Although potatoes are easy to grow and grow, we still need to do some necessary work in order to obtain high potato yield. Here is a key job that can maximize production.
When we plant potatoes, sometimes we plant the whole potato, and sometimes we cut the potato seeds into two or four pieces. No matter which way we plant potatoes, there is a great possibility that a potato will grow many seedlings. For example, a complete potato seed generally grows about five potato seedlings, which will lead to too dense potato seedlings, affect the photosynthesis of potato seedlings, and provide a good hiding place for pests. Not only that, they will also compete with each other.
Therefore, when the potato seedlings grow to the height of 10 cm, we need to carry out a necessary management of the potato seedlings, that is, thinning the seedlings, cutting off the weak potato seedlings in a bunch of potato seedlings with scissors, leaving only two potato seedlings, and it is best not to stick together, but to have some spacing.
When we cut potato seedlings, remember not to pinch them by hand or pull them out by hand, but really cut them with scissors, and they are embedded in the soil to cut off weak potato seedlings, so that the wound can go deep into the soil and avoid diseases.
After all the potato seedlings have been pruned, the next step is to take preventive measures. The most common method is to sprinkle plant ash and those dry plant ash. Sprinkle a layer of plant ash on the roots of the cut potato seedlings. If the wound is exposed to the soil surface and stained with plant ash, it can heal quickly and effectively avoid the invasion of various germs. If the wound is buried in the soil, the alkali in plant ash will penetrate into the soil after being wetted by water, and various diseases can also be prevented.
After applying plant ash, it can not only sterilize and prevent diseases, but also supplement a lot of potassium nutrients, thus promoting the growth of potato seedlings; However, before sowing plant ash, it is suggested to loosen the soil first, because the soil is loose, and plant ash scattered on it is more likely to float into the soil.
After sowing plant ash in the roots of potato seedlings, it is necessary to do the last job well, that is, cultivate the soil, hook the soil on both sides of the ridge manually with hoes, and bury the roots of potato seedlings again, so that the plant ash above will naturally cover under the soil, which will not only prevent plant ash from being washed away by water or blown away by the wind, but also improve the utilization rate of plant ash.
After the potatoes grow to more than ten centimeters, thinning, spreading plant ash and ridging are an integral work, which is the key work in potato planting and can increase the yield of potatoes. Everyone should pay attention to it.
