Many areas of the potato are planted. In the daily planting and production process, there are often problems such as potato block rot, which is very troublesome for potato farmers. Four factors will cause it to rot. Do you know which four are the two? How do you separate them? Let's take a look at it.
Four causes of potato rot
First, planting factors
1. The area of ​​the cut is too large, and the seedlings after planting are too fragile, and the final result will be decay.
2, the cut is not up to standard, there is no sprout on the potato block, it can not germinate after planting, and finally it will lead to decay.
3, the seedlings are not properly preserved, the environment is too humid, and too much moisture during planting causes the potato pieces to rot.
Second, environmental factors
1. The soil is too moist. It is necessary to know that the potato is not suitable for the soil that is too moist. Otherwise, the potato chips in the ground will absorb too much water and break the epidermis, leading to decay.
2. If the temperature is too high, if the temperature is too high, the environment will be sultry, which will cause the potato surface to breed microorganisms or even ferment, which will cause the potato pieces to rot.
Third, the disease factors
Disease is one of the main factors leading to the decay of potato. The potato tubers grow in the ground for a long time and are easily damaged by underground pests. In addition, diseases such as ring rot appear from the top of potato chips. Directly corrodes the epidermis into the interior.
Fourth, management factors
1. Avoid continuous cropping. If the potato is planted for a long time in the same piece of land, the original body will be accumulated. At this time, it will be rotted easily.
2, after the disease occurs in the potato, the post-processing work is not comprehensive, and it will lead to secondary infection in the planting area.
3. Before the potato is planted, if the weed compost is used, the pathogen will remain in the soil and the potato will be harmed in the later stage.
From the above factors that cause the potato to rot, we can see that when planting, we can do the drainage work in advance, and also burn some wood ash after cutting, the wood ash covers the sliced ​​potato chips, which can effectively improve the species. The survival rate of seedlings, this soil method has been used by many farmers, and is the experience accumulated over hundreds of years.
