A Detailed Guide to the Latest Mid-to-Late Stage Management Techniques for Konjac

Konjac is a rather special vegetable, belonging to the corm-type vegetables. It is rich in nutrients and is also very popular with many people. Its taste is soft, glutinous and refreshing, and it also has relatively large market demand, so there are quite a lot of people growing konjac nowadays. When growing konjac, we need to do a good job of management. Especially in the mid-to-late stage, so how should konjac be managed in the mid-to-late stage? Today the editor brings you the mid-to-late stage management techniques for konjac, so let's take a look below!

1. Water management

Konjac relatively prefers to grow in a humid environment, so a relatively moist soil environment should be maintained. During the corm swelling period of konjac, its water content should be kept at around 75%. The water content must not be too high; if the soil humidity is too high, then the soil permeability will be too low, which is very unfavorable to the growth of the corm. But it must not be too low either; if the soil water content is lower than 60%, then it will affect the swelling of the corm. Therefore, the watering method should mainly be irrigation, and it is best to be able to use sprinkler irrigation.

If heavy rain is encountered in the mid-to-late stage, then we should also pay attention to doing a good job of drainage and waterlogging prevention, to avoid water accumulation causing waterlogging and dead seedlings. Generally, September to October each year is the late growth stage of konjac, and at this time we should control the water well. Keep the soil water content at around 60% to promote the accumulation of nutrients in the underground corm. If there is too much water, then it will affect the formation of dry matter. This will lead to a decline in konjac yield and quality. Only by controlling water well can high yield and high quality of konjac be ensured.

2. Fertilization management

For konjac, August to September is the period when it absorbs more fertilizer. At this time, nitrogen fertilizer is mainly used, and its amount is about 60% of the entire growth period of konjac. Among these, potassium is even more important, and konjac absorbs more of it, generally about twice the amount of nitrogen absorbed. In June to July, konjac is in its corm-changing period, and at this time we should do a good job of the first topdressing. The second should be carried out during the tuber swelling period, and then foliar fertilizer should also be appropriately sprayed to enhance the disease resistance of konjac.

3. Pest and disease control

Then in the mid-to-late stage of konjac, we should also focus on doing a good job of pest and disease control for konjac. Because in the mid-to-late stage, it is a peak period for konjac disease occurrence, among which soft rot and southern blight are especially common. We should mainly focus on prevention, strengthen management, control water and fertilizer well, and not apply too much, to prevent waterlogging damage and fertilizer damage. This can trigger konjac pests and diseases, and then we should also frequently observe the growth of konjac. If abnormalities are found, then they should be dealt with in time, identify the cause and then take corresponding measures, to avoid worsening of the condition.

The above is a brief introduction to the mid-to-late stage management techniques for konjac. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
