How to manage young orange trees? Latest technical method tutorial
Orange is one of the four famous fruits in the world, native to the southeastern part of China, a citrus of the Rutaceae family, and widely cultivated. The management of young orange trees affects the future tree vigor and yield. So how should young orange trees be managed? Let's take a look together.
1. Soil management
To make young trees grow robustly, you need to find ways to promote their root growth. Through the method of expanding the planting hole and improving the soil, dig fertilization pits 1-1.2 m long, 40-50 cm wide, and 40-50 cm deep along the outer edge of the orchard. Applying sufficient fertilizer to each tree is also beneficial to root growth. Each year, carry out deep plowing and soil improvement 1-2 times in combination with deep fertilization. At the same time, plant two seasons of green manure in the inter-row spaces. Carry out inter-row cultivation and weeding 3-4 times each year. During periods of high temperature and drought, do a good job of mulching the tree disk, and during the rainy season, do a good job of drainage in the orchard.
2. Fertilization
Trees 1-3 years old are in the growth period. At this time, the main purpose of fertilization is to enhance the vegetative growth of the tree body, promote the sprouting of robust shoots, and enable them to rapidly expand and form a high-yielding tree shape. Fertilization should follow the principles of frequent application, light application, small meals more often, mainly nitrogen fertilizer, and appropriate combination with phosphorus and potassium fertilizer. You can use diluted decomposed bran manure water + 0.1%-0.3% urea or compound fertilizer solution for drenching, once every 15-20 days. As the tree age increases, the amount used goes from small to large, and the concentration goes from dilute to concentrated. Each year, topdressing should be carried out according to the growth period of the young trees to promote the sprouting of robust shoots. When new shoots turn green, spray potassium dihydrogen phosphate foliar fertilizer in combination with pest and disease control to promote the maturity of new shoots.
3. Shaping and pruning
Young trees are also a stage in young tree management. Through pruning, the canopy is enlarged and a good tree shape is built, laying the foundation for high yield. Summer orange is suitable for adopting a natural round-headed tree shape. Cut the top at a trunk height of 30-40 cm to set the trunk. After new shoots sprout, select and retain 3-4 robust, evenly distributed shoots on the trunk as main branches. Each main branch is configured with 2-3 secondary main branches to form a good, strong-load-bearing canopy framework. In addition, timely remove buds and control shoots. For young trees planted in the same year, after the first batch of shoots sprouts and matures, during the period of releasing summer and autumn shoots, the sporadic new shoots that sprout early should be removed to achieve unified shoot release, so that new shoots sprout neatly and robustly and damage from leafminers and aphids is reduced. In addition, the remaining weak branches and improperly positioned water sprouts, crossing branches, and diseased and pest-damaged branches should be cut off.
