Why Cover Shade Cloth For Ginseng Plants?

Ginseng is a shade-loving plant preferring to grow in a cool place. High temperature and high light intensity will lead to poor ginseng growth and even will bring in secondary diseases such as leaf blight, sunburn, and black spots, which will seriously affect ginseng growth.

When the summer comes, the temperature in the greenhouse usually exceeds 35 ℃ at noon. How to reduce greenhouse temperature and light intensity is a great concern for ginseng farmers. 

At present, ginseng farmers mainly use shade cloth to shade and cool. But if some ginseng farmers use it improperly, the shading net not only does not play its role of shading and cooling but also affects the expected yield of ginseng.

How to use shade cloth for ginseng plants

Install shade cloth

To avoid strong spring winds and save work, many ginseng farmers install the shade net first and then cover the ginseng film. Putting the ginseng film on top of the shade nets is incorrect. In summer, it will raise the temperature in the greenhouse and inhibit the growth of ginseng, and even various kinds of dead leaves and nutritional deficiency will appear due to high temperature.

Cover shade cloth

To help ginseng grow, the farmers will make the rainwater fall on the ginseng seedlings when it rains. They remove the plastic film directly but do not install the shade netting. Without shade netting, the intense sunlight can easily burn ginseng leaves. So shading net should be covered after taking off the plastic film.

Reduce the light intensity

The sunlight intensity in summer (10:00-15:00) is often 80,000-120,000 lux, while the light saturation point of ginseng is 30,000-50,000 lux. Strong light will not only burn the leaves and fruits, but also make the leaves enter the light saturation state prematurely, resulting in decreased photosynthetic efficiency. Sun shade cloth can reduce the light intensity effectively to protect ginseng from burning and promote ginseng growth.

Lower the temperature

Generally, when the temperature inside the greenhouse is above 30℃ for a long time, sun shade net should be set. On the one hand, high temperature will cause ginseng growth to be hindered; on the other hand, it will easily cause drought conditions in the greenhouse, which will cause leaf blight and nutrient deficiency symptoms.

During the Ginseng planting, sudden high temperatures may appear after rain. The drastic change in temperature is very harmful to young seedlings. It can cause the sunburn of young seedlings and dry the stems near the ground. Agricultural shade nets can help reduce temperature and increase humidity. Meanwhile, the ginseng seedling is protected from adverse weather and pest invasion.

Conclusion

Shade cloths have a good shading and cooling effect. It is widely used in ginseng planting, which greatly improves the yield and quality of ginseng, increases ginseng survival rates effectively, and makes manual labor a minimum.
