Detailed Explanation of Field Management Techniques for Chucheng Oranges
Chucheng orange is an orange variety created by the famous entrepreneur Chu Shijian, and it was named Chucheng orange after him. It was originally a specialty of Yunnan, but as Chucheng orange became more and more famous, it is now also grown to some extent in other tropical provinces in China. Chucheng orange has gradually spread across the country, and many people want to introduce and cultivate it. But do you know how to manage Chucheng orange after cultivation? Below, the editor brings you the key field management points for Chucheng orange. Let's take a look together!

1. Fertilizer and Water Management
Chucheng orange has different nutritional needs at each growth stage. During its young tree stage, fertilization should focus mainly on nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers, and the principle of applying more frequently but in small amounts should be followed. Then, topdressing should be applied once after each new shoot sprouting and pruning. Generally, about 5 topdressings are needed each year. Then, during important periods such as the flowering and fruiting stage and the expansion stage, foliar fertilizer should also be sprayed appropriately. In spring, we should water in time to keep the soil moist and meet the water needs of Chucheng orange. However, note that water should not be excessive. In high-temperature and high-humidity environments such as summer, attention should also be paid to drainage work to prevent pests and diseases from affecting the growth of Chucheng orange.
2. Shaping and Pruning
Like fertilizer and water management, shaping and pruning methods for Chucheng orange differ by tree age. During the young tree stage, about 3 main branches should be cultivated, with about 2 side branches retained on each main branch. The pruning method should focus mainly on letting shoots grow and pinching the tips, so as to cultivate good scaffold fruiting branches. Then, for adult trees, thinning and contraction pruning methods should be used to improve the tree's ventilation and light penetration and maintain a good tree shape. Pruning is generally carried out before the flower bud stage, and the pruning method should be controlled according to tree vigor and the amount of flowers and fruit. After harvest, overly long and dense branches as well as poor branches such as diseased and pest-damaged ones should be removed in time. Then, healthy fruiting branches should be appropriately shortened to promote fruiting the following year and increase yield.
3. Flower and Fruit Management
When planting, in order to prevent damage to the roots of Chucheng orange trees, fertilization should be done during the color-turning stage, and foliar fertilizers such as trace elements should be sprayed appropriately. Drainage work should be done well to prevent pests and diseases. The tree should not retain too much fruit, and poor fruits such as small fruits and diseased and pest-damaged fruits should be removed in time. This prevents excessive nutrient consumption and promotes the growth of normal fruits. Then, growth regulators and other agents should be sprayed appropriately for flower and fruit preservation measures to reduce physiological fruit drop. The growth of summer shoots should be controlled, and buds should be appropriately removed to increase the fruit-setting rate. During physiological fruit drop, nitrogen fertilizer application should be stopped.
4. Harvesting and Storage
When harvesting, we should control the harvest time according to different intended uses to ensure the commercial value of the fruit. For example, if the fruit needs to be stored and transported after harvest, then it should be harvested when the fruit is about 80% ripe. During harvest, mechanical damage to the fruit should be prevented, as it can cause wounds on the fruit and reduce storability. If the fruit is to be stored after harvest, then it should be soaked in a solution such as carbendazim for about half a minute. After drying it, put it into plastic bags, turn it over about once every half month, and promptly pick out any rotten fruit.
The above is a brief introduction to the key field management points for Chucheng orange. Field management of Chucheng orange has a great relationship with its growth and yield. Therefore, if we introduce and cultivate it, we must learn the management techniques well so that we can ensure our planting benefits. That is all for today's introduction.
