Detailed Explanation of the Key Cultivation Techniques for Spring Jian Citrus
Spring Jian, or Spring Jian citrus, commonly known as papagan, has crisp and tender flesh that melts in the mouth, is refreshingly sweet, with few or no seeds, and produces high yields. So, what are the Spring Jian cultivation techniques?
1. Site Selection and Orchard Establishment
The site should be chosen on land with deep soil and medium-to-high fertility to establish the orchard. It is most suitable to select high-quality, legitimate nursery stock from Sichuan citrus seedling wholesalers.
2. Reasonable Close Planting of Young Trees
The planting density for young trees is about 80 trees per mu, which helps increase early-stage yields. After the canopy closes in, every other tree should first be pruned back and then removed, leaving about 40 permanent trees per mu.
3. Fertilizer and Water Management
During the young tree stage, apply fertilizer lightly and frequently. After entering the full production period, strengthen fertilizer and water management, especially applying heavy fruit-swelling fertilizer in June to July. The post-harvest fertilizer should be applied earlier, in October, mainly using farmyard manure and organic fertilizer.
4. Shaping and Pruning
Spring Jian branches and shoots tend to grow upright, with strong branching and shoot-forming ability. When shaping and pruning young trees, attention should be paid to combining an open tree form with thinning and shortening of branches, to improve branch quality and increase ventilation and light penetration.
5. Flower and Fruit Management
Spring Jian has a very strong fruiting ability, so attention should be paid to fruit thinning. The best time is after the second physiological fruit drop in late June, removing small fruits, diseased fruits, insect-damaged fruits, deformed fruits and overly crowded fruits to ensure large fruit size and high quality; the wholesale price of Sichuan citrus seedlings is around 20 yuan, with good varieties and high yields.
6. Pest and Disease Control
Spring Jian has strong resistance to canker and decline diseases, but is sensitive to anthracnose, especially after heavy fruiting, when weak trees and weak branches are more affected, and timely control should be carried out. In spring and summer, mite control should be strengthened, and in autumn and winter, attention should be paid to the control of rust mites.
Spring Jian citrus is an excellent hybrid citrus variety with good quality, is not difficult to cultivate, and has had a good market outlook in recent years. Friends who are interested can try planting it.
