What is the purpose of laying reflective film in apple orchards?
Apple is a very popular fruit in China, and it is grown on a very large area in the country. When growing apples, we need to do a good job of management, especially in the late stage of apple ripening, when management must be strengthened even more. Usually, reflective film is laid along the tree rows to ensure fruit yield and quality. So what exactly is the purpose of laying reflective film in apple orchards? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Improving light conditions
After apples enter the late ripening stage, laying reflective film in the orchard can effectively improve the orchard, especially the light conditions in the inner canopy. It ensures that the fruit on the lower part of the tree and inside the canopy can color evenly, increasing the amount of fully red fruit in the orchard and the commercial value of the fruit. Reasonably laying reflective film is also key to ensuring apple yield and quality. Professional data surveys have shown that when reflective film is laid in an apple orchard, fruit that previously had a coloring rate of about 45% can be increased to 90% or even higher.
2. Regulating soil temperature
In high-temperature seasons such as summer, laying reflective film in an apple orchard can also lower the soil temperature. And in low-temperature seasons such as winter, it also has a warming and insulating effect, ensuring normal growth of the apple tree roots. In addition, after the reflective film is laid, it can also prevent the soil from being impacted by rainwater, avoid soil hardening after rain, improve soil permeability, and promote the formation of soil aggregate structure. Moreover, soil covered with reflective film has significantly stronger water-holding capacity, and the soil moisture evaporation rate is also greatly reduced.
3. Improving fruit quality
In apple orchards where reflective film has been laid, not only can the appearance of the apples be greatly changed, but their internal quality can also be greatly improved. For example, the sugar content and single-fruit weight of the fruit are much higher than in apple orchards where reflective film has not been laid. Therefore, in the late stage of apple tree fruiting, reflective film must be laid appropriately. Using the reflection of the film can not only increase the yield of the apple orchard, but also enhance the quality of the apple fruit in every aspect. Planting benefits can also be greatly improved as a result.
The above is a brief introduction to the role of laying reflective film in apple orchards. From the above, we can see that laying reflective film in apple orchards has many effects, and the benefits for apple growth are also very good. Therefore, when planting, everyone must pay attention to laying the reflective film properly. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
