Key Points and Methods of Fertilization Techniques for Shatang Mandarin

Shatang mandarin is a type of mandarin that currently sells relatively well on the market and has been widely planted in China. Generally speaking, fertilization techniques are very crucial among cultivation techniques, so do you know how to fertilize during the cultivation of shatang mandarin to ensure high yield and high quality? Follow along as the editor briefly explains it below.

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, which is what people call about fifteen to twenty days before the spring shoots sprout. At this time, we mainly use nitrogen fertilizer, and according to the growth condition of the shatang mandarin trees, reasonably control the amount of nitrogen fertilizer to avoid excessive growth of spring shoots. Finally, improve and adjust the soil. Quicklime powder can be used together with foliar fertilizer. For foliar fertilizer, borax, magnesium sulfate, etc. can be used.

2. Flower-promoting and fruit-preserving fertilizer

Flower-promoting and fruit-preserving 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 shatang 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 the key to increasing the yield of shatang mandarin. During this period, we mainly use nitrogen fertilizer, combined with organic decomposed fertilizer, 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 the method of deep trench burying, and it should be done 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 shatang mandarin trees, improve cold resistance for flower bud differentiation, and increase the yield of shatang 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 shatang mandarin trees, such as old trees, young trees, and trees in full bearing period, so as to facilitate the absorption and utilization of nutrients by the tree roots, and improve the yield and quality of the trees in the coming year.

The above are the fertilization techniques for shatang mandarin trees. Here the editor mainly discusses the fertilization techniques for bearing trees, while the fertilization techniques for young trees are also different from it. Young trees mainly promote the growth of the fruit trees, so fertilization needs to be carried out multiple times a year, adhering to the principle of frequent application and thin fertilizer. The editor's sharing for today ends here. I hope it can help everyone.
