Field management of sweet potato

Sweet potato is called sweet potato in many places, and it is cultivated almost everywhere in our country. The nutrients of sweet potato are more comprehensive, and the planting is relatively simple, and the yield is also higher. But this is also based on the correct management, the field management of sweet potato is very important, and it is also one of the planting work to ensure high yield. So how to manage the sweet potato in the field? The following editor has brought the field management method of sweet potato, let's have a look!

1. Ploughing and weeding

The main edible part of sweet potato is underground tuber, so ploughing and weeding is the primary management work. Before the seedlings grow to about 8 centimeters, the vines are not covered with the ground to do the first ploughing and weeding work. Pay attention to the depth when ploughing, should not be too deep, because the root of sweet potato is shallow, if it is too deep, it is easy to cause root damage. And it can also prevent the fleshy root from being exposed to the outside, which affects the growth of tuber and reduces the quality. Cooperate with weeding in mid-tillage to prevent weeds from occupying the ground growth space of sweet potato, snatching the growth nutrition and leading to the decrease of yield.

2. Water and fertilizer management

In the seedling stage is the most critical time for the growth of sweet potato, but also 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 in this period. Topdressing is carried out together when loosening the soil, and each time the soil is loosened, topdressing is carried out to improve soil fertility, prevent malnutrition of sweet potato, and promote the growth of sweet potato. Heavy fertilization should be applied when the sweet potato reaches the expansion period. In case of high temperature and drought in summer, water should be watered in time, but the moisture should not be too much, and drainage management should be done in rainy weather. If there is too much water, it is easy to cause discoloration of sweet potatoes, cause diseases and insect pests, lead to rot and so on, which have a great impact on the yield and quality.

3. Management of expansion period

The expansion period is a key period in the growth process of sweet potato, which usually reaches the expansion period about 3 months after planting. During this period of high temperature and humidity, the growth ability of sweet potato is very strong, and the leaf area is large, so the management in this period is very important. First of all, we should control the growth of sweet potato stems and leaves, when the growth rate is fast, avoid turning the vine, properly spraying foliar fertilizer is very beneficial to the development of tubers, but also can increase the yield of sweet potato. If you encounter drought during the expansion period, you should water it in time, but do not flood it.

4. Harvest and retain species

The growth cycle of sweet potato is not very long, the period from sowing to harvest is about half a year, and the harvest time varies with different planting areas and varieties. For example, the varieties of middle and late maturity should be harvested in time before the beginning of winter, because this variety has thin skin and poor cold resistance. Secondly, we can also according to the direction of consumption, if it is raw food, then should be early harvest, early harvest of sweet potato meat full and juicy, taste good, but not conducive to storage. Therefore, there is no specific harvest time, everyone in the harvest should be based on the above aspects of comprehensive consideration.

The above is a brief introduction to the field management of sweet potato. Planting sweet potato has a relatively wide area in our country, but there are also many people who fail to grow it. Most of the reasons are caused by not doing a good job in field management, so we must strengthen our own planting management skills.
