How to spread the reflective film in apple orchard

Apple has a large planting area in China, after the apple tree has entered the later stage of maturity. We should lay reflective film in apple orchard. Laying reflective film can effectively improve the coloring degree of apple fruit and increase the number of all red fruits. If combined with management work such as flower thinning and fruit turning, it is of great help to the yield. So how to spread the reflective film in the apple orchard? The following editor will give you a brief introduction, let's have a look!

1. Selection of reflective film

Now there are many reflective films available on the market, and the quality will be different, so we must pay more attention to them when choosing reflective films. Should be based on reflective properties, moisture-proof, anti-oxidation and so on, the material is generally polypropylene, polyester aluminum foil, it is appropriate to choose double-sided composite film. The reflective rate of this reflective film can generally reach about 65%, and the use time can also reach 4 years, which can reduce the input of the reflective film. There is also a single layer aluminized film, although the price is relatively cheap, but the quality is very poor, the longest service life will not exceed 4 years, so it is generally not recommended to choose this reflective film.

2. Orchard selection

When laying reflective film, it is necessary to ensure that the orchard has a good permeability, not in the closed orchard. If the orchard is closed and the permeability is poor, the effect of the reflective film will be greatly reduced. And if there is not a high level of management, planting efficiency is not ideal, mainly in the low-grade market, then it is not recommended to lay a reflective film. Because the laying of reflective film to ensure that the orchard has a high level of management, with high-quality fruit as the production goal of the orchard. The planting efficiency is high, the return is fast, and it can also give full play to the laying effect of the reflective film.

3. Prepare before laying the film

Before we film the apple orchard, we must first make preparations. The soil in the orchard should remove weeds and drop fruit in time, and then prepare the soil according to the direction of the apple tree, keep it in the form of high inside and low outside, and the height should be controlled at about 82cm. Avoid stagnant water of reflective film and affect reflective efficiency. Then the overgrown branches, over-dense branches and overlapping cross branches of apple trees should be cut off to improve the permeability of apple trees. If the branch is useful, then pull the branch properly. Finally, for the drooping branches, it is necessary to keep the distance between the branches and the ground by means of truncation and retraction.

4. Timely film laying

The time to lay the reflective film should generally be about 4 days after picking the bag, if there is no bagging, then the film should be laid about a month before picking. The dense planting apple orchard should be laid mainly between rows, on the contrary, if it is arboreal planting, it should be laid in the shadow of the crown. No matter what the laying method is, it should be laid along the direction of the apple tree line. Put the reflective film at one end of the line, generally return the shop, and then fix the reflective film with stones. The reflective film should not be too tight to prevent the sudden drop in temperature from tearing the reflective film. Then the sundries on the reflective film should be cleaned regularly to ensure the reflective efficiency.

The above is a brief introduction to how to spread the reflective film in the apple orchard. That's all for today's introduction. This article is for reference only. I hope it can help you all.
