The Latest Fertilization Techniques and Methods Tutorial for Shiranui Mandarin

Shiranui mandarin is a type of mandarin that currently sells relatively well on the market and has already been widely planted in China. Generally speaking, fertilization techniques within cultivation techniques are very crucial, so do you know how to fertilize during the Shiranui mandarin growing process to ensure high yield and high quality? Follow along with the editor below to learn about it briefly.

1. Spring shoot-promoting fertilizer

Spring shoot-promoting fertilizer can also be simply called spring fertilizer. It is generally applied during the period from the end of January to early February, that is, about fifteen to twenty days before the spring shoots sprout. At this time, nitrogen fertilizer is mainly used, and according to the growth condition of the Shiranui mandarin trees, the amount of nitrogen fertilizer should be reasonably controlled to avoid excessive growth of spring shoots. Finally, improve and adjust the soil. Lime powder can be used and applied together with foliar fertilizer. For foliar fertilizer, borax, magnesium sulfate, etc. can be used.

2. Flower-promoting and fruit-setting fertilizer

Flower-promoting and fruit-setting fertilizer is actually a fertilization carried out in spring, generally from the end of March to early April each year. We use an appropriate amount of compound fertilizer, which can promote flowering and flower drop and can effectively increase the fruit-setting rate of Shiranui mandarin. Under normal circumstances, the amount of compound fertilizer used per plant is about three jin, applied by means of root-outside fertilization.

3. Autumn shoot-promoting fertilizer

Autumn shoot-promoting fertilizer is mainly for cultivating bearing mother branches, and bearing mother branches are also the key to increasing the yield of Shiranui mandarin. During this period, nitrogen fertilizer is mainly used, combined with organic decomposed fertilizer and applied about half a month before shoot emergence, so as to ensure uniform shoots. Secondly, we can also appropriately use some chicken manure, applied by deep trench burying, and it should be carried out at least about one and a half months or two months in advance, so that it can have an effect on the growth of autumn shoots.

4. Later-stage maintenance fertilizer

Later-stage maintenance fertilizer is generally applied around November each year. It is mainly to restore the growth vigor of the Shiranui mandarin trees, improve cold resistance for flower bud differentiation, and increase the yield of Shiranui mandarin in the coming year. Generally speaking, it needs to be carried out in two applications, mainly using farmyard manure, organic fertilizer or compound fertilizer together with phosphorus and potassium fertilizer. At the same time, we also need to reasonably supply nutrients according to the different stages of the Shiranui mandarin trees, such as old trees, young trees, and full-bearing trees, which is beneficial to the absorption and utilization of nutrients by the tree roots and improves the yield and quality of the trees in the coming year.

The above are the fertilization techniques for Shiranui mandarin trees. Here the editor mainly talks about the fertilization techniques for bearing trees, while the fertilization techniques for young trees are also different from it. Young trees are mainly to promote tree growth, so fertilization needs to be carried out multiple times a year, adhering to the principle of frequent application and light application. That is the end of today's sharing by the editor. I hope it can help everyone.
