How to Grow Chucheng Oranges? A Detailed Explanation of the Key Points of Chucheng Orange Cultivation Techniques
Chucheng orange is a type of sweet orange native to Yunnan. Chucheng oranges have a very high sugar content and are rich in vitamin C, giving them high nutritional value. Compared with other oranges, although the peel is thick, it is easier to peel off, so it became very popular as soon as it hit the market. So how do we grow Chucheng oranges? Today, the editor brings you the cultivation techniques for Chucheng oranges. Let's take a look below!
1. Site Selection and Orchard Establishment
Chucheng oranges are suitable for growing in fertile, loose, deep soil rich in organic matter. After selecting the site, the soil should be deep-plowed. If conditions permit, mechanical deep plowing can be carried out. When deep plowing, attention should be paid to building good pedestrian pathways to facilitate later management. Prepare water conservancy facilities, then six months before planting, control the planting density and dig the planting trenches, then carry out soil maturation work on the soil in the planting trenches. After successful maturation, fill the planting trenches with topsoil, then apply organic fertilizer, organic matter, etc. in layers onto the topsoil to improve soil fertility.
2. Seed Selection and Seedling Raising
When selecting seeds, choose high-yielding varieties with large fruit, abundant juice and few instances of fruit drop and fruit splitting. The propagation method of Chucheng oranges is generally mainly grafting, and the rootstock for grafting is mainly trifoliate orange. Cultivating robust seedlings is the key to ensuring high and stable yields of Chucheng oranges. The seedlings must have well-developed roots, and after grafting, the graft union should be promoted to heal as quickly as possible. When the grafted seedlings grow to about 45 cm and have about 4 branches, carry out temporary planting work. When temporary planting, it should be done with soil, choosing soil with sufficient sunlight, sufficient water and sufficient fertility, preferably near the permanent planting orchard to facilitate transplanting and permanent planting.
3. Timely Permanent Planting
The size of the planting hole is mainly determined by the size of the seedling, as long as it can ensure full contact between the seedling roots and the soil. If no base fertilizer has been applied, then the planting hole should be slightly enlarged to facilitate fertilization work after planting. The best time for permanent planting of Chucheng oranges should be around September each year, though it can also be done in early spring and early summer. When planting, straighten out the seedling roots and place them into the planting hole, then fill in soil in layers, paying attention to the depth and keeping it moderate. Then cover the roots with a layer of fine soil. After filling with soil, compact and tread the soil around the roots firmly, then water thoroughly, then prune off some branches and leaves, and water about once every 5 days.
4. Field Management
Water and fertilizer are very important for the growth of Chucheng oranges. During the planting process, we should rationally fertilize and water according to the different tree ages of Chucheng orange trees to meet the water and nutrient needs of Chucheng oranges. Then, if the soil in an adult orchard becomes compacted, a cultivation should be carried out once every autumn. Break up the soil compaction, then appropriately expand the planting holes, apply a topdressing of farmyard manure, and improve the soil structure. In addition, the planting spacing of Chucheng oranges is relatively large, so we can appropriately interplant some vegetables between the rows of Chucheng oranges, but tall-stemmed plants must not be planted, to prevent affecting the growth of Chucheng oranges.
The above is a brief introduction to the cultivation techniques of Chucheng oranges. The cultivation of Chucheng oranges is actually quite similar to that of other ordinary oranges. However, we also need to do a good job in management work to ensure the yield of Chucheng oranges, enhance the quality of Chucheng oranges, and improve planting benefits. That's all for today's introduction. This article is for reference only. Thank you everyone for reading and supporting.
