What are the key considerations for growing konjac? A full breakdown of the latest points

We may not be very familiar with konjac; almost everything we see is processed konjac products, and the main reason for this is that konjac itself is toxic and can only be eaten after processing. Because konjac has effects such as detoxifying and beautifying the skin, lowering blood pressure and blood lipids, and stimulating the appetite, it has also shifted from being a wild plant to being cultivated artificially. Below are some issues to pay attention to when growing konjac, compiled by the editors of Qinnong.com. Let's take a look.

1. Soil

Konjac is somewhat selective about the soil it is grown in, because it is not suitable for planting in plots with high soil clay content. If suitable soil is not chosen, then the survival rate of konjac will be very low, so when planting, be sure to choose yellow soil or purple soil as well as sandy soil and sandy loam, and the soil pH can be moderate or slightly acidic. Finally, another thing to note is that continuous cropping cannot be carried out, and it also cannot be planted in soil where the previous crop was continuously cropped or where the previous crops were peppers and tobacco.

2. Time

The time for planting konjac is also a relatively important issue, because there are certain differences in temperature and climate across various regions of our country, so when planting we need to clearly understand the climate conditions of the location and then choose a suitable time for planting. Taking the Hunan region as an example, usually the best time to sow konjac is around April each spring for sowing and raising seedlings, usually sprouting in about 25 days, and transplanting must be completed in mid-May, which is beneficial to the growth of konjac.

3. Temperature

Planting temperature is also something we need to pay attention to, and at the same time temperature is also an important factor in judging whether we can sow. The optimal temperature suitable for konjac growth is around 15 degrees. When sowing, we need to test the soil temperature. If the soil temperature can remain stable at around 10 degrees, then we can prepare to sow. Secondly, during the growing process, it is best to regulate the temperature reasonably so that the field temperature can be maintained at around 13 to 18 degrees.

4. Density

Unreasonable planting density will bring many troubles to konjac, such as the impact of pests and diseases, slowed plant growth, and the yield and quality of konjac. Under conditions where the soil conditions and other aspects all meet the standards relatively well, on average about 3,000 plants can be planted per mu, and then the number should be increased or reduced according to the specific conditions of the planting site, such as the fertility of the soil and the light conditions of the planting site. Finally, the number of plants per mu must not exceed 4,000.

5. Fertilizer and Water

One of the biggest differences between growing konjac and growing other crops lies in the management of water application. If conditions allow, apply sufficient base fertilizer as much as possible and do not carry out topdressing. At the beginning of planting, water thoroughly and reduce the number of waterings as much as possible, as this is instead more beneficial to its growth. Secondly, the editor here also wants to add one point, which is that konjac does not need much field management and is a rough-cultivation crop; intensive management is instead not beneficial to its growth.
