2. Cultivation techniques of Ponkan

1. Expanding holes to improve soil

According to the characteristics of high yield, many fruits, long fruit setting time and consuming a lot of nutrients and water, it is necessary to enlarge and press the transplanted Ponkan seedlings. The hole is 2 meters long, 1 meter wide and 60-80 cm deep. The hole is divided into three layers of landfill grass, rotten farm manure and cake fertilizer, 150 kg per hole, 100 kg of mature farm manure, 5 kg of cake fertilizer, 1 kg of hair and 1 kg of lime.

2. Fertilization

Organic fertilizer is the main fertilizer, combined with compound fertilizer. During the vigorous root growth period from April to May every year, 667 square meters apply 900-1500 kg of mature natural farm manure (such as chicken manure, pig manure, cow manure, sheep manure, human feces, urine or biogas liquid, etc.). The strip fertilizer method was used, that is, strip ditches were opened between rows and plants, the depth of the ditch was about 30 cm, and filled with soil after fertilization. For example, rotten human feces and urine or biogas liquid can be evenly dug 6-10, 20-30 cm holes slightly outside the crown dripping line, and the soil will be covered after fertilization for human feces and urine or biogas liquid to dry. According to the fruit tree with a yield of 80 kg per 667 square meters, compound fertilizer (N: P: K = 15:15:15) was applied 3-4 times a year, each time 2-3 kg.

3. Pruning

Combined with winter cutting to cut off the central trunk and redundant sub-main branches and side branches, suppress the top dominance, promote the development of the surrounding branches, make the main stem and the ground 60-70 °, the secondary main branch and the main branch 10-15 °, wipe off the tender shoots in summer, cut off the overgrown branches and overdense branches at the top of the crown and the inner chamber, and the height is controlled between 3-4 meters. Pruning the tree into a happy shape can not only improve the light exposure of the tree, increase the fruiting area, but also reduce the relative humidity, reduce diseases and insect pests, dwarf the tree, and facilitate agricultural operation.

4. Pest control

Dormant period is one of the best seasons for prevention and control. As some pests will enter the dormant period in a certain season, the speed of reproduction and spawning will be greatly reduced, so producers can use this time to carry out comprehensive pest control work to lay a solid foundation for control work.

The planting adaptability of Ponkan is very wide, it can be planted in most areas of the country, and the yield per mu is high. Interested growers can try to plant according to their own local planting conditions.
