Causes and Control methods of Hollow Potato

Potato, also known as potato, is one of the most common vegetables in our lives. It is the third most important food crop in the world and has a very wide planting area. There is a kind of physiological disease-hollow during planting, which seriously affects the yield and quality of potato and reduces the commercial value of potato. What is the cause of potato hollowness? How to prevent and cure it? Let's have a look with the editor.

1. Hollow symptoms

Potato hollow is generally in the pith of tuber, hollow worm can not see any symptoms outside, can only be found by cutting it, generally occurs on the larger potato tuber. Its hollow is generally star-shaped radial or flat mouth-shaped, there are some holes will be connected together, the hole wall is white or brown, and before the hollow, the internal tissue will be water-immersed or transparent, generally this kind of potato is inedible.

2. Hollow cause

The main reason for the hollow potato is that the tuber expands too fast. during the tuber expansion, due to the improper management of fertilizer and water, the tuber expands too much water, absorbs a large amount of water, and the starch is converted into sugar. resulting in large tubers but less nutrients in the internal tissue, or the internal tissue nutrients are transferred or absorbed, will lead to hollow. In addition, the soil is too dry in the early stage, resulting in a lack of water in the plant, and sudden watering or rainfall in the later stage of fruit growth, while the plant is lack of potassium fertilizer, resulting in nutrients can not be transported in time, resulting in hollow.

3. Prevention and control methods

First of all, we should choose the variety with low hollow rate, and also pay attention to the planting density, reduce the distance between plants, reduce the lack of seedlings rate, reasonable close planting is also one of the measures to prevent hollow. During the expansion of potato tubers, it is necessary to strengthen fertilizer and water management, maintain a uniform supply of water, maintain a suitable soil wettability, and should not be watered for a long time or excessive watering. In the tuber expansion, adding an appropriate amount of potassium fertilizer can accelerate the transport of nutrients, make the plant nutrient area uniform, 1 promote tuber growth and expansion, but also pay attention to soil cultivation.

The above are the causes and control methods of potato hollowness. I hope it can help you. If you want to know more about potato planting, please follow us.
