What are the conditions for growing konjac? A detailed explanation of the latest growing requirements
Some time ago, quite a few people consulted the editor with many questions about growing konjac, so do you really understand konjac? In fact, konjac itself is a toxic substance and can only be eaten after the toxins are removed through processing, otherwise poisoning will occur. So today we are mainly going to learn about several essential conditions for growing konjac. Let's take a look below at what they actually are.
1. Temperature
For konjac to grow normally, the temperature must meet the right conditions. If the temperature is too high or too low, it will affect the growth of konjac. Generally, it is best if the temperature can be between 15 and 25 degrees, which means the average annual temperature should reach around 14 to 16 degrees. When the temperature is below 12 degrees, the konjac in the field will lodge, but it can still tolerate a certain amount of low temperature and will only be killed by frost at around minus 8 degrees. When the temperature is above 35 degrees, it will stop growing. If you want to increase the yield of konjac, then during the growth of the konjac tubers, it is best to keep the temperature between 20 and 25 degrees.
2. Light
Konjac is suitable for growing in tropical and subtropical regions, but this does not mean that it has a very high demand for light, so we still need to properly regulate light intensity. This is also why many people use intercropping when growing konjac, because this can provide a certain shading effect. Konjac is actually a plant that is very afraid of direct light, so when growing it, we should preferably set up a shade shed, or use intercropping, and keep the light at about one third of normal light.
3. Humidity
The humidity of the planting site must also be reasonable. While keeping the field soil moist, you must also be careful to avoid water accumulation in the field or excessive humidity. Generally, the soil humidity of the planting site is best at around 55 to 60 percent, while the humidity in the air should be relatively higher, preferably around 60 to 70 percent. Under these conditions, konjac can grow normally. In other words, the annual rainfall at the planting site only needs to be around 1,000 mm.
4. pH
The growth of konjac actually has no requirements for pH, but if you want konjac to grow well, then we need to adjust the pH of the soil. It is best to keep the pH between 6.5 and 7.5, but it can also grow normally when the pH is between 5.5 and 6.5, as well as between 7.5 and 8. In other words, the pH for planting must not be lower than 5.5, and at the same time must not be higher than 8, otherwise it cannot grow.
These are basically the essential conditions for growing konjac. Of course, konjac growing techniques are also one of its essential conditions, so when growing it, we still need to continuously improve our professional level.
