How much is the price of sweet potato per jin in 2020? What are the techniques of fertilization in order to produce high yield?

Sweet potato, also known as sweet potato, etc., is a widely planted food crop with strong adaptability to the environment. In addition to being used as a staple food, sweet potatoes can also be used as raw materials for food processing, alcohol, manufacturing industries, and are also very high-quality feeds. How much is the price of sweet potatoes in 2020? What techniques do you pay attention to in order to produce high yields?

How much is the price of sweet potatoes in 2020?

In January 2020, the price of sweet potato has a steady upward trend. The price is about 1-3 yuan per catty. The price will be affected by many factors. Such as varieties, quality, specifications, output, market conditions, etc.

Second, sweet potato fertilization pay attention to what skills can be high yield?

1. Look at the soil

Sandy soil, good ventilation, but poor performance of fertilizer and water retention, fertilizer efficiency is not lasting, and easy to lose, to increase the application of organic fertilizer to improve the soil, the application of quick-acting fertilizer to a small amount, appropriately increase the number of topdressing. Clay soil, due to poor permeability, fertilizer decomposition slow, but fertility strong, so the number of topdressing should not be too small, can be more appropriate to chase, appropriate reduction of topdressing times.

2. Look at Miao Qing

At the branching and tuber setting stage, the underground root net is formed, the tuber begins to expand, and the absorption fertility is strong. At this time, the leaf area of the tuber increases, and the photosynthetic efficiency increases. It is necessary to apply fertilizer as early as possible to achieve the purpose of strong plants, rapid growth and stable growth. For those growing well, the amount of fertilizer can be reduced. If the seedling or group fertilizer nitrogen application is large, potato fertilizer can only apply potassium fertilizer, potassium sulfate can be applied about 10 kg per mu.

3. Look at the time

Tuber fertilizer is generally applied about 45 days after planting. At this time, the above-ground part has been thrown under the ridge, and the potato pieces have been basically shaped. On one side of the ridge, 1/3 is broken with plough, and then fertilizer is applied. Ridge-breaking fertilization can improve soil aeration and help potato expansion. This fertilization is mainly potassium fertilizer, topdressing potassium fertilizer can make stems and petioles thicker, keep them young and tender, and promote potato expansion.

4. Look at water

An important principle of sweet potato fertilization is to control the amount of nitrogen fertilizer under good moisture conditions to avoid excessive stem and leaf growth. 7-8 In high temperature and drought areas, nitrogen fertilizer should be applied before drought to promote stem and leaf sealing before drought. In years with more autumn rain, the number and frequency of topdressing can be appropriately reduced, and vice versa.

5, sweet potato can not be applied with chlorine fertilizer, it will reduce the starch content of potato pieces, but also make potato pieces resistant to storage.
