In summer, high light intensity can be a major challenge for growing vegetables. Whether it's solanaceous crops like tomatoes and peppers or melon vegetables such as cucumbers and watermelons, excessive sunlight can push them beyond their physiological limits, leading to various physiological disorders. These issues often result in lower yields and poor quality. To combat this, shade nets have become widely used in summer vegetable farming, offering effective cooling. However, there are limitations—sometimes the temperature inside greenhouses remains too high, and the built-in shade nets may not be sufficient. Additionally, these nets can restrict farm operations, come with high costs, and are inconvenient to install.
Now, there’s a simple and cost-effective alternative that farmers can easily adopt. Instead of using traditional shade nets, growers can apply a mixture of sandy soil or sandy loam, mix it with water to create a slurry, and use a tool or even their hands to evenly spray it onto the roof of the greenhouse. This should be done on a sunny morning or in the afternoon, covering the same area as the original shade net. The shading effect achieved through this method is comparable to that of a traditional shade net. What makes it especially appealing is that it's completely free and easy to apply. The only drawback is that the coating needs to be reapplied after heavy rain. Despite this minor inconvenience, it's a practical and efficient solution that many farmers are starting to embrace.
