Detailed Explanation of the Key Technical Points for High-Yield Lemon Cultivation and Management

Lemons are sour and tasty and can be used in condiments and health products. They are a fruit deeply loved by the public, and many people have invested in growing lemons. Today, the editor will introduce to you the high-yield management techniques for lemons.

1. Fertilizer and water management

The characteristics of fertilizing lemon trees are that spring fertilizer should be applied early, fruit-setting fertilizer should be applied as appropriate, more fruit-swelling fertilizer and post-harvest fertilizer should be applied, and fertilizer should be applied at least three times a year. The specific amount of fertilizer used is determined by the number of fruits and the fertility of the soil. Fertilizing lemon trees is mainly based on farmyard manure, supplemented by chemical fertilizer. When new shoots grow at the beginning of spring each year, spring flower fertilizer is applied. Spring flower fertilizer is mainly quick-acting fertilizer and organic fertilizer. Trees with weaker growth and more flowers should be given more, while trees with strong growth and fewer flowers can be given less or not at all. The water requirements of lemon trees are also relatively important. If drought occurs, water should be replenished immediately to ensure that fruiting trees have sufficient water supply during the spring shoot emergence period and young fruit period for development and fruiting.

2. Reasonable pruning

The shaping and pruning of lemon trees can be carried out in all four seasons, but it is mainly done in winter and spring, with the growing season as a supplement. In the early stage of fruiting trees, light thinning and long branching should be the main approach, with the goal of cultivating excellent fruiting mother branches and maintaining a gradual increase in flower quantity each year. However, as the tree age increases year by year, the pruning amount of the tree body should also begin to increase appropriately. In pruning, summer pruning is still the main approach. One purpose is to prune overly long branches and enhance the airiness and light penetration of the tree body, and the other is to cultivate the tree shape by thinning and pruning branches that may disturb the tree shape, retaining relatively weak spring and autumn vegetative branches as mother branches. The purpose is to ensure sufficient flower quantity and fruit set for the coming year, so that the tree's nutrients are promptly directed toward reproductive growth.
