Peach size and quality are good and bad, and thinning and fruit thinning are the key. The majority of peach varieties have a high percentage of fruit set, and the fruit quantity in the fruit period often exceeds the load of the tree. Reasonable thinning and fruit thinning can increase fruit size, improve fruit uniformity and fruit quality. According to researcher Song Hongfeng, a researcher at the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences, the thinning and fruit thinning of peach trees is an important technical measure in production management, and sparseness is not as good as sparseness. The sparse flowering is generally carried out during the bud stage and flowering period, and the flowers and double flowers at the base of the dense and fruiting branches are mainly eliminated. The vigorously developed flowers and single flowers in the upper and middle branches of the fruit tree were kept. The flowers on the preparation branches were completely removed. The distance between the flowers was even and the layout was reasonable. The amount of thinning is generally three-thirds of the total flower. Thinning fruit is divided into 2 times, the first time in about 20 days after flowering (if thinning, you can not perform the first fruit thinning). Eliminate the tops and bases of fruiting branches Fruits, small fruits, malformed fruit, double fruits, fruit in the middle of branches, sparsely 6 to 8 fruit in long fruiting branches, 4 to 6 fruit in middle fruiting branches, 2 to 4 in short fruiting branches fruit. The second fruit thinning is also called fruiting. The fruit should be determined according to variety, tree vigor, age, etc. When the tree vigor is weak, the amount of fruit remaining can be appropriately reduced, and the small and medium-sized fruit tree can increase the amount of fruit remaining. Generally, 3 to 4 fruit trees are left in the long fruit branch, 2 to 3 fruit in the middle fruit branch, and 1 to 2 fruit in the short fruit branch. It is advisable to sparse early maturing varieties, large fruit varieties and varieties with high fruit setting rates. For those with serious physiological fruit drop and low fruit setting rate, they should sparse lately and keep more fruits. Mastering the completion of fruiting in mid-May. For the whole tree, the upper part of the canopy and the periphery have more fruit, the inner part and the lower part have less fruit; the strong branches stay more, and the weak branches stay less. When the fruit is thinned, it should be top and bottom, first inside and outside, and avoid touching the fruit. The fruit-type cultivars are 20-30 cm apart; the medium and small-fruit cultivars are 15-20 cm in pitch (slight twig-type pruning should appropriately reduce the fruit spacing). Peach trees of different ages were thinned and thinned according to the target yield. The saplings planted in the open field for 3 years generally have to remove all the flowers and fruit in the first and second year to promote the vegetative growth of the tree. In the third year, a small amount of fruit is retained, and the number of fruit left per tree in the high-yielding tree of more than 4 years does not exceed 250 pieces. The fruit-shearing time of peach trees in different parts of Jiangsu varies depending on the temperature. The fruit thinning can be started in the Nanjing area around May 10, and the fruit-shearing time in the coastal areas and Huaibei area can be postponed as appropriate.
