Requirements of environmental conditions for the growth of konjac

Amorphophallus is a perennial herb of Araceae, which has been cultivated and eaten in China for nearly 2000 years. Konjac has a very high nutritional value, and it also has various effects such as reducing blood lipids, nourishing beauty and dispersing poison, appetizer and laxative, so it is a kind of very green food. At present, the planting area of konjac in China is also relatively large, but it can not be planted everywhere, because the growth of konjac has certain requirements on the environment. The following editor will introduce the growth environment requirements of Amorphophallus.

1. Temperature

Temperature is an important factor to ensure the growth and development of konjac, it is more suitable to grow in a warm environment, and the optimum temperature should be kept at about 20 degrees. The average annual temperature should also be kept at about 15 degrees. If the temperature is lower than 12 degrees, it will inhibit the growth of the root of konjac. When the tuber expands, the temperature range is controlled at about 22-24 degrees. During the dormant period of konjac, the lowest temperature should not be lower than 5 degrees below zero, otherwise it is very easy to produce frost damage. Therefore, when planting, we must maintain a good temperature to ensure that the temperature is within the suitable growth range of konjac.

2. Lighting

Although konjac is a tropical creature, it has little demand for light and has strong shade tolerance. And direct exposure to the sun is not conducive to the growth of konjac, the requirement of light intensity is weak, and the time is short. Therefore, when we plant, we should pay attention to the control of light and do a good job of shading. The light intensity of the aboveground part of the konjac plant should not be higher than 2 beat 3 sunlight, and the root should grow dark light. If the light is not comfortable, it will have a great impact on the growth of konjac, so we must prevent the sun from shining directly on konjac.

3. Moisture

Konjac has a high demand for water and likes to grow in soils with high water content, rich humus and good drainage and irrigation. Although konjac can emerge normally with water stored in a baked tuber, it is very disadvantageous to the growth of konjac seedlings and tuber expansion if the soil water content is insufficient, and the soil water content should be kept at about 77% to ensure the normal growth of konjac. However, do not be too wet, if too wet, it will reduce the permeability of the soil and inhibit the growth of roots and bulbs. Therefore, when there is too much water, we should pay attention to drainage to prevent diseases and insect pests, lead to corm root rot and reduce planting efficiency.

4. Soil

The growth ability of konjac is relatively strong, can grow normally in all kinds of soil, can adapt quickly. However, if artificial planting wants to improve the yield and quality, it is necessary to choose the soil with deep soil layer, high softness, strong permeability and good drainage and irrigation, so as to better ensure the growth of konjac. Effectively improve the yield and quality of konjac, and konjac is suitable to grow in neutral slightly acidic soil, so we also need to keep the soil PH value at about 7 to promote the growth of konjac.

The above is a brief introduction of the environmental conditions for the growth of konjac, and the growth of konjac has more requirements for the environment. Therefore, we should not plant blindly, we should pay attention to the preparatory work to ensure a good growth environment. That's all for today's introduction. This article is for reference only.
