short branches was strong. The short and middle branches of golden pears are very easy to flower. After the results, the branches were shorter. After many years of evolution, short fruit bunches have formed.
