Want to achieve high yield in cold potato cultivation?

Recently, the editors can always see many street vendors pushing a large cart of cold potatoes on the streets and alleys, and in the season when a large number of cold potatoes are on the market, cold potatoes can be eaten raw or fried, the taste is sweet and crisp Is good. In many places, cold potatoes are also called sweet potatoes, so do you know where to pay attention to in order to achieve high yields? Let's take a brief study together.

Recently, the editors can always see many street vendors pushing a large cart of cold potatoes on the streets and alleys, and in the season when a large number of cold potatoes are on the market, cold potatoes can be eaten raw or fried, the taste is sweet and crisp Is good. In many places, cold potatoes are also called sweet potatoes, so do you know where to pay attention to in order to achieve high yields? Let's take a brief study together. 1. Water and fertilizer management At the seedling stage, it is the most critical time for the growth of cold potatoes, and it is also a time when the demand for water and fertilizer is relatively large, so it is necessary to do a good job in the management of water and fertilizer during this period. When topdressing, loosen the soil together. Every time the soil is loosened, a top dressing is carried out to improve the fertility of the soil, prevent malnutrition of cold potatoes, and promote the growth of cold potatoes. Re-fertilization should be applied when it reaches the expansion stage of cold potatoes. When it encounters high temperature and drought in summer, water should be timely, but the water should not be too much, and drainage management should be done in rainy weather. If the accumulated water is too much, it is easy to cause the cold potato to change color, cause diseases and insect pests, and cause rot, etc., which has a relatively large impact on the yield and quality. 2. Cultivation and weeding The main edible parts of cold potatoes are underground tubers, so weeding and weeding of cold potatoes is the primary management task. Before the seedlings grow to about 8 cm, the first cultivating and weeding work is done before the vines have covered the ground. Pay attention to the depth when cultivating, it should not be too deep, because the root of cold potato is shallow, if it is too deep, it will easily cause damage to the root. It can also prevent fleshy roots from being exposed to the outside, which can affect tuber growth and reduce quality. When weeding together with weeding during mid-tillage, weeds are prevented from occupying the ground growth space of cold potatoes, robbing growth nutrients, resulting in a decline in yield. 3. Expansion period management The expansion period is a critical period in the growth process of cold potatoes, and it usually reaches the expansion period about 3 months after planting. During this period of high temperature and high humidity, the cold potato's growth ability is extremely strong, and the leaf area is large, so the management of this period is very important. First of all, we must control the growth of cold potato stems and leaves. When the growth rate is fast, avoid vines and spray foliar fertilizer properly, which is very beneficial to the development of tubers and can also increase the yield of cold potatoes. If you encounter drought during the expansion period, water it in time, but not flood it. 4. Harvesting and retaining seeds The growth cycle of cold potatoes is not very long. It takes about half a year from sowing to harvesting. The harvesting time varies depending on the planting area and variety. For example, mid-to-late varieties should be harvested in time before entering the winter, because this variety has a thin skin and poor cold resistance. Secondly, we can also decide according to the direction of consumption. If it is raw food, it should be harvested early. The early harvested cold potato is full of meat and juicy, and has a good taste, but it is not conducive to storage. Therefore, there is no specific harvest time, and everyone should consider the above aspects when harvesting. In summary, there are some high-yield cultivation points for cold potatoes. If you plant cold potatoes, but don't know how to manage them, you can learn more about these aspects.
