Why should the greenhouse use the shading net in the greenhouse or outside the greenhouse or outside?

1. Why do greenhouse greenhouses use Shading nets

1. Over -Shading effect

The Shading net reduces the intensity of the light in the greenhouse. The larger the density specifications, the better the Shading. The same specifications are better than silver -gray Shading.

2. Cooling effect

The temperature in the shed decreased due to the coverage of the shade net, and the cooling of the surface and soil farming layer was ideal. At 10 am -at 2 am, the temperature of the upper part of the greenhouse was 37-40 C, and the temperature around the surface plants was 22-26 C. The soil was soil.The temperature is between 18 and 22 C, which is suitable for crop growth.

3. Baoyao anti -strict rain

The evaporation in the shed decreases, the soil water content is higher than the dew, and the surface soil is moist.Because the Shading net can break down the rainstorm into drizzle, the free leaves are injured by heavy rain, and the soil is not easy to end. The gap is large and the ventilation is good.

Based on the above effect of the Shading net, many greenhouse vegetable growers generally choose to cover the Shading net in the greenhouse plastic film. In this case, the Shading effect is better, which is more beneficial for crop growth.

Second, the Shading net is placed inside the greenhouse or outside

1. When the Shading net is placed outside the greenhouse, because it directly blocks the sunlight outside the greenhouse, it makes its light calories not transmitted to the inside of the greenhouse, thereby achieving a certain cooling role while covering the light, thereby playing a certain cooling role, therebyIt is also more conducive to avoiding the radiation of strong sunlight, thereby reducing the impact of high temperature on vegetable growth.

2. When the Shading net is placed inside the greenhouse, the Solar light can still enter the interior through the greenhouse film, so that the heat will also be brought in, so this method of use will not change the internal temperature, but it can cover the Solar ray of the sunlight.The impact on vegetables is suitable for vegetables that require temperature but also want to avoid ultraviolet irradiation.

Only by mastering the correct usage method and clearing the different functions produced by different use methods can we play the role of the shade net to the point, which is more conducive to the good and rapid growth of vegetables, thereby bringing a considerable economy to the growers to bring a considerable economybenefit.
