What are the recipes for tangerine fruit-preserving medicine?

Satsuma mandarin is a common fruit with good taste. It is rich in vitamin C and some nutrients necessary for the human body. Therefore, it is also the most common fruit in life. So, have you ever learned about growing satsuma mandarin? How to better preserve the fruit, make the fruit more productive, and be of better and sweeter quality? Please see the following article for specific methods to preserve fruit.

1. Fertilizer and water control

The mandarin orange tree consumes a lot of organic nutrients during the process of germination, flower bud differentiation and flowering, so it is necessary to replenish nutrients in time.

Apply the first flowering-promoting fertilizer to new fruit-bearing trees when buds appear in spring. The amount of fertilizer applied should depend on the number of flowers. If there are few flowers, applying more fertilizer will cause the spring shoots to be over-nourished, affecting fruit retention. Special attention should be paid to foliar fertilization to supplement trace elements, such as boron, coal, magnesium and zinc, in order to strengthen shoots and flowers and reduce bud and flower drop.

Fertilizer should be applied once after the peak flowering period to ensure the nutritional needs of new shoots turning green and small fruits developing. The amount of fertilizer applied this time should also depend on the number of small fruits.

According to practical experience, the total amount of these two fertilizations is: 2-3 kilograms of organic fertilizer for each 1-2 year old tree; 3-4 kilograms of organic fertilizer for each fruit-bearing tree, combined with water and fertilizer.

2. Thinning and controlling shoots

Thinning out shoots refers to the manual removal of a considerable number of nutritious spring shoots and fruitless nutritious branches after the buds appear and the flowers fall of the mandarin oranges, so as to reduce the waste of nutrients in the tree when the spring shoots elongate and turn green. It is not advisable to pick all the treetops, leave a small amount for use in autumn when the time comes.

Shoot control refers to the technical measure of removing the summer shoots that grow from fruit trees during the physiological fruit drop period from mid-May to late June by artificially removing buds and controlling shoots, in order to reduce nutrient consumption and effectively prevent fruit drop. In the work of shoot control, if there is sufficient labor and good fertilizer and water conditions, you can consider releasing summer shoots once. The shoot release should be carried out in late June to early July. If it is released too early, it will affect the fruit drop; if it is released too late, it will affect the growth of autumn shoots. During the summer shoot period, it is necessary to increase the application of fertilizer and water and strengthen the prevention and control of diseases and pests of new shoots. It has been observed that releasing summer shoots once, especially on plants that are just beginning to bear fruit, is beneficial in preventing the fruits from sunburn and in promoting the growth of strong autumn shoots.

3. Shake the flowers regularly

In southern China, there is more rain in early spring, and the petals and filaments of the mandarin oranges often stick to the small fruits after flowering, affecting the photosynthesis of the small fruits. By shaking the flowers regularly, increasing the amount of light received by the small fruits and reducing the breeding of pests and diseases, the orchard can be promoted to produce three-dimensional fruits. Flower shaking usually starts from the peak of flowering, and should be done once every 5-7 days, which has a very good effect in preserving fruit.
