Topdressing technology of ginger

Ginger is a very common side dish in us, and it is welcomed by many people. But also has divergent antiemetic, antitussive and other effects. It is planted all over our country, and topdressing is essential when planting ginger. When topdressing, we should adjust the topdressing method reasonably according to the different growth periods of ginger. So how exactly should it be done? The following editor brings you the topdressing technology of ginger, let's have a look!

1. Base fertilizer

Base fertilizer is the first fertilizer to be carried out in planting ginger. We should apply fertilizer according to the law of ginger's demand for nutrition, because ginger has a greater demand for nutrition in the middle and later stage, so the base fertilizer should be based on organic fertilizer. High-quality mature farm manure 550kg should be applied per mu before planting. Then, when planting, the method of hole application is used to apply the right amount of cake fertilizer to supplement the right amount of compound fertilizer. If there are not enough trace elements in the soil, then we should also apply an appropriate amount of trace element fertilizer, such as zinc sulfate, borax and so on.

2. Topdressing at seedling stage

The growth of ginger in the seedling stage is relatively small, and the demand for fertilizer nutrition is not very large. However, the growth cycle of ginger seedlings is relatively long, so in order to ensure the robust growth of seedlings, or appropriate fertilization. Generally, when the seedlings grow to about 30cm height, and grow two or so small branches. It is necessary to start topdressing, which is also the first topdressing work in the growth process of ginger. It is generally called strong seedling fertilizer, topdressing fertilizer can be ammonium sulfate-based, the amount should not be too much, generally controlled in 18kg/ mu or so.

3. Topdressing in the fork stage

The growth turning point of ginger is around the Beginning of Autumn. At this time, the growth rate of ginger is accelerated, and the demand for nutrition will expand. Therefore, in order to increase the amount of fertilizer application, in order to ensure the yield of ginger, it is necessary to re-apply organic fertilizer to promote the robust growth of plants and provide sufficient nutrition for the expansion of ginger rhizomes. Generally speaking, fertilizer is mainly cake fertilizer and farm fertilizer, and then water-soluble fertilizer is applied in the form of drip irrigation. While supplying basic elements such as nitrogen, phosphorus and potassium, we should also appropriately supplement trace elements such as boron and zinc to provide comprehensive nutrition for ginger.

4. Topdressing during expansion period

The growth of ginger after entering the expansion period is very important. If the nutrition is insufficient, it will directly affect the expansion of ginger and have a great impact on its yield and quality. Generally speaking, when the plant grows into seven branches, ginger enters the expansion period. After entering the expansion period, it is necessary to apply strong ginger fertilizer in time according to the growth of ginger. The main fertilizer should be potash fertilizer, which should be applied for about 3 times, and the type of fertilizer should be dominated by a large number of elements to promote the normal expansion of ginger.

The above is a brief introduction to the topdressing technology of ginger. Topdressing in ginger planting is very important. We must ensure that the fertilizer demand of ginger is met and the yield is increased. That's all for today's introduction. This article is for reference only. I hope it can help you all.
