Detailed Explanation of Longan Planting Methods and Key Technical Points
Longan is very common in China because it has high nutritional value and a sweet, delicious taste, making it popular with many people. Therefore, longan now has a very large planting area in China. When planting longan, there are many key points that require our close attention. So today, the editor has brought you the key points for planting longan. Let's take a look together below!
1. Soil Requirements
Among most fruits, longan is actually not very strict about soil requirements. Whether dry or slightly acidic, it can grow normally. However, this still has a certain impact on its yield, especially in soil with sandy loam on the surface and clay at the bottom. Although longan can grow normally, its yield will be seriously affected, its lifespan will be short, and planting benefits will decline. Therefore, we should preferably plant longan in soil that is soft, sufficiently fertile, and has normal drainage and irrigation. Before planting, do a good job of land preparation and fertilization to increase longan yield as much as possible.
2. Temperature Requirements
Temperature is also very important for the growth of longan. Longan generally likes to grow in a relatively warm climate environment. Therefore, the planting area must ensure little or no frost in winter; only in this way can normal growth of longan be guaranteed. In general, the suitable growth temperature for longan is about 22°C. In winter, the lowest temperature must not be below zero degrees. If it is below zero degrees, longan seedlings are very likely to freeze to death. So before planting longan, we must clearly understand whether the temperature changes in the planting area are suitable for longan growth; otherwise, greenhouse planting should be carried out.
3. Key Points for Fertilizer and Water
Fertilizer and water management is one of the key planting points we need to pay special attention to when planting longan. When fertilizing, we should pay attention to applying fertilizer for flower and fruit development as well as foliar fertilizer. In February to March, apply a flower-promoting fertilizer once, and then apply another topdressing in early April. Next, apply fruit-promoting fertilizer after the first physiological fruit drop of the longan tree and before the second physiological fruit drop. During the longan fruit development period, pay attention to controlling water properly. If there is a lot of rainfall, drain water in time. At the same time, in case of drought, water in time to maintain moisture and ensure normal fruit growth.
4. Pest and Disease Control
Pest and disease control is also very important. During the longan growth period, common pests and diseases include downy blight, anthracnose, and stink bugs. When controlling these pests and diseases, we should pay attention to the actual situation such as the phenological period of the longan tree, occurrence patterns, and degree of damage, and properly control the timing and types of chemical control. Usually, spray about 4 times per year. At the same time, when spraying, an appropriate amount of foliar fertilizer can also be added. This can not only prevent and control pests and diseases, but also achieve the purposes of foliar topdressing and protecting flowers and fruits.
The above is a brief introduction to the key points of longan planting. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
