The latest course on Management techniques and methods of Orange Young trees

Orange is one of the four famous fruits in the world, originating in the southeast of China. It is a kind of citrus of Rutaceae. It has a wide planting range. The management of young orange trees is related to the future tree vigor and yield. How do you manage young orange trees? Let's get to know each other.

1. Soil management

If you want young trees to grow healthy, you must find ways to promote its root growth, you can enlarge the hole to improve the soil, in the fruit outside the excavation of 1~1.2 meters long, 40~50 cm wide, 40~50 cm deep fertilization pit. Sufficient fertilizer is applied to each plant, which is beneficial to root growth. Deep ploughing and soil improvement shall be carried out 1-2 times a year in combination with deep fertilization, and green manure shall be planted in two seasons in the interrow land, intertillage and weeding shall be carried out 3-4 times a year, tree tray covering shall be done well in high temperature and drought, and drainage shall be done well in the garden in rainy season.

2. Fertilization

1-3 The annual tree is the growth period, at this time, fertilization is mainly to enhance the vegetative growth of the tree body, promote the development of healthy branches, and make it rapidly expand to form a high-yield tree. Fertilization should be applied frequently, thinly, eat less and eat more meals, mainly nitrogen fertilizer, properly combined with phosphorus and potassium fertilizer principles, available thin decomposed bran water +0.1%-0.3% urea or compound fertilizer solution drenching, every 15-20 days, with the age of growth, the dosage from small to large, concentration from thin to thick. Every year, according to the growth period of young trees, topdressing should be carried out to promote the growth of healthy branches. When the new shoots turn green, potassium dihydrogen phosphate foliar fertilizer should be sprayed in combination with pest control to promote the aging of new shoots.

3. Shaping and pruning

Young trees are also a stage of young tree management, through pruning to promote crown increase, shape good tree shape, lay the foundation for high yield, summer orange should adopt natural garden head tree shape. Trunking is carried out at the height of 30~40 cm of trunk. After new shoots germinate, 3~4 branches with strong growth and uniform distribution are selected as main branches, and each main branch is equipped with 2~3 auxiliary main branches to form a good crown skeleton with strong bearing capacity. In addition, it is necessary to wipe buds and control shoots in time. After the first batch of shoots are mature, the young trees planted in the same year should be wiped out during summer and autumn shoots, so as to make the new shoots neat and robust, and reduce the damage of leaf miner moths and aphids. In addition, the remaining weak branches and improper long branches, cross branches and diseased branches will be cut off.
