To no cost to protect the grapes from being eaten by birds, you can make a pinwheel out of plastic bottles. They rotate in the wind and create glare, thereby scaring the pests. Beyond the practical benefits, homemade turntables of the bottles are always beautiful, which was interesting to watch in windy weather.
- plastic bottle 1.5-2 liters;
- food foil;
- double sided tape or glue;
- thin rods or wire.
The process of making and installing fans
On the Central part of a plastic bottle is the markup under the blades.
You need to split it into 5 lobes. The width of each of them of about 4 cm, the spacing between blades of about 3 cm the Actual dimensions depend on the diameter of the particular bottles. It is important that the blade came out of the same and placed symmetrically. In this case, they will spin even with a light wind.
Using a utility knife to cut each blade with three sides. The cut is performed by cross marks and one longitudinal. Then the blades are curved at a right angle to the outside. Also need to drill the bottom of the bottle in the center. The hole diameter should be slightly greater than the thickness of the prepared for installation of fans of twigs or wire.
Then on the blade is glued foil. Safest to do it with the help of double-sided tape, it will not allow it to fall off even after months in the rain. It can be glued on the glue. Also for this purpose instead of foil fit heat reflective adhesive trim screen for radiators of heating.
For mounting, the hole bottom is inserted a twig or wire. Its end inside of the bottle rests on the cap. In the lid you need to make a small indentation with a drill bit. The axle should rest on him, she will always be in the center. When the wind spinner rotates, the foil blades creates a glare. All of this deters the birds.
Need to do a few of these impellers and place them around the vineyard. The pins from the turntable attached to the top trellis of the grapes so that the vine with the proliferation of them is not closed.
The same impeller can be installed on strawberry plantations, tied above the crown cherry, black cherry, peach. For the manufacture of a turntable takes no more than 10 minutes, so with 1 hour you can make enough of them to place around the area. Also like Scarecrow to deal with the chirping in the morning near the open Windows birds.
