Planting management technology of longan

Longan is a very popular fruit, and its planting area is also very extensive in our country. Longan now has a large market demand, so the demand for output is getting higher and higher. When planting longan, the management work is closely related to the output, so we must do a good job in longan management. So the editor below brings you the planting management technology of longan, let's have a look!

1. Water and fertilizer management

The nutritional demand of longan is very large, so we must pay attention to fertilization when planting longan. The first topdressing work should be carried out when the spike grows to about 11 cm to promote the growth of flowers and increase the number of flowers. Then fertilize again after the physiological fruit drop, and control the amount of topdressing according to the amount of fruit hanging on the fruit tree. Finally, the extra-root topdressing should be carried out reasonably according to the growth of longan trees to meet the nutrition needs of longan growth. Then we should also pay attention to control moisture, moisture should not be too much, to prevent stagnant water leading to retting roots, but also timely watering in case of drought to ensure the normal growth of the fruit.

2. Thinning flowers and fruits

The work of flower thinning and fruit thinning is also very important for the growth of longan. It is necessary to start flower thinning when the flower ear development of longan tree is completed in March every year. Then thinning fruit is carried out when the fruit grows to the size of soybeans. The flower thinning objects are mainly weak growth, diseases and insect pests and all kinds of old ears, so as to avoid consuming too much nutrition and promote the fruit. Then more thinning should be done at the top of the crown to prevent the tree from falling due to too much fruit. Fruit thinning should be based on ears with less fruit, and if there are too many fruits per ear, lateral ears should be removed to prevent excessive fruit setting leading to undernutrition and affecting longan yield.

3. Reasonable pruning

When planting longan, you should also do a good job of pruning. First of all, the first pruning is carried out with the flower thinning work in March every year. At this time, the pruning objects are mainly old withered branches, pest branches and over-long and over-dense branches, so as to control the number of inner branches. Prevent excessive consumption of nutrients, improve the permeability of fruit trees, and promote longan to blossom and bear fruit. Then another summer cutting work is carried out in the summer, together with the fruit thinning work. Remove the thin and poor spring shoots to provide sufficient nutrition for the summer shoots.

4. Pest control

Finally, there is longan pest control work, longan pest control work is also we can not be ignored. First of all, we should select excellent varieties with strong disease resistance, and then do a good job in management, cut off diseased branches and diseased trees, strengthen prevention, and improve the disease resistance of fruit trees. And in the process of planting, we should often observe the growth of longan trees, when abnormal conditions are found, we should find out the specific reasons in time, and then make corresponding treatment to prevent the expansion of the damaged area and protect their own planting benefits.

The above is a brief introduction of longan planting management technology. The management of longan has a great influence on its yield and fruit quality. Therefore, we must pay attention to do a good job in management to avoid some unnecessary losses. That's all for today's introduction. This article is for reference only. I hope it can help you all.
