Detailed Explanation of Strawberry Mulching and Cold Protection Techniques
Strawberry is a fruit with a relatively high market price in China, but even with its market price, it is still loved by many people. Therefore, strawberry cultivation is still very common now, and after strawberry cultivation enters winter, it is necessary to do a good job of mulching and cold protection. So how should strawberries be mulched? Today, the editor brings you the mulching and cold protection techniques for strawberries. Below is a brief introduction for everyone. Let's take a look!
1. Covering time and materials
Before covering with plastic film, we must first water the soil once with antifreeze water, and the antifreeze water must be sufficient and thoroughly watered. The watering time should be before the soil freezes, and then covering should be carried out about 7 days after watering. When covering, the choice of materials is very important. Not only can the common plastic film be used, but various crop straws, leaves, and fertile soil can also be used. If soil is used for covering, then it is best to first cover with a layer of grass and then cover with soil, to prevent the strawberry plants from being damaged when the soil is removed.

The covering method is actually very simple. Just directly place the selected covering material on the planting plot. However, it should be noted that when covering, it is best to do it in two times. After the antifreeze water has been applied well and the soil is slightly dry, first cover part of the covering material. Then after a few days, when the temperature has not risen, cover it all. When covering, the covering thickness should be controlled according to the local climate and the selected covering material. Usually, a thickness of about 4 cm is sufficient. If it is grass, then the amount used per mu is about 500 jin.
3. Plastic film covering
If plastic film covering is used, then polyethylene transparent film should be selected. After watering the freezing water, wait until the soil is slightly dry, then level the entire bed surface. Then cover the film according to the direction of the bed. When covering the film, pull the plastic film tight and spread it flat. Press it down firmly around the edges with stones or soil, then cover the middle of the film with an appropriate amount of soil piles to avoid wind, and then cover it well with covering material. If there is a lot of snow accumulation, then set up wind barriers for cold protection instead of using plastic film. Wind barriers should be set up about every 12 m, and various tall grain crops can be used, such as sorghum, corn, etc.
4. Removing the covering material
In the spring of the following year, when the soil begins to thaw, start removing the covering material. It is best to do it in two times. The first time should be done when the average daily temperature is above zero, removing some covering material that has completely thawed. Especially when there is a lot of rain and snow in winter, it should be removed in time to allow the lower soil to thaw quickly and provide the strawberry plants with sufficient sunlight. Then, when the strawberries are about to sprout, carry out the second removal of the covering film. The time for removing the covering material should not be too late, to prevent damage to the new stems of the strawberries.
