Cucumber "high temperature melon" should have degree
The concept of "high-temperature melon cultivation" involves maintaining a high concentration of carbon dioxide inside the greenhouse, which enhances the plant's photosynthetic efficiency. As the temperature rises, the plants are able to absorb more nutrients, which is beneficial for the growth of melon strips. During the period when cucumber pods are forming, slightly increasing the temperature in the shed can be advantageous for their development. However, it's important to note that excessively high temperatures can have negative effects on the plants.
When the greenhouse temperature reaches 38°C, the photosynthetic activity of the plants is at its peak. But once the temperature exceeds 40°C, the plants start to suffer. Prolonged exposure to such high temperatures can cause wilting and hinder overall growth. Therefore, the idea that "higher is better" when it comes to temperature is not entirely accurate.
In practice, the optimal temperature for the greenhouse should be maintained around 38°C. When the temperature drops to 35°C, ventilation should be initiated to prevent overheating. It’s important not to wait until the temperature becomes too high before ventilating, as this can lead to stress on the plants.
In addition to temperature control, "high-temperature melon cultivation" also requires maintaining high humidity and an adequate supply of carbon dioxide. Proper ventilation must be carried out while ensuring that the temperature remains within the ideal range. If there's a conflict between maintaining heat and providing sufficient ventilation, the use of carbon dioxide gas fertilizer can be an effective solution to support plant growth without compromising the benefits of high-temperature cultivation.
By carefully managing these factors, farmers can optimize conditions for melon development, leading to healthier crops and higher yields.

Water absorbing expansion bag
Denilco water absorbing expansion bag has a wide range of applications and can be used for dam heightening and blockage, water containment and overflow prevention, engineering interception, blockage of hidden ditches and holes, reinforcement of flood control dams at any time, temporary flood control works such as urban waterproof sub embankments and block waterproof walls in flood control and emergency rescue. Before absorbing water, it weighs only 275 grams, and after 2-3 minutes of absorbing water, it can reach 20 kilograms. During emergency rescue, it can replace the soil source and quickly construct rescue projects to reduce losses caused by the lack of soil source on the rescue site and inability to rescue in a timely manner.
