In summer, the temperature is high, and the sunlight is extreme. For some vegetables that do not like intense light, it is time to take appropriate shading measures.
Sun shade net can block the strong light and reduce the greenhouse's temperature. It is an excellent choice to prevent heat from entering the greenhouse in high-temperature areas. At present, shading net has become necessary for vegetable farmers.
The primary role of sun shade net is to shade and cool down the temperature. Covering agro shade nets is essential for vegetable plantation in the high-temperature season.
But if you don't choose a suitable shade fabric for your vegetables, it not only causes the excessive growth of crops but also is not good for flowering and fruiting. Therefore, vegetable farmers need to choose sunshade net scientifically and reasonably.
The quality of shade netting has no relation with the color. The color of sunshade net is added in the process of raw material manufacturing. Vegetable farmers should choose different colors of shade cloth according to the habits of the vegetables.
Currently, the colors of shade nets in the market are mainly black and green. Black shade net has a high shading rate and cools down quickly, and it is suitable for short-term coverage that needs fine management in hot summer. Green shade net has a low shading rate and is suitable for light-loving vegetables and long-term coverage.
Different colors of agricultural shade net have different shading effects. Red shade net significantly improves the yield of cucumbers and bell peppers. Blue shade net could help the tomato seedlings grow better. White shade net, with the effect of reflecting and scattering light, increases light flux and prevents crops' excessive growth.
High-quality shade netting is made of 100% virgin high-density polyethylene (HDPE). When producing, color masterbatch, UV stabilizer and anti-oxidant are added to raw materials. The final shade netting has a very bright color and a soft touch. The netting has high strength and is ageing-resistant and corrosion-resistant. It is durable, and the service life can reach 3-5 years.
When choosing a greenhouse shade net, it is necessary to consider whether the heat shrinkage of shade cloth is stable. If the heat shrinkage is not stable, it will cause damage to the bracket and slot or tear to the shading net. If the heat shrinkage cannot be confirmed to be stable or not, please try to use it on a small area first.
In addition, if the heat shrinkage is too large, it will increase the shading rate after a period of use. The shading rate is not the higher, the better. Too high shading rate will make the plants photosynthesize descend and the stems thin and weak.
Sun shade netting is woven in different techniques to achieve different shading rates and meet different requirements. The weaving technology usually contains 1 needle, 2 needles, 3 needles, 6 needles, 9 needles etc. Choosing which weaving of shading nets depends on the kinds of crops and the local market demands.
When purchasing sunshade net, vegetable farmers easily choose too high shading rate. Because they think that the shading rate is higher, the cooling effect is better. However, too high shading rate will weaken too much sunlight, reduce photosynthesis, make stalks thin and crop excessive growth. Finally, the crop yield decreased.
The common shading rate contains 35%, 50%, 70%, 90%, etc. The planting of different crops needs different light intensity. Besides, the light compensation point and light saturation point is also different at the different growth stage of crops. So please be sure to choose the appropriate shading rate according to the requirements of the plant crops.
There are many kinds of shade nets in the markets. When purchasing of shade netting, please choose the suitable shading nets to ensure the best effect of shading and cooling. Please confirm to buy high-quality shade net, not only to avoid unnecessary cost and labor, but also to protect the crops better.
