Monband® solution ensures strawberries grow vigorously after being covered with mulch film

At present, as the temperature gradually drops, some strawberries are beginning to bud. At this point, you can begin to apply mulch film to the strawberries. Before laying plastic film on strawberries, it is necessary to understand the role of laying plastic film and related precautions.

·The role of strawberry mulch film

1. Conserve soil moisture. Strawberry roots are wet and intolerant of waterlogging. Therefore, it is necessary to keep the soil moisture balanced and avoid sudden dry and wet, which is not conducive to the growth of strawberry roots.

2. Ensure soil temperature. Avoid water evaporation leading to soil temperature reduction. The most suitable temperature for strawberry root growth is 15-22 degrees, so it is necessary to lay mulch film in winter to achieve the purpose of heat preservation. Reducing the evaporation of water in the soil can also prevent the rise of deep water to bring up salt in the soil.

3. Reduce the humidity in the shed to reduce the occurrence of diseases. Temperature decreases in winter, it is not possible to open the shed regularly. How to control the humidity in the shed after watering is a problem. In this case, the mulch can effectively reduce the temperature in the shed and reduce the occurrence of diseases such as gray mold.

4. Suppress the growth of weeds. Herbicide can not be used in the later stage of strawberry planting, so when laying mulch film, use black color can prevent weed growth, save time and labor. Or choose silver-gray mulch, which is conducive to strawberry color change.

5. Avoid fruit surface contamination. Laying plastic film can effectively isolate the direct contact between strawberry fruit and soil. Avoid degradation of fruit quality due to surface contamination.

·Strawberry mulching precautions

1. Time for mulching. Mulch film will raise the temperature of the ground. According to recent measurements, laying plastic film when the temperature is 18 degrees on a sunny day will increase the ground temperature by about 2-3 degrees, increasing the risk of strawberry frondent growth. However, it can not be laid too late, if the flower branches stretch, the mulch will damage the flower branches. Therefore, under normal circumstances, the plastic film should be laid after the strawberry buds and no longer need to control the bloom. According to the growth of strawberries, weak seedlings spread early, strong seedlings spread late.

2.Cover the old leaves, side buds and stolons before spreading mulch film. On the one hand, it makes the operation of mulching film more convenient, on the other hand, it can reduce the waste of nutrients. According to the growth of strawberries, if the growth is strong, a few leaves can be left to control frondent growth and promote flowers. If the bud is weak or has appeared, the nutrients required at this time are increased, and too many leaves cannot be hit. Just knock off the old leaves that are not functional, and leave at least six leaves to ensure bud development.

3. Pest control. The operation of beating the old leaves before applying the mulch and applying the mulch will cause wounds to the leaves, so it is necessary to apply the medicine again. In order to prevent powdery mildew, gray mold and other diseases as well as thrips, aphids, two spot leaf mites and other pests.
