It is made of brand-new HDPE material, which is drawn and manufactured with fine mesh and can be reused and kept for a long period of time, up to 3-5 years.
The existing color of insect screen is mostly white, but it can also be made in green, black, blue and yellow.
There are many mesh sizes, from 16 to 120 mesh, we often make 32 mesh, 40 mesh and 50 mesh. The larger the mesh number is, the denser the insect screen is. The effect of the larger mesh number on the temperature and humidity in the greenhouse is greater than that of the smaller mesh number.
Insect protection netting features
Insect-proof nets can prevent insect pests
It can control multiple pests, such as green cabbage moth, chard moth, kale moth, twig moth, yellow currant flea beetle, ape leafworm, aphid, etc.
- Generally speaking, 40-60 mesh insect screen can basically play the effect of aphid prevention, but also conducive to ventilation and air exchange.
- Insect screens of 20-30 mesh are used to prevent adult lepidopteran insects such as greenfly and lepidopteran moth.
- Insect netting for fruit trees is generally 40 mesh, 40 Mu insect netting can block outdoor pests such as whiteflies, aphids, moths and red spiders.
- For vegetable production, we use 20 to 32 mesh black insect netting.
According to the characteristics of vegetables to choose the appropriate insect net, shade-tolerant vegetables, the need to strengthen the shading effect to choose black insect net.
Light-loving vegetables should use white insect-proof nets with fewer mesh and larger mesh.
Virus disease damage to vegetables using silver gray net to avoid aphids and disease prevention effect is most prominent.
Under the premise of effectively preventing aphids, the main pest with the smallest shape on vegetables, the smaller the mesh should be, the better, in order to facilitate ventilation.
Insect netting has good light transmission, shading and moisture regulation
The shading rate of 25 mesh white insect screen is 15%-25%, which is lower than shade net and agricultural film. Silver gray insect screen is 37% and gray insect screen is up to 45%. The air humidity in the morning is higher than that in the open field when the net is covered with insect protection, and lower than that in the open field at noon and in the evening.
The relative humidity inside the net is about 5% higher than that in the open field, and nearly 10% higher after watering, which is especially suitable for cultivation in summer and autumn. Seasonal light intensity, strong light will reduce the growth rate of vegetable crop nutrition, and the insect net can play a role in shading and prevent direct light.
Insect-proof nets can regulate the temperature
Experiments have shown that the temperature in a shed covered with insect-proof nets is about 1-2°C higher than that on land.
Insect-proof nets protect against heavy rain and strong winds
After covering the insect-proof net, due to the small mesh and high strength, the rainstorm has become drizzle after the impact of insect-proof net, and the impact is weakened, which is beneficial to the growth of vegetables.
According to the measurement, under 25-mesh insect protection net, the wind speed in the greenhouse is 15%-20% lower than that in the open field. Under 30-mesh insect net, the wind speed is reduced by 20%-25%, thus the insect net has a better role in resisting strong wind.
