Detailed Explanation of Key Points of Longan Planting and Management Techniques
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 requirement for yield is also getting higher and higher. When planting longan, management work is closely related to yield, so the management work of longan must be done well. Then the editor below brings you the planting and management techniques of longan, let's take a look together!
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 in fertilization. The first topdressing work should be carried out when the flower spikes grow to about 11 cm, to promote flower growth and increase flower quantity. Then topdress again after the physiological fruit drop, and control the topdressing amount according to the fruit load of the tree. Finally, according to the growth condition of the longan tree, reasonably carry out foliar topdressing work to meet the nutritional needs of longan growth. Then we should also pay attention to controlling water well; water should not be too much, to prevent waterlogging from causing root rot, but in case of drought, water timely as well to ensure normal fruit growth.
2. Flower and Fruit Thinning
Flower and fruit thinning work is also very important for the growth of longan. In March every year, when the flower spike development of the longan tree is completed, flower thinning work should begin. Then when the fruit grows to the size of a soybean, carry out fruit thinning work. The targets of flower thinning are mainly weak-growing, diseased and pest-infested, and various old spikes, to avoid consuming too much nutrition and promote fruiting. Then more thinning should be done at the top of the canopy to prevent excessive fruit set from causing tree vigor decline. Fruit thinning should mainly focus on fruit clusters with few fruits set. If each single cluster sets too much fruit, the side clusters 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 work. At this time, the main pruning targets are old dead branches, diseased and pest-infested branches, and overly long and dense branches, to control the number of inner canopy branches. Prevent excessive nutrient consumption, improve the tree's ventilation and light transmission, and promote longan flowering and fruiting. Then carry out another summer pruning in summer, together with fruit thinning work. Thin out weak and poorly growing spring shoots to provide sufficient nutrition for the sprouting of summer shoots.
4. Disease and Pest Control
Finally, there is the disease and pest control work for longan. The disease and pest control work for longan is also something we cannot ignore. First, we should choose excellent varieties with strong disease resistance, then do a good job in management, cut off diseased branches and diseased trees, strengthen prevention, and improve the disease resistance of the fruit tree. And during the planting process, we should often observe the growth condition of the longan tree. When abnormalities are found, promptly identify the specific cause, then make 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 of longan has a very large impact on its yield and fruit quality. Therefore, everyone must pay attention to doing a good job in management work to avoid some unnecessary losses. That's all for today's introduction.
