The loquat fruit should be pruned as soon as possible after harvest, and pruning after harvest is an important pruning of loquat, which should be done sooner rather than later. In order to produce a large number of good new shoots, it is necessary to fertilize again after harvest. Summer branch is the most important branch of loquat in a year and the main fruiting branch. Pruning usually ends within 30 days after fruit picking, and the earlier the better. Pruning will affect the germination and growth of summer shoots, which is not conducive to cultivating strong fruiting branches.

The loquat in the hospital is combined with post-harvest pruning, focusing on shaping. It is necessary to change the shape of natural growth in the past and gradually shape it into 2 ~ 4 layers. Specific operation: the height of 1 floor is 50 ~ 60cm above the ground, and the spacing between the above floors is 80 ~ 100cm: three branches are left on each floor and evenly arranged at 120, and the branches between the upper and lower floors should be staggered and not overlapped, so as to ensure the permeability of each floor and increase the bearing layer.

Extended data:

blossom and fruit thinning

Loquat flower buds are easy to form, with many flowers and high fruit setting rate. In order to save nutrients, flowers should be thinned as soon as possible. It is better to sparse flowers late than early, not to sparse buds, flowers and young fruits. It is best to use the technology of thinning flowers and fruits correctly, control the number of fruits per ear, make the burden of trees reasonable and ensure the good development of fruits.

First, the principle of flower thinning: the flower branches and nutrient branches of a loquat tree should maintain a certain proportion. The ratio of flowering branches to vegetative branches is 1.5: 1, which is beneficial to stabilize flowers and fruits. In warm areas without freezing injury in winter, when the ear is identified by naked eyes in June 10~ 1 1, the ear should be thinned as soon as possible before it is separated on the ear axis (peduncle).

Second, the principle of flower bud thinning: loquat usually has 50 ~ 100 flower buds per ear, and as many as 200, which makes it bear fruit naturally and can bear dozens of fruits per ear.

Third, loquat trees thin young fruits, and the number of fruits selected for loquat thinning should be determined according to the variety of fruit trees, the strength of trees and the length of fruiting branches. According to local experience, 3-4 fruits are reserved for large fruit varieties, 4-6 fruits for medium fruit varieties, 7- 10 for small fruit varieties, and 4-6 fruits for fruit branches with large leaves less than 10. The excluded young fruits are mainly pests, deformed fruits, frozen fruits and small fruits, which are too dense.
