Management techniques in the middle and later stage of Amorphophallus

Konjac is a kind of special vegetable, which belongs to a kind of bulb vegetable. It is rich in nutrients and is welcomed by many people. The taste is soft, waxy and refreshing, and there is also a large market demand, so there are still many people planting konjac. When planting konjac, we need to do a good job of management. Especially in the middle and later period, how to manage the konjac in the middle and later period? Today, the editor has brought you the management technology in the middle and later period of Konjac. Let's take a look at it.

1. Water management

Amorphophallus prefers to grow in a moist environment, so it is necessary to maintain a moist soil environment. During the expansion period of konjac corm, its water content should be kept at about 75%. The water content should not be too large, if the soil moisture is too high, then it will lead to low soil permeability, which is very disadvantageous to the growth of the corm. But it should not be too low, if the soil water content is less than 60%, then it will affect the expansion of the corm. Therefore, the watering method should be based on irrigation, and it is best to carry out sprinkler irrigation.

If we encounter heavy rain in the middle and later stages, we should also pay attention to the work of drainage and waterlogging prevention to avoid causing stagnant water to cause waterlogging and death of seedlings. Generally speaking, September to October every year is the late growth stage of konjac, at this time we have to control the moisture. Keep the soil water content at about 60% to promote the accumulation of nutrients in underground corms. If there is too much water, it will affect the formation of dry matter. As a result, the yield and quality of konjac decreased. Only by controlling moisture well can the high yield and high quality of konjac be guaranteed.

2. Fertilization management

Amorphophallus konjac absorbs more fertilizer from August to September. At this time, it is mainly nitrogen fertilizer, and its dosage is about 60% of the whole growth period of konjac. Among them, potassium is more important, and konjac absorbs more, generally about twice as much as nitrogen. From June to July, we are in the changing period of Konjac, when we should do a good job of topdressing for the first time. The second time should be carried out during the tuber expansion period, and then appropriate foliar fertilizer should be sprayed to enhance the disease resistance of konjac.

3. Pest control

Then in the middle and later stage of Konjac, we should also focus on the prevention and control of diseases and insect pests of Amorphophallus. Because in the middle and later period, it is a peak of konjac disease, in which soft rot and white silk disease are particularly common. We mainly focus on prevention, strengthen management, control water and fertilizer, not too much, to prevent the emergence of waterlogging and fertilizer damage. Thus cause konjac diseases and insect pests, and then often observe the growth of konjac. If abnormal is found, then we should deal with it in time, find out the cause and then take corresponding measures to avoid aggravation of the disease.

The above is a brief introduction of the management technology in the middle and later stage of Konjac. That's all for today's introduction. This article is for reference only. I hope it can help you all.
