Methods and points for attention of laying reflective film in apple orchard

Laying reflective film in apple orchard can promote better coloring of fruit, make fruit color become more red, and also greatly improve the economic value of fruit, which is an effective plant measure. So how to lay a reflective film on apple plants? What should we pay attention to? Let's get to know it with the editor.

1. Selection of film and garden

At present, there are many manufacturers producing reflective film in the market, and the quality is also intermingled with the good and the bad. Generally, the good quality is the pure material double-sided composite film of polypropylene, polyester aluminum foil and polyethylene material. This kind of reflective film has good flexibility, high reflectivity and strong anti-oxidation ability. It can be used continuously for more than 5 years. The orchard laid must also require poor permeability, the orchard is not closed, and there is little hand-over between rows. If the orchard is not permeable, the orchard is closed and the transition between rows is serious, the effect will be poor even after laying the reflective film.

2. Film laying

When laying the reflective film, it should be high inside and low outside, so that Rain Water can flow between the lines, so as to prevent the film surface from affecting the luminous effect because of stagnant water, the soil should not be used when pressing the film, and the film surface should not be pulled too tight to avoid a sudden drop in temperature. The second is to strictly cover the film, from the apple bag after the fruit began to color to harvest, inside and outside the tree plate, should be laid strictly.

3. Matching technology

In order to increase the fruit chromaticity, the laying of reflective film should be combined with other management techniques, such as fruit bagging, leaf picking, branch pulling, autumn pruning and so on, so as to increase the effect of reflective film. When picking leaves after picking bags, the total amount of leaves picked should not exceed 30% of the total leaves of the whole plant, which will have no adverse effect on the tree potential and yield in the coming year. In order to make the fruit coloring comprehensive, it is necessary to turn the sunny side of the fruit coloring to the shady side and the poorly colored negative side to the sunny side.

4. Points for attention

The effect of laying reflective film is poor in closed orchards with poor light transmittance and dense planting orchards with serious transition, so this kind of orchards should increase the number of branches thinning and regulating branches. In addition, we should also pay attention to the topography and direction, the reflective effect of the film, the slope is better than the flat, and the north-south direction is better than the east-west direction. Lies in the wind and rain, it is necessary to re-level the film blown by the wind in time, clean the soil and fallen leaves on the film, and ensure that the reflective effect of the film is good.

The above is the introduction of the methods and precautions of laying reflective film in apple orchard. I hope it can help you. If you want to know more about it, please follow us.
