Detailed Explanation of the Latest Technical Points for Lemon Orchard Management
Lemons like warmth and tolerate shade, but they are not cold-tolerant and not heat-tolerant. According to experiments, the market demand and market price of lemons are steadily rising, and the economic benefits are becoming more and more considerable. Many people are growing them, and although everyone may have a relatively correct planting method, this is still far from enough. After the lemon trees are planted, the orchard management that follows is the most important step. How can orchard management be done well so that lemons bear fruit better? Let's take a look below!
1. Fertilizer and water management
The characteristics of fertilizing lemon trees are that spring fertilizer should be applied early, fruit-stabilizing fertilizer should be applied according to the situation, more fruit-enlarging fertilizer should be applied, and fruit-harvesting fertilizer should be applied as a top dressing. Fertilizer should be applied at least three times a year. The specific amount of fertilizer used depends on the number of fruits and the fertility of the soil. Fertilizing lemon trees is mainly based on farmyard manure, supplemented by chemical fertilizer. Each year at the Beginning of Spring, when new shoots grow, spring flower fertilizer is applied. Spring flower fertilizer is mainly quick-acting fertilizer, with organic fertilizer as the main component. Trees with weaker growth and more flowers should be given more fertilizer, while trees with strong growth and fewer flowers can be given less or no fertilizer. 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 for development and fruiting during the spring shoot sprouting stage and young fruit stage.
2. Reasonable pruning
The shaping and pruning of lemon trees can be carried out throughout the year, 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 letting should be the main approach, with the goal of cultivating excellent fruiting mother branches, so as to maintain a gradual increase in flower quantity every year. However, as the tree age increases year by year, the amount of pruning of the tree body should also begin to increase appropriately. In terms of pruning, summer pruning is still the main method. One purpose is to prune excessively long branches to enhance the permeability of the tree body, and the other is to cultivate the tree shape by thinning out branches that may disrupt the tree shape. Relatively weak spring and autumn vegetative branches are retained as mother branches, with the purpose of ensuring sufficient flower quantity and fruit-setting quantity for the coming year, so that the tree's nutrients are promptly directed toward reproductive growth.
3. Flower and fruit management
In the summer of the previous year, according to various factors such as the growth condition, age, number of fruits, and rainfall of the lemon tree, autumn shoots should be uniformly released, with the purpose of allowing the lemon tree to form good fruiting mother branches. The branches and leaves of the tree should also be protected to avoid being troubled by pests and diseases. In autumn, after the autumn shoots are fully mature, soil loosening and root cutting can begin, with the purpose of controlling the growth speed of winter shoots of the lemon tree and promoting flower bud differentiation for the coming year. After the lemon tree finishes flowering, fruit protection measures should be taken immediately. If rainy weather occurs, the tree body should be shaken promptly to shake the water out of the flowers and avoid soaking the flowers until they rot.
4. Fruit bagging
Although there was no such thing as bagging when growing fruit in the past, after people discovered the benefits of bagging, bagging technology began to become popular. Now no matter what fruit is grown, even some melon-type vegetables, bagging technology can be used. When bagging lemons, plants with strong growth and good management should be selected, and lemon fruits with no differences in appearance, no pests or diseases, and good growth should be selected for bagging. The time is generally chosen around July each year. Before bagging, the orchard needs to be thoroughly disinfected, spraying once every three days, for two sprayings. After the liquid medicine dries, bagging can begin.
The above is the orchard management technology for growing lemons. Manage the orchard well, reduce sources of disease, and lower the incidence of disease. To give lemons a good growing environment, another thing to pay attention to is the prevention and control of pests and diseases. No matter what pest or disease it is, if it is not handled and prevented in time, it will lead to a large reduction in orchard yield, a rapid decline in quality, and may even result in total crop failure.
