A Detailed Explanation of the Latest Field Management Key Points for Chu Orange
Chu Orange is an orange variety created by the famous entrepreneur Chu Shijian, and it is named Chu Orange for this reason. It was originally a specialty of Yunnan, but as Chu Orange's reputation has grown, it is now also cultivated to some extent in other tropical provinces in China. Chu Orange is now gradually spreading across the country, and many people want to introduce and cultivate it. But do you know how to manage Chu Orange after cultivation? Below, the editor brings you the key points of field management for Chu Orange. Let's take a look!
1. Fertilizer and Water Management
Chu Orange has different nutrient requirements at each growth stage. During its young tree stage, the focus of fertilization is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizers, and fertilization should follow the principle of applying more frequently but in small amounts. Then apply topdressing 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 Chu Orange's water needs. However, note that water should not be excessive either. In summer and other high-temperature and high-humidity environments, attention should also be paid to drainage work to prevent pests and diseases from affecting the growth of Chu Orange.
2. Shaping and Pruning
Like fertilizer and water management, Chu Orange shaping and pruning methods differ according to 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 is mainly shoot release and pinching, to cultivate good backbone fruiting branches. Then, for adult trees, use thinning and contraction pruning methods 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 harvesting, promptly thin out overly long and dense branches as well as poor branches affected by pests and diseases. Then appropriately shorten healthy fruiting branches 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 Chu Orange trees, we should do a good job of fertilization during its color-turning stage and appropriately spray foliar fertilizers such as trace elements. Do a good job of drainage to prevent pests and diseases. The fruit retained on the tree should not be too many, and poor fruits such as small fruits and pest- or disease-damaged fruits should be removed in time. This prevents excessive nutrient consumption and promotes the growth of normal fruits. Then appropriately spray growth regulators and other agents for flower and fruit preservation measures to reduce physiological fruit drop. Control the growth of summer shoots and appropriately remove buds 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 harvesting, then it should be harvested when the fruit is about 80% ripe. During harvesting, prevent mechanical damage to the fruit, which would cause wounds and reduce storability. If the fruit is to be stored after harvesting, soak it in a carbendazim or similar solution for about half a minute. After drying it, place it in plastic bags and turn it over about once every half month. If rotten fruits are found, pick them out in time.
The above is a brief introduction to the key points of field management for Chu Orange. Field management of Chu Orange is greatly related to 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.
