What Causes Mottled Skin on Ginger? Latest Analysis
Ginger is a very important seasoning when we prepare dishes. It has a very large planting area in our country, and when planting ginger, if management is improper and the ginger becomes infected with bacteria, then mottled skin is very likely to appear, and mottled skin will seriously reduce the commercial value of ginger and the planting benefits. So what causes mottled skin on ginger? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Continuous Cropping
When we plant ginger, we need to do a good job of crop rotation. Ginger is not suitable for continuous cropping. If ginger is planted year after year, then many pathogens and pests will be produced in the soil, and ginger is also very prone to infection by pests and diseases during growth, thus developing phenomena such as mottled skin. Therefore, when planting ginger, we must pay attention to not continuously cropping it. In areas where continuous ginger planting is relatively serious, we should at least rotate it with gramineous crops for more than three years. This reduces soil-borne diseases of ginger, avoids adverse phenomena such as mottled skin, and ensures planting benefits.
2. Soil That Is Too Acidic
Soil is the main cause of mottled skin in ginger. For example, if the soil is too acidic, then it will inhibit ginger's absorption of calcium and boron. This affects the growth of the aboveground part of the ginger plant, reduces the disease resistance of ginger, and thus causes mottled skin. Therefore, we should pay attention to regularly checking the pH of the soil and maintain a suitable pH value; the soil must never be too acidic. If the soil becomes acidified, then substances such as quicklime should be used in time to neutralize it. Then appropriately increase the application of phosphate and potassium fertilizers to improve the disease resistance of ginger plants and reduce the occurrence of adverse phenomena.
3. Soil Compaction
In addition to soil that is too acidic causing mottled skin in ginger, soil compaction is also one of the "chief culprits" causing mottled skin in ginger. The main edible part of ginger is the tuberous root, so the growth of the tuberous root is very important. When planting ginger, we should maintain a good soil environment. If the soil is compacted or too sticky, then it will affect the respiration of ginger roots as well as nutrient absorption. This causes ginger to be unable to grow normally and to develop many phenomena such as mottled skin. Therefore, when planting, we should pay attention to doing good cultivation work, water reasonably, and not use flood irrigation, which can cause soil compaction. After rain, drain water in time to break up soil compaction.
4. Low-Lying Terrain
Low-lying terrain is actually similar in cause to soil compaction. Because in low-lying places, the soil is prone to water accumulation, and if water is not drained in time, then it will also affect the respiration of ginger roots. Then, combined with high humidity, poor permeability and other reasons, mottled skin is very likely to occur. So before planting, we should try to choose a place with flat terrain and good drainage and irrigation capacity for planting, and drain water in time on rainy days to avoid water accumulation. Then we should also do a good job of fertilizing, mainly with compound fertilizer. In addition, trace elements should also be supplemented to ensure that ginger growth has sufficient nutrients.
The above is a brief introduction to what causes mottled skin on ginger. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
