What are the conditions for growing konjac? A detailed explanation of the environmental requirements
Some time ago, many people asked our editor a lot of 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. Today we are mainly going to look at the several essential conditions for growing konjac. Let's see what they are below.
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 to keep it between 15 and 25 degrees, which means the average annual temperature should reach about 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 cold, and will only be killed by freezing 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 it has a large demand for light, so we still need to properly regulate the light intensity. This is also why many people use intercropping when growing konjac, because this can provide a certain amount of shading. Konjac is actually a plant that is very afraid of direct light, so when planting, we should preferably build a shade shed, or use intercropping, to 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 should also be careful to avoid water accumulation in the field or excessive humidity. Generally, the soil humidity of the planting site is best kept at around 55 to 60 percent, while the humidity in the air is relatively higher, preferably around 60 to 70 percent. Only under such conditions can konjac grow normally. In other words, the annual rainfall at the planting site only needs to be around 1,000 millimeters.
4. pH
Konjac's growth actually has no requirements for pH, but if you want konjac to grow well, then we need to adjust the soil pH. 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 planting, we still need to continuously improve our professional level.
