Greenhouse cooling and sunscreen agent: the "sunscreen" that protects crops
High temperatures in summer pose a significant challenge to crop growth, making greenhouse cooling and sunscreen agents indispensable aids in modern agriculture. This article will provide a detailed introduction to the working principles, selection criteria, and usage tips of greenhouse cooling and sunscreen agents, assisting farmers in safeguarding their "green banks" during the sweltering summer.
1. Greenhouse cooling and sunscreen agent: the "sunscreen" that protects crops
As temperatures rise, the temperature inside greenhouses often reaches levels that crops cannot tolerate. At this point, greenhouse cooling and sunscreen agents come into play. They act like "sunscreen" for crops, effectively blocking ultraviolet rays and excessively strong sunlight, reducing the temperature inside the greenhouse, and maintaining a suitable growth environment.
There is a wide range of greenhouse cooling and sunscreen agents available on the market, ranging from simple sprays to complex coating materials, each with its own unique features. When making a choice, it is important to consider the durability, environmental friendliness, and cost-effectiveness of the product, ensuring that it meets the cooling needs without negatively affecting crops.
II. Greenhouse film cooling and shading agent: a transparent master of cooling
The greenhouse film cooling and shading agent is a special coating that can be sprayed onto plastic film, forming a transparent protective layer. It can not only reduce direct sunlight but also ensure light transmission, allowing plants to receive necessary illumination. This product is particularly suitable for greenhouses that require high light transmittance.
When using greenhouse film cooling and shading agents, it is important to pay attention to their weather resistance and anti-aging capabilities, especially in areas with frequent rainfall, where selecting products with strong rainwater resistance is particularly crucial. In addition, regularly checking the coating status and timely reapplication are also key to ensuring the cooling effect.
III. How to choose the most suitable greenhouse cooling agent?
When selecting a greenhouse cooling agent, the first thing to consider is the product's scope of application and its effectiveness persistence. For example, in areas that frequently experience heavy rain, a cooling agent with strong rain resistance will be the best choice; whereas for greenhouses that need to maintain a lower temperature for a long time, a product with efficient cooling function should be selected.
Secondly, the environmental friendliness and safety of the product cannot be ignored. A high-quality cooling agent should not only effectively lower the temperature in the short term but also possess good biodegradability to avoid polluting soil and water sources.
IV. Usage Tips and Precautions
Proper use of greenhouse cooling and sunscreen agents can not only enhance their effectiveness but also extend their lifespan. For instance, before applying the cooling agent, it is essential to clean the surface of the greenhouse film to eliminate dust and stains, ensuring even distribution of the coating.
In addition, it is also crucial to adjust the frequency of using cooling agents according to seasonal changes. During the high temperature period in summer, the number of spraying may need to be increased, while it can be appropriately reduced when the temperature drops in autumn.
In summary, greenhouse cooling and sunscreen agents are indispensable tools in modern agriculture. Proper selection and use of these agents can effectively protect crops from high temperature damage, ensuring a bountiful harvest.
