Latest Key Technical Points for Field Management of Purple Sweet Potato
Purple sweet potato cultivation has now gradually developed into a relatively major food crop planting project in our country, and purple sweet potato is also a food that everyone quite likes to eat. The technology for growing purple sweet potato is also relatively mature, but after planting, everyone does not quite know how to manage it. The management of purple sweet potato is very important, so how should we manage it after planting? Today, the editor brings you the field management methods for purple sweet potato. Let's take a look below!
1. Seedling management
Purple sweet potato is generally planted by cuttings, and usually after transplanting, the seedlings must be watered immediately. The purpose of watering is to stabilize the growth of the seedlings and increase the growth rate. Then, about a week after planting, check the seedlings in time to observe whether there are weak seedlings or dead seedlings. If there are, promptly pull out the useless seedlings and replant to ensure the yield of the sweet potato field.
2. Water management
⟦NL>As just mentioned, after planting, the planting water should be watered in time. In fact, this is only the first step in water management. After watering, the amount of water should be properly controlled, because excessive watering during the seedling stage can easily cause excessive 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 must not only apply enough base fertilizer, but also apply appropriate topdressing according to the nutritional needs of purple sweet potato. In the early stage of planting, follow the principle of small amounts and frequent applications, and advance the fertilization time. In the middle stage, fertilize flexibly according to soil fertility and the growth of purple sweet potato. In the later stage, apply stable seedling fertilizer to promote tuber bulking and improve yield and quality. When fertilizing, reasonably control the nutrient ratio of the fertilizer. No nutrient can 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 vines, to prevent purple sweet potato from forming deformed tubers and ensure sufficient yield.
5. Timely harvesting
Harvest time is also very critical, 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 fruit 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 the editor's brief introduction to field management methods for purple sweet potato. The way to plant purple sweet potato is not much different from 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 economic benefits. That is all for today's introduction.
