Fertilization techniques of Orange trees

Oranges are one of the best-selling fruits on the market. They taste sweet and contain high vitamins. If you want to have a high yield of oranges, of course, fertilizing is an important step. Today, the editor will introduce to you the fertilization technology of orange trees.

1. Apply sufficient base fertilizer

Orange is a deep-rooted plant, and its root system is more developed, so in order to promote its root system to develop and meet the needs of its whole growth period, it is necessary to combine ploughing and applying base fertilizer before planting, generally applying 3000-4000 kg of mature organic fertilizer per mu. When ploughing, it will be buried in the soil, and when ploughing, it should be turned deeply, so as not to bury the fertilizer too shallow, causing the root system to extend upward, which is disadvantageous to the growth of the plant.

2. Topdressing of young trees

The main purpose of young tree stage is to promote seedling growth, cultivate solid branches and skeleton branches, speed up the formation of tree crown, and lay the foundation for early fruit. therefore, fertilization in young tree stage is mainly nitrogen fertilizer, combined with appropriate amount of phosphorus and potassium fertilizer. the application of nitrogen fertilizer is mainly in spring, summer and autumn, about 350-600 grams of urea is applied per seedling, and the amount of fertilizer is increased year by year with the increase of tree age. Among them, the summer shoot is the most exuberant period of the plant, and it should be reapplied at this time.

3. Fertilization for adult trees

After the orange tree enters the fruiting stage, the purpose is to continue to expand the crown and obtain high yield. at this time, fertilization is to adjust the balance of vegetative growth and reproductive growth of the plant. therefore, factors such as soil, climate, tree potential and yield should be taken into account when applying fertilization. generally, flowering is the most important thing for orange growth and development. the quality of flowers affects the yield of the current year, and also has a certain impact on the annual yield of oranges. Therefore, at this time, the main application of quick-acting chemical fertilizer, combined with organic fertilizer, fertilization time is from February to March, the amount of fertilizer accounts for about 30% of the total fertilization in the whole year, topdressing 2-3 times in the fruit period to ensure that the fruit has enough nutrients to grow, in July-August, the application of available chemical fertilizer, combined with organic fertilizer, accounts for about 35% of the total fertilization in the whole year.

4. Extra-root fertilization

Extra-root topdressing, also known as foliar fertilization, can quickly provide nutrients for plants, usually using a mixture of different fertilizers to meet the comprehensive requirements of nutrients for orange growth. Generally speaking, urea, superphosphate, calcium potassium sulfate and other mixed solution spraying, spraying in the fruit stage has obvious yield-increasing effect, but also can improve the quality of fruit.

If oranges want to have a high yield, they still need to make more efforts on fertilization. do the growers know about the fertilization technology of orange trees arranged by Tuliu.com?
