Management techniques of longan seedlings

The seedling period of longan is very long, which usually lasts for several years. The management during this period has become a very important issue. The follow-up growth and yield will have a great impact on this stage. So if we want to plant longan well, how do we manage it at this stage?

1. Irrigation problem

As a tropical fruit, longan tree itself has a high demand for water, and the seedling stage needs to pay more attention to the problem of drainage and irrigation. The root system of longan is mostly concentrated at the bottom of the soil, so the amount of each watering is relatively large, because it has to wait for the water to sink, and if less water does not sink near the root system, it is not conducive to its absorption. Generally speaking, the water demand of spring and autumn can be guaranteed once or twice a month, because there will be natural rainfall, and when there is high temperature and drought, it will increase to once or twice a week, and the humid environment will make the seedlings grow faster.

2. How to topdressing

As the seedling stage has several years, the annual topdressing also has to change, the first few months is thin fertilizer, usually in the second shoot time to start topdressing. Farm manure is the best fertilizer in the initial stage, but it should be treated and fermented, so it is not easy to rot the root system. Farm manure had better mix some water and reduce the concentration before topdressing. At least half a year before topdressing began to use chemical fertilizer, at this time its root base is relatively solid, and then use chemical fertilizer to speed up its growth. Chemical fertilizer is added according to the demand of each stage, and you can start topdressing according to the tree in about 3-4 years.

3. Ploughing and weeding

The root system of longan seedlings is relatively weak, the demand for air can not be easily met, which will affect the growth to a certain extent, which can only be solved by improving the permeability of the soil, so turn the soil deeply on a regular basis. When turning the soil, we should be careful not to hurt its roots. At this time, we can also mix some fertilizers properly, turn the soil and top up the fertilizer together, several times a year, depending on the compactness of the soil. Weeding is not for fear of competing for nutrients with longan seedlings, but at most it can hinder its growth. The main purpose of weeding is to prevent the soil from hardening, and impermeability hinders root development.

4. Disaster prevention

Finally, there is disaster prevention. Longan is a common fruit tree with insect pests and diseases, because its growing environment is easy to induce these things. Diseases generally begin to be prevented when the temperature rises slowly, the first wave of temperature rise is the most prone to disease, and the continuous high temperature weather is the peak of the disease, these two times should focus on prevention. The occurrence of insect pests is mostly concentrated in the fruiting period, and the insects are easy to hide after longan trees bear fruit, so we should do a good job of pest control measures in advance. In terms of natural disasters, we should pay attention to cold and rainstorm weather, it is best to be prepared.

These are some of the management techniques of longan seedlings, the time of seedling stage is 3-4 years, but the time of full fruit stage has obvious changes because of each stage. The well-managed may last for more than ten years, and those who do not pay attention may fall into a trough in a few years, and the impact on earnings will be more obvious in the later stage.
