The latest course on fertilization techniques and methods of sugar tangerine

Sugar orange is a kind of orange with relatively good sales in the market, and it has been widely planted in our country. Generally speaking, the fertilization technology in the planting technology is very critical, so do you know how to apply fertilizer in the process of planting sugar orange to ensure high yield and high quality? Let's follow the editor to learn.

1. Promoting shoot fertilizer in spring

Spring shoot fertilizer can also be referred to as spring fertilizer, which is usually carried out during the period from the end of January to the beginning of February, that is, about 15 to 20 days before spring shoots sprout. At this time, we mainly use nitrogen fertilizer for tooth decay, and according to the growth of sugar orange trees, we should reasonably control the amount of nitrogen fertilizer to avoid excessive growth of spring shoots. Finally, the soil can be improved and adjusted, and the lime powder can be used together with foliar fertilizer. Foliar fertilizer can use borax, magnesium sulfate and so on.

2. Fertilizer for promoting flowers and protecting fruits

Fertilizer for promoting flower and protecting fruit is actually a fertilization in spring, usually from the end of March to the beginning of April every year. We use the right amount of compound fertilizer, which can promote flower blooming and flower fade, and can effectively improve the fruit setting rate of sugar orange. In general, the amount of compound fertilizer used per plant is about three jin, which is carried out by means of extra-root fertilization.

3. Promoting shoot fertilizer in autumn

The main purpose of promoting shoot fertilizer in autumn is to cultivate fruiting mother branches, and the leaves of fruiting mother branches are the key to increase the yield of sugar orange. During this period of time, we are mainly based on nitrogen fertilizer, and combined with organic rot fertilizer in about half a month before the shoot, so as to ensure that the shoot is even. Secondly, we can also use some chicken manure properly, buried in deep trenches, and at least one and a half months or two months in advance, so that it can play a role in the growth of autumn shoots.

4. Late maintenance fertilizer

Later conservation fertilizer is generally carried out around November every year, it is mainly to restore the growth of sugar orange trees, and improve the ability to protect against the cold for flower bud differentiation and increase the yield of sugar orange in the coming year. Generally speaking, it needs to be carried out in two stages, mainly with soil miscellaneous fertilizer, organic fertilizer or compound fertilizer combined with phosphorus and potassium fertilizer. At the same time, we also need to transport nutrients reasonably according to the different periods of old trees, young trees and full-bodied fruit trees, which is beneficial to the absorption and utilization of nutrients by the roots of fruit trees and improve the yield and quality of fruit trees in the coming year.

The above is the fertilization technology of sugar orange trees, here the editor mainly talks about the fertilization technology of fruit trees, and the fertilization technology of young trees is also different from it, young trees are mainly to promote the growth of fruit trees, so it is necessary to apply fertilizer many times a year and adhere to the principle of applying thin fertilizer frequently. The editor's sharing ends here today. I hope I can help you all.
