The four seasons of the year lie in spring. The management of mixed oranges in spring will affect the benefits of the whole year. At this time, the miscellaneous mandarin in Sichuan has entered the spring shoot and flower bud stage, which is an important period for mandarin mandarin management. During this period, various management work must be strengthened. So how to do it specifically? The management of spring mixed oranges mainly includes spring nutrition management, pruning management, promotion of flowers and flowers, and control of diseases and insect pests.
First, nutrition management Sichuan mixed oranges stayed late, with poor tree vigor. After picking the fruit, the tree needs to be restored in time. For example, after harvesting the fruit in spring and ignorance of the fire, it is recommended that each plant be mixed with water to apply a functional compound fertilizer or a trace element water-soluble fertilizer; foliar spraying with Amino Acid foliar fertilizer and water solution. Then open a ditch outside the drip line of the canopy to promote shoot growth and strong fertilizer. Each plant is applied with biological organic fertilizer + functional compound fertilizer (25: 5: 15) + trace element fertilizer. The specific amount of fertilizer should be based on the size of the tree and the tree. Trend and variety. After fertilization, it is covered with watering to improve soil quality, promote roots and roots, supplement nutrition, and promote spring shoot growth and flowering and fruiting.
2. Spring Pruning Spring pruning needs to be flexibly pruned according to species, tree vigor, and tree size and year. Spring pruning is divided into first cut before flowering and multiple cut after flowering. 1. Initial cut before flowering. If the vegetative growth of the tree is more prosperous, you should delay pruning to make it less tapped and more flowered; if it is weak, you should trim it early to promote its tapping to restore tree vigor; if it is a young tree It should be pruned as early as possible, and some of the fruiting branches should be shortened. Weak, short-strength, and remaining measures should be adopted to reduce the amount of flowers and promote vegetative branches. If it is a young tree, it should be pruned later, with light cutting as the main method to remove dead branches, disease and insect branches, and late autumn shoots. Try to keep the mother branches as much as possible, so as to avoid more shoots and more flowers. 2. Recutting after flowering. For trees with a large amount of flowers, appropriate thinning or short-cutting of some weak flowering and leafless flowering branches will trigger new shoots, making them the fruiting branches of the coming year, while reducing nutritional consumption. When the spring amount is small and the spring shoots germinate too much, the spring shoots should be kept as much as possible, and some spring shoots and vegetative shoots should be removed in time.

3. Promoting flowering and spring blooming stage-flower bud stage, foliar spraying Youfeng + trace element water-soluble fertilizer + 98% potassium dihydrogen phosphate against water, spraying foliar spraying Youfeng + trace elements at intervals of 7-10 days Water-soluble fertilizer + 99% high-purity boron fertilizer is mixed with water solution to supplement phosphorus, potassium, boron and other nutrients to promote flowering and flowering. Fourth, the pest control temperature gradually increased at this stage, the occurrence of pests and diseases is relatively serious, mainly harm spring shoots and flower buds. The main pests and diseases are anthracnose, scab, dermatosis, brown spot and other diseases, and flower buds, red spiders, yellow spiders, aphids, thrips and other pests. Fungal diseases such as anthracnose, scab, dermatosis, brown spot, etc. It is recommended to use Guojianjian, Luolisheng and other agents for prevention and treatment. Red and yellow spiders and other agents are recommended for prevention and control by Guoguang Pesticide, ethizole, spirotetramat, and thiafenone. At the same time, pay attention to the comprehensive and thoughtful spraying. Flower buds should be applied at the beginning of the budding period, that is, before the buds are exposed to white light, with Guoguang propyl bromide. Phoxim is poured on the canopy ground to prevent the emergence of newly emerged adults. During the buds white period, Guoguang can be applied foliarly. Poison arrows are used to prevent and control flower buds. For aphids and thrips, it is recommended to apply foliar application of Guoguang 毙 + 毙 for control. At the same time, care should be taken to rotate the medication to avoid resistance to diseases and insect pests.
The above are the main points for the management of mixed oranges in spring. Although the weather conditions in other areas are different, the growing process is the same. The management can be adjusted according to the actual situation. The above content is for reference only.
