Q:Why should I granulate before injection? What's the advantage of granulation?: The material should be added with color or some additives, and it will not be fully uniform in the injection machine screw after manual mixing, which will lead to problems of color, flower or other material performance. Secondly, the broken material also particles broken and broken sheet (bottle), the particle breakage has little effect on sheet material broken because the density is too low, the injection molding machine in storage screw is easy to slip, the injection molding process is affected. Of course, if the product requirements are not high, as long as the broken material does not affect the injection, you can use the broken material.

Q:Can olive nets be used in olive groves with limited access for machinery?: Yes, olive nets can be used in olive groves with limited access for machinery. Olive nets are typically lightweight and can be manually installed and removed, making them suitable for groves with restricted machinery access. They provide an effective method for harvesting olives by catching the fallen fruits, allowing for easier collection and minimizing damage to the trees and surrounding areas.

Q:How do olive nets prevent olives from being eaten by insects?: Olive nets act as a physical barrier that covers the olive trees, preventing insects from reaching and feeding on the olives.

Q:How do olive nets compare to other harvesting methods?: Olive nets are a highly effective and widely used method for harvesting olives. They offer several advantages compared to other harvesting methods. Firstly, olive nets are cost-effective as they require minimal investment and can be reused for multiple harvest seasons. Secondly, these nets are environmentally friendly, as they minimize damage to the trees and prevent olives from coming into contact with the soil, reducing the risk of contamination. Additionally, olive nets allow for efficient harvesting by collecting a large quantity of olives at once, saving time and labor compared to manual picking. Overall, olive nets provide a practical and efficient solution for olive harvesting, making them a preferred choice among farmers and ensuring a high-quality yield.

Q:Can olive nets be used to diversify income streams in olive farming?: Yes, olive nets can be used to diversify income streams in olive farming. Olive nets not only protect the olives from birds and pests but also facilitate the collection of fallen olives, which can be used for various purposes such as olive oil extraction, table olives, or even value-added products like olive leaf tea or olive-based skincare products. Additionally, farmers can rent out their olive nets to other olive growers, providing an additional source of income. Overall, olive nets can contribute to diversifying income streams in olive farming and maximizing the economic potential of the crop.

Q:How do olive nets prevent damage from fungal infections?: Olive nets prevent damage from fungal infections by creating a physical barrier that prevents fungi spores from directly coming into contact with the olive fruits. This barrier blocks the entry points for fungal pathogens, reducing the chances of infection and subsequent damage to the olives.

Q:How does an olive net affect the sunlight exposure of the olive trees?: An olive net significantly reduces the sunlight exposure of olive trees. The net acts as a shade, blocking a considerable amount of sunlight from reaching the trees' leaves and fruit. This reduction in sunlight exposure can have various impacts on the trees, including inhibiting photosynthesis, affecting fruit ripening, and potentially altering the overall growth and productivity of the olive trees.

Q:How do olive nets affect the quality of the olives?: Olive nets play a crucial role in maintaining the quality of olives by preventing them from falling to the ground and getting damaged. These nets not only safeguard the olives during harvesting but also protect them from direct contact with soil, which can lead to spoilage and contamination. By ensuring that olives remain intact and undamaged, olive nets contribute to preserving their freshness, flavor, and overall quality throughout the harvesting process.

Q:Do olive nets protect olives from birds?: Yes, olive nets are specifically designed to protect olives from birds.

Q:Can olive nets be used in conjunction with pruning activities?: Yes, olive nets can be used in conjunction with pruning activities. Olive nets are commonly used to collect the pruned branches and leaves during olive tree pruning. They help in keeping the pruned material contained and make the clean-up process easier. Additionally, olive nets also prevent the pruned branches from falling onto the ground, reducing the risk of damage to the branches and making it more convenient to gather and dispose of the pruned material.
