What kind of environmental conditions does konjac need to grow
Konjac is a perennial herbaceous plant of the Araceae family, and it has a cultivation and food history of nearly two thousand years in China. Konjac has extremely high nutritional value, and also has various effects such as lowering blood lipids, nourishing the skin and dispersing toxins, and stimulating the appetite and relieving constipation, making it a very green food. At present, China's konjac planting area is also relatively large, but it cannot be planted just anywhere, because konjac growth has certain environmental requirements. Below, the editor will introduce the environmental requirements for konjac growth!
1. Temperature
Temperature is an important factor ensuring the growth and development of konjac. It is relatively suitable for growing in a warm environment, and during its growth the optimal temperature should be maintained at around 20°C. The annual average temperature should also be maintained at around 15°C. If the temperature is below 12°C, it will inhibit the growth of konjac roots. During tuber expansion, the temperature range should be controlled at around 22-24°C. During the dormant period of konjac, the minimum temperature must not be lower than minus 5°C, otherwise frost damage is very likely to occur. Therefore, when planting, the temperature must be kept well to ensure it stays within the suitable growth range for konjac.
2. Light
Although konjac is a tropical organism, it has little demand for light and has strong shade tolerance. Moreover, direct sunlight is not conducive to konjac growth, as its requirements for light intensity are weak and the duration is short. Therefore, when planting, we should pay attention to controlling light and do a good job of shading. The light intensity requirement for the aboveground part of the konjac plant must not exceed 2/3 of sunlight, while the roots only need dim light for growth. If the light is unsuitable, it will have a great impact on konjac growth, so direct sunlight on konjac must be prevented.
3. Moisture
Konjac has relatively high water requirements and likes to grow in soil with high water content, rich humus, and good drainage and irrigation. Although konjac can emerge normally relying on the water stored in the tuber, if the soil water content is insufficient, it is very unfavorable for the growth of konjac seedlings and tuber expansion. The soil water content should be maintained at around 77% to ensure normal konjac growth. However, it must not be too wet either. If it is too wet, it will reduce soil permeability and also inhibit the growth of roots and corms. Therefore, when there is too much water, attention should be paid to drainage to prevent pests and diseases, which can cause rot of the corms and roots and reduce planting benefits.
4. Soil
Konjac has relatively strong growth ability and can grow normally in various soils and adapt quickly. However, if manual planting is intended to increase yield and quality, soil with deep layers, high looseness, strong permeability, and good drainage and irrigation should still be selected, so as to better ensure konjac growth, effectively increase konjac yield, and enhance quality. In addition, konjac is suitable for growing in neutral to slightly acidic soil, so we should also keep the soil pH at around 7 to promote konjac growth.
The above is a brief introduction to the environmental condition requirements for konjac growth. Konjac growth has relatively many environmental requirements. Therefore, everyone should not plant blindly and should pay attention to doing preparatory work well to ensure a good growth environment. That is all for today's introduction.
