The Latest Longan Planting and Management Techniques: A Tutorial
Longan is a very popular fruit, and its planting area in our country is also very extensive. Longan now has a relatively large market demand, so the requirements for yield are also getting higher and higher. When planting longan, management work is closely related to yield, so the management of longan must be done well. Then the editor below brings you the planting and management techniques for longan, let's take a look!
1. Water and Fertilizer Management
The nutritional demand of longan is very large, so when planting longan, attention must be paid to doing a good job of fertilizing. The first topdressing should be carried out when the flower spikes have grown to about 11 cm, to promote flower growth and increase the number of flowers. Then, after the physiological fruit drop, topdress again, and control the amount of topdressing according to the fruit load of the tree. Finally, according to the growth condition of the longan tree, reasonably carry out foliar topdressing to meet the nutritional needs of longan growth. Then we must also pay attention to controlling water properly. Water should not be too much, to prevent waterlogging from causing root rot, but in case of drought, water should also be given in time to ensure normal fruit growth.
2. Flower Thinning and Fruit Thinning
Flower thinning and fruit thinning work is also very important for the growth of longan. In March every year, when the development of the longan tree's flower spikes is completed, flower thinning should begin. Then, when the fruits grow to the size of soybeans, carry out fruit thinning. The targets for flower thinning are mainly weak-growing, pest- and disease-damaged, and various old spikes, to avoid consuming too much nutrition and promote fruit set. Then more thinning should be done at the top of the canopy to prevent excessive fruit set from causing a decline in tree vigor. Fruit thinning should mainly target fruit spikes with few set fruits. If a single spike sets too much fruit, the side spikes should be thinned to prevent excessive fruit set from causing insufficient nutrition and affecting longan yield.
3. Reasonable Pruning
When planting longan, pruning work should also be done well. First, in March every year, carry out the first pruning together with flower thinning. At this time, the main pruning targets are old dead branches, pest- and disease-damaged branches, and overly long and dense branches, and the number of inner canopy branches should be controlled. This prevents excessive nutrient consumption, improves the tree's ventilation and light penetration, and promotes longan flowering and fruiting. Then in summer, carry out another summer pruning together with fruit thinning. Thin out weak and poorly growing spring shoots to provide sufficient nutrition for the sprouting of summer shoots.
4. Pest and Disease Control
Finally, there is the prevention and control of longan pests and diseases. The prevention and control of longan pests and diseases is also something we cannot ignore. First, we should choose excellent varieties with strong disease resistance, then do a good job of management, cut off diseased branches and diseased trees, strengthen prevention, and improve the disease resistance of the fruit trees. In addition, during the planting process, we should often observe the growth condition of the longan tree. When abnormalities are found, promptly identify the specific cause and then make the corresponding treatment, to prevent the affected area from expanding and protect your own planting benefits.
The above is a brief introduction to longan planting and management techniques. The management work for longan has a very large impact on its yield and fruit quality. Therefore, everyone must pay attention to doing a good job of management to avoid some unnecessary losses. That is all for today's introduction.
