Field Management of Purple Potato

Purple potato cultivation has gradually become a major food planting project in China, and purple potato is also a favorite food. The technology of planting purple potato is also more mature, but people do not know how to manage it after planting. The management of purple potato is very important, so how should we manage it after planting? Today, the editor brings you the field management method of purple potato. Let's take a look at it.

1. Seedling management

Purple potato is generally planted by cutting, and the seedlings are usually watered immediately after transplanting. The purpose of watering is to stabilize the growth of seedlings and improve the growth rate. Then the seedlings should be checked in time about a week after planting to see if there is a phenomenon of weak seedlings dying. If so, the useless seedlings should be pulled out in time, and then the seedlings should be replenished to ensure the yield of potato fields.

2. Water management

As I just said, planting water should be poured in time after planting. 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 in the seedling stage can easily lead to the later growth of purple potato and promote the development of roots. When the purple potato grows to the expansion stage, it is necessary to keep the surface moist at all times. The water content should not be less than 70% to prevent sudden wetness and dryness from causing soil consolidation and affecting the expansion of tubers.

3. Fertilizer management

When we plant, we should not only apply sufficient base fertilizer, but also apply appropriate topdressing according to the nutritional needs of purple potatoes. In the early stage of planting, follow the principle of a small amount of more application, early fertilization time. Flexible fertilization should be applied in the middle stage according to the soil fertility and the growth of purple potato, and stable seedling fertilizer should be applied in the later stage to promote the expansion of tubers and improve the yield and quality. When fertilizing, we should reasonably control the nutrition ratio of fertilizer, and we can not lack any kind of nutrition, so as to prevent the hindrance to purple potato caused by insufficient nutrition.

4. Weeding Titian

Weeding and vine lifting work is more important for the growth of purple potato, because if this work is not done well, it will cause malnutrition, hinder nutrition absorption and weaken the growth of purple potato. Especially when the purple potato grows to the middle stage, we should properly remove the weeds in the field and cooperate with the vine to prevent the purple potato from forming deformed potatoes and ensure adequate yield.

5. Timely harvest

Harvest time is also critical, because when we harvest, we should not only consider the growth progress of purple potatoes, but also observe the market demand and market price. However, purple potatoes should not be allowed to stay in the soil for a long time after ripening, which is prone to rotten fruit and various diseases and insect pests. If you are not in a hurry to appear on the market after harvest, you should do a good job in storage, and if you do not do a good job in management during the storage period, it is also very easy to produce all kinds of diseases and insect pests.

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