Text/Picture of Zhou Chao, Deng Jiangang Special Correspondent "Now is the time to thin the citrus fruit trees. When thinning the fruit, you should not bear this reluctance. That reluctance will not only consume the nutrition of the fruit tree, but also cause the fruit to grow poorly. It fails to achieve the goal of making it a high-quality fruit after thinning the fruit. The thinning of the fruit must be long enough to eliminate the shortness of the disease.†On July 26, in the orchard of Xiao Liang, a citrus grower in Longgu Village, Dagu Town, Naxi District, Luzhou City, the village’s agricultural technician Yang Heqiang picked off a citrus. Said to Xiao Liang. Stay long and short The thinning and keeping of citrus fruits does not mean that you need to choose the length of the branches to retain the fruits, but to preferentially choose the young fruits with longer stalks of the remaining fruits. The purpose is to ensure that the later fruits are easy to operate during bagging operations. Will knock off and hurt the fruit. In the citrus thinning operation, first observe the fruit hanging on the branches before thinning the fruit, and preferentially retain the young fruit with a slightly longer stalk. Generally, the fruit stalk that results from the top of the shoot will be relatively long, and this The bagging of similar fruits in the later stage is also easier to operate. Citrus thinning and shortening means that when choosing to retain fruits, try to choose to leave young fruits with long stalks and thin out fruits with shorter stalks to ensure that no fruit drop occurs during the bagging operation in the later period, and Citrus fruits with short stalks delay bagging time and increase labor costs. Weakness When thinning the fruit, after ensuring the amount of fruit remaining on each branch, we must first thin out the young fruit at the short stalk (branch) and some upturned fruits. For young fruits with bad epiphytic parts, such as lateral pedicle fruits, shrugged fruits, etc., also be removed. When thinning the fruit, the diseased fruit should be unconditionally and resolutely removed. This kind of fruit stays on the tree and will affect the normal expansion and growth of other fruit. For some weak fruits on citrus fruit-bearing branches, consider the overall fruit-bearing amount of the fruit tree and the amount of remaining fruit on the surrounding branches. One is that when the overall fruit-bearing of the fruit tree is suitable, such weak fruit should be removed in time; the second is that although the overall fruit-bearing amount of the fruit tree is not enough, the amount of fruit hanging around the weak fruit is sufficient. except. Fruit thinning time Generally, the first fruit thinning is required in June and July. The object of the first fruit thinning is to remove some fruits that are too large or small to ensure that the fruits can grow evenly and reduce the burden on the fruit tree; the time for the second fruit thinning is before the autumn harvest. At this time, it is necessary to remove too large or small fruits. , And fruit with diseased shape and bad shape, to ensure that the fruit absorbs nutrients evenly. The first fruit thinning is mainly to remove the diseased and insect fruit, deformed fruit, the thick-skinned fruit on the periphery of the crown, the upright fruit and some densely growing small fruit. The abnormal fruit with multiple fruits at the same growth point is all early Omit. If the amount of fruit hanging is too large, a part of the fruiting branches can be shortened, and the fruit can be removed to become nutritious branches. In the second thinning, the small fruits, extra-large fruits, coarse-skinned fruits, deformed fruits, rhizoma fruits, sunburned fruits and excess fruits are removed according to the leaf-fruit ratio of the retention standard to make the remaining tree fruits uniform in size. After more than two fruit thinning, the fruit has gradually grown, and the fruit can basically be determined. This time the fruit thinning is generally done in conjunction with the fruit bagging. This is because the amount of fruit thinning this time is not large. It is just a fine identification and thinning. It feels a bit too much for the fruit hanging on some branches. Clear, complete the final set fruit bagging. Precautions Full consideration should be given to the tree vigor when retaining fruit. Old and weak trees should retain less fruit, and young and strong trees should be retained more appropriately. For the trees in the high-yield period, more fruits can be left on the upper part of the canopy, so that the fruits can press the tree and control the upward growth momentum. But for the first fruit trees, some upper fruit should be kept less to ensure the growth of the tree. After thinning the fruit, pay attention to nutrient supplementation, such as spraying with biological stimulants, to promote fruit expansion and fruit quality.
