Mulching Technology of plastic Film in greenhouse

Plastic film mulching technology in greenhouse:

1. Film mulching time: after strawberry planting in autumn, plastic film is generally covered before overwintering and before sprouting in early spring, while it is more advantageous to cover strawberries before overwintering in cold areas, and it is more suitable when the average temperature of the day drops to 3-5 ℃.

2. film mulching method: apply some nitrogen, phosphorus and potassium compound fertilizer before film mulching, and clean up the dead branches and rotten leaves. When covering the film, you should choose to cover the strawberry plant with the plastic film in a windless day, so that the surface of the film is not wrinkled and the soil around the film is tightly covered. If the border surface is too long, it can be pressed horizontally at a certain distance to prevent the film from being blown by the wind.

3. Breaking and removing the membrane: after the soil thaws in spring, remove the cold-proof material on the film and clean the surface of the film to make the ground temperature rise and promote the strawberry to sprout earlier. The method is: pull a small hole in the plastic film facing the plant, lift the seedling to the film, and the leaves should be careful when passing through the small hole so as not to damage the stems and leaves. The broken membrane mouth around the plant is compacted with soil to make the plastic film close to the ground and enhance the effect of film mulching.

4. Remove the waste film: remove the waste film in time after berry harvest. Because the waste film is not easy to degrade and pollute the soil. After finishing the work of Guri. Tursun
