High light intensity in summer is a taboo for summer vegetables. Regardless of solanaceous vegetables or melon vegetables, they exceed physiological tolerance and can cause many physiological diseases, resulting in reduced yield and deteriorated quality. Therefore, the sunshade net has been widely promoted in summer vegetable cultivation, and has received good cooling effect. However, sometimes the high temperature inside the greenhouse cannot be lowered, and the built-in sunshade net is often used to restrict the farm due to restrictions on the shed. Operation, there are disadvantages such as high cost and inconvenient installation. Now it is very simple and easy for the vegetable growers to introduce an alternative to the shade net.
Use sandy soil or sandy loam, add water and evenly diluted mud, and use a tool (or hold it in your hands) to spray it evenly on the roof of the house on sunny mornings or in the afternoon (splash area is the same as the area covered by the original shade net). The sunshade effect of this method is the same as that of the sunshade net, but it has no cost and is easy to operate. The disadvantage is that it must be splashed once again after being washed by heavy rain.
