Main points of planting longan

Longan is very common in China, because it has a high nutritional value, and taste sweet and delicious, so it is also welcomed by many people. So now longan also has a large planting area in our country. When planting longan, there are many key points that we need to pay more attention to. So the editor brings you the key points of longan planting today, let's take a look at it!

1. Soil requirements

Longan in most fruits, the requirements of the soil is not very strict. Whether it is dry or sour, it can grow normally. However, it will have a certain impact on its yield, especially in the clay soil at the bottom of the surface sand. Although longan can grow normally, its yield will be seriously affected and its life span will be low, resulting in a decline in planting efficiency. Therefore, it is best to plant longan in a soil with soft soil, sufficient fertility and normal drainage and irrigation. Do a good job of soil preparation and fertilization before planting, and increase the yield of longan as much as possible.

2. Temperature requirement

Temperature is also very important for the growth of longan. Longan generally likes to grow in a warmer climate. Therefore, planting areas should ensure that there is little or no frost in winter, and only in this way can longan grow normally. In general, the suitable growth temperature of longan is about 22 degrees. In winter, the temperature should not be lower than zero. If it is below zero, it can easily cause longan seedlings to freeze to death. Therefore, before planting longan, we should know whether the temperature change in the planting area is suitable for the growth of longan, otherwise we will have to plant longan in a greenhouse.

3. Key points of fat and water

Fertilizer and water management is one of the key points that we need to pay attention to when planting longan. When applying fertilizer, we should pay attention to the application of strong flower and fruit fertilizer as well as foliar fertilizer. Apply a strong flower fertilizer from February to March, and then apply it again in early April. Secondly, strong fruit fertilizer was applied after the first physiological drop of longan tree to before the second physiological drop. In the longan fruit development period, we should pay attention to control moisture, if there is more rainfall, it should be drained in time. At the same time, in case of drought, it is necessary to timely watering and moisturizing to ensure that the fruit can grow normally.

4. Pest control

Pest control is also very important. During the growing period of longan, common diseases and insect pests are frost Phytophthora, anthrax and stink weevil. In the prevention and control of these diseases and insect pests, we should pay attention to control the time and types of chemical control according to the phenological period, occurrence regularity and damage degree of longan trees. It is usually sprayed about 4 times a year. At the same time, an appropriate amount of foliar fertilizer can be added when spraying. It can not only control diseases and insect pests, but also achieve the purpose of topdressing outside the root and protecting flowers and fruits.

The above is a brief introduction to the main points of longan planting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
