How to carry out field management of purple sweet potato? Detailed explanation of the technical key points

The field management of purple sweet potato

1. Seedling management

Purple sweet potato is generally planted by cuttings. Usually, the seedlings must be watered immediately after transplanting. The purpose of watering is to stabilize the growth of the seedlings and increase the growth rate. Then, about one week after planting, check the seedlings in time to observe whether there are weak seedlings or dead seedlings. If there are, remove the useless seedlings in time and then replant to ensure the yield of the sweet potato field.

2. Water management

As just mentioned, the planting water should be watered in time after planting. In fact, this is only the first step in water management. After watering, the amount of water should be properly controlled, because excessive watering at the seedling stage can easily cause excessive vegetative growth of purple sweet potato later and promote root development. When purple sweet potato grows to the bulking stage, the soil surface must always be kept moist. The water content must not be lower than 70%, to prevent alternating wet and dry conditions from causing soil compaction and affecting tuber bulking.

3. Fertilizer management

When planting, we should not only apply sufficient base fertilizer, but also properly topdress according to the nutritional needs of purple sweet potato. In the early stage of planting, follow the principle of applying small amounts more frequently and advance the fertilization time. In the middle stage, apply fertilizer flexibly according to soil fertility and the growth of purple sweet potato. In the later stage, apply fertilizer to stabilize the seedlings, promote tuber bulking, and improve yield and quality. When fertilizing, reasonably control the nutrient ratio of the fertilizer. No nutrient should be lacking, to prevent nutrient deficiency from hindering purple sweet potato.

4. Weeding and lifting vines

Weeding and lifting vines is relatively important for the growth of purple sweet potato, because if this work is not done well, it will cause malnutrition in purple sweet potato, hinder nutrient absorption, and weaken growth. Especially when purple sweet potato grows to the middle stage, we should properly remove weeds in the field and combine this with lifting the vines, to prevent purple sweet potato from forming deformed tubers and ensure sufficient yield.

5. Timely harvesting

Harvest time is also very important, because when harvesting we must not only consider the growth progress of purple sweet potato, but also observe market demand and market prices. However, purple sweet potato should not be left in the soil for a long time after maturing, as this can easily lead to rotten tubers and various pests and diseases. After harvesting, do not rush to market it; do a good job of storage. If management during storage is not done well, various pests and diseases can also easily occur.

The above is a brief introduction to the field management methods of purple sweet potato. The way purple sweet potato is planted is not much different from that of sweet potato, but managing it is not as simple as imagined. Therefore, when planting, everyone must learn more management techniques in order to better increase yield and maximize their own economic benefits. That is all for today's introduction.
