Key Points of Field Management for Ponkan Cultivation

Ponkan is a citrus variety of Rutaceae, with thin, sweet skin, rich aroma, many fruit juices and sweet and delicious. There is a very large planting area in the south of our country. And Ponkan also has some medicinal effects, can supplement the human body's vitamins and other nutrients, welcomed by many people. Now that more and more people are growing, how to manage the cultivation of mandarins? The following editor brings you the key points of Ponkan field management, let's have a look!

1. Soil management

Soil has a great effect on the growth of Ponkan, although it can grow on most of the soil. However, the quality of the soil is directly related to the yield and fruit quality of Ponkan. Therefore, before we plant ponkan, we should choose the soil that is permeable and fertile, deep and loose, and normal drainage and irrigation, and then do a good job of soil preparation and disinfection. After planting, it is necessary to turn deeply and expand the hole once a year to promote soil ripening. When we should pay attention, we should not interplant corn and other high-stem crops in the orchard, but should intercropping reasonably and do a good job of intercropping and weeding.

2. Scientific fertilization

The fertilization of Ponkan is mainly soil fertilization, supplemented by foliar fertilizer, and various fertilization methods can be used, such as furrow application, strip application, hole application and so on. Control the amount of fertilizer and the type of fertilizer according to the age of the tree. For example, when applying fertilizer to young trees, we should follow the principle of applying a small amount of fertilizer, mainly nitrogen fertilizer, combined with appropriate amount of phosphorus and potassium fertilizer. Fertilization should be applied at least 5 times except in winter. On the other hand, the fertilization of adult trees should be applied about four times in the period of germination, flower and fruit, fruit harvest and so on. The amount of fertilizer applied in each period is different, for example, it is about 3 jin per tree in the budding period, and the amount of fertilizer should be adjusted reasonably.

3. Rational watering

Water is also very important to the growth of ponkan. When planting mandarins, we should pay attention to regular watering to avoid soil drought and timely watering in times of drought. But the amount of water should not be too much, just keep the soil moist. If the rainy season or too much watering leads to stagnant water in the field, then drainage should be done in time to avoid retting roots to affect the growth of Ponkan. Reduce the amount of flowers and fruits of Ponkan and affect the planting efficiency. In the time of high temperature in summer, because the rate of water evaporation is fast, it is necessary to increase the amount of water or cover straw to reduce the rate of water evaporation in summer.

4. Proper pruning

Ponkan has a large tree shape, so we also have to do a good job of pruning in planting. Pruning should be adjusted reasonably according to the tree age. When pruning young trees, light pruning should be given priority to, and lengthening branches and main branches in the middle should be selected to make a severe truncation. Adjust the growth direction of cutting buds to ensure the balanced growth of each main branch. Then it is necessary to properly delete the branches that are too dense. If it is the first fruit tree, then it is necessary to continue to cut short the extended branches of the backbone. Erase summer shoots and promote the ugliness of autumn shoots, mainly by ring cutting, root cutting and other methods.

The above is a brief introduction to the main points of field management of ponkan planting. The field management of Ponkan is very important, which directly affects the yield of Ponkan, so it is closely related to its own interests, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
