Field management of the latest purple potato

Purple potato planting has gradually developed into a relatively major food planting project in China, and purple potato is also a food that everyone likes to eat. The technology of planting purple potato is also relatively mature, but everyone does not know how to manage it after planting. Purple potato management is very important, so how should we manage it after planting? Today, Xiaobian brought you the field management method of purple potato. Let's take a look at it together!

1. Seedling management

Purple potato planting is generally planted by cutting, usually watering seedlings immediately after transplanting, the purpose of watering is to stabilize the growth of seedlings and improve growth speed. Then in a week or so after planting to check seedlings in time to observe whether there are weak seedlings dead phenomenon. If there are useless seedlings to be removed in time, and then make up seedlings to ensure the yield of potato fields.

2, water management

Just said, after planting to timely watering planting water, in fact, this is only the first step in water management. After watering, it is necessary to properly control the amount of watering, because excessive watering at the seedling stage is likely to cause purple potato to flourish in the later stage and promote the development of roots. When purple sweet potato grows to the expansion stage, it is necessary to keep the surface wet at all times. Water content should not be lower than 70%, to prevent moisture and dryness caused by soil hardening, affecting tuber expansion.

3. Fertilizer management

We should not only apply sufficient base fertilizer when planting, but also apply appropriate topdressing according to the nutritional needs of purple potato. In the early planting period, follow the principle of small amount and more fertilizer, and apply fertilizer in advance. According to the fertility of soil and purple potato growth, fertilizer should be applied flexibly in the middle stage, and stable seedling fertilizer should be applied in the later stage to promote tuber expansion and improve yield and quality. When fertilizing, control the nutrient ratio of fertilizer reasonably, and cannot lack any kind of nutrition to prevent insufficient nutrition from hindering purple potato.

4. Weeding and vine lifting

Weeding and vine extraction is important for the growth of purple sweet potato, because if this work is not done well, it will cause malnutrition of purple sweet potato, blocked nutrient absorption and weak growth. Especially when purple potato grows to the middle stage, we should properly remove weeds in the field and cooperate with the vine to prevent purple potato from producing abnormal potatoes and ensure sufficient yield.

5. Timely harvest

Harvest time is also critical, because we harvest time not only to consider the purple potato growth progress, but also to observe the market demand and market price. However, purple sweet potato can not be allowed to stay in the soil for a long time after maturity, easy to appear rotten fruit and various diseases and insect pests. After harvest, do not rush to market to do a good job of storage, storage period is not well managed, then it is easy to appear a variety of pests and diseases.

The above is a brief introduction to the field management method of purple potato in Xiaobian. The way of planting purple potato is similar to sweet potato, but the management is not as simple as imagined. Therefore, everyone must learn more management skills when planting, in order to better improve the yield and maximize their own economic interests.
