Planting lemons should be carefully pruned.

Lemons, such as improper pruning, often only blossom, no fruit or little fruit, or even do not blossom. In order to make the lemon blossom and bear fruit year after year, the pruning link must be carefully pruned in order to achieve the goal of abundant fruit.

The main purpose of pruning young and primary fruit trees is to cultivate the crown skeleton in order to expand the crown faster and better. Pruning of young trees is suitable in winter, coring and necessary truncation should be carried out in the growing season, and branches and leaves and auxiliary branches should be retained as much as possible. The main points of pruning are as follows:

1. Long tip plucking heart

Young trees should draw long shoots, and after each season shoots are produced, except for keeping 8-10 coring pieces for long shoots, the rest should be tender shoots and coring. It is appropriate to leave a length of 20-25 cm to enrich the robust crown, early branching and multi-branching, so as to expand the crown as soon as possible.

two。 Cultivation of drawing branches and auxiliary branches

For the vigorous growth of upright branches, it is appropriate to use the method of pulling and bracing. The strong branches are pulled down and the solution angle of the larger branches is 40 °~ 50 °. If the young trees are pulled and braced, the young trees can bear fruit 1 ~ 2 years earlier.

Branchlets that usually grow in the crown should be retained as long as they are not overgrown and over-dense. These twigs are often good fruiting mother branches for young trees.

3. Wipe sprouts and shoots and wipe off long branches in time.

Young trees can be sprouted in summer, that is, one autumn shoot, in order to expand the crown as soon as possible. Only growing branches disturb the shape of the tree and waste nutrients, which should be erased in time.

4. Control summer shoot

Young trees with strong growth have more strong shoots. Because the strong summer shoots are not easy to produce autumn shoots and are not conducive to flower bud differentiation, "promoting Huawang 2" is used from May to June to control summer shoot elongation, concentrate nutrient supply, strengthen fruit and promote flowers.

5. Thinning flowers and buds

The buds and fruits of the weak trees before the planned fruit production of young trees should be removed in time in order to promote tree nutrition production and form a fruiting crown and put into production as soon as possible.

6. The trimming mouth is closed in time.

The wound caused by pruning is often the entrance to the invasion of diseases and insects, so it is necessary to close it with a "callus anticorrosive film" in time to prevent dryness and cracking, diseases and pests, and Rain Water pollution.

Lemon pruning is the implementation of branch tip treatment technology for trees, through pruning to artificially regulate the relationship between tree growth and fruit, give full play to the potential of tree fruit, and achieve the goal of high yield, stable yield and high quality.
