I plant not the first year strawberry seedling on film. On scientific - it is called mulching. At this type of landing of strawberry the earth gets warm one many quicker and the quantity of weeds decreases. The film does not pass sunlight, and weeds die or grow in depression without light.
However not everything happens smoothly. The film often is torn, and weeds break on light. Here everything depends on its thickness and amount of svetostabiliziruyushchy substance. This substance prevents destruction of film from solar radiation.
I have come trudging half a kilometer of black film 70 thick the microdistrict. Most large farms use such film. Then I have laid film and have planted saplings.
Everything was good, our Siberian winds have not begun yet. Has begun to tear and kolykhat film on wind. Wind reached 20 meters per second. It was necessary to trench in constantly it at the edges the earth, but it did not help. Even it was necessary to get old bricks and to press film that did not parusinit it. However by the end of season the result was sad.
I have understood that the normal method of mulching is not suitable for Siberia. Now I try the method. I do two grooves and I cover them from above with film. I stack part of the earth which I take out from holes nearby that the film remained on the place.
Such form of bed is very effective. Blows it wind less, all water gets to holes and less watering is required, and in the winter of hole are hammered with snow at once and strawberry freezes less. Film I buy not less than 120 microns too. But it is quite expensive and labor-consuming method and is not suitable for big plantations yet.
