How to Protect Strawberry Roots in Winter? A Detailed Guide to the Latest Practical Techniques

With the arrival of winter, there is one point that is very important for friends who grow strawberries, and that is root protection. Whether strawberries grow well or not depends entirely on the roots. Strawberry root growth is the guarantee of yield. Only by nurturing the roots well can a higher yield be obtained. So how should strawberry roots be nurtured in winter? Let's take a look together.

1. Control fertilizer

During strawberry flower bud differentiation, it is recommended to use less quick-acting nitrogen fertilizer, that is, urea. It is necessary to control the carbon-to-nitrogen ratio of strawberries to balance root growth and promote strawberry flower bud differentiation. Increasing the carbon-to-nitrogen ratio of the plant helps promote excessive vegetative growth and form strong plants. When the carbon-to-nitrogen ratio in the plant is high, roots grow quickly and stems and leaves grow more slowly. Calcium fertilizer can also promote the growth of strawberry fibrous roots, while robust main root growth cannot be separated from the participation of phosphorus. Zinc can promote auxin synthesis and can also promote the growth of stems, leaves and roots, so even trace elements in the surface layer can promote root growth. In addition, water-soluble fertilizers containing humic acids, amino acids and alginic acid can actually all be used to promote root growth.

2. Use less plant growth regulators

Many farmers often use plant growth regulators to regulate strawberry growth, but plant growth regulators actually do not contain nutrients. The plant's nutrients basically come from photosynthesis and root absorption. Therefore, it is recommended to use less plant growth regulators. Although they take effect quickly and work well, long-term use will create dependence, and improper use can also cause premature aging of the plant, so try not to use them if possible.

3. Pay attention to farming operations

Excessive soil moisture often causes poor permeability, which inhibits root respiration and in severe cases may cause root suffocation. In particular, a high-humidity environment can also worsen diseases and cause huge problems. The way to solve this situation is intertillage, which can break up soil compaction and increase permeability, but care must be taken during the operation to avoid damaging the roots.

4. Pay attention to concentration when fertilizing and applying pesticides

Too high a fertilization concentration may cause fertilizer damage, especially since transplanted seedlings are relatively fragile, and in severe cases it can cause seedling death. Therefore, for seedlings it is recommended to apply fertilizer in small amounts multiple times according to the soil conditions, and not to apply too much fertilizer at one time, so as to avoid burning roots with concentrated fertilizer. When roots are damaged, they cannot absorb nutrients, causing slow growth. The same is true when using pesticides. When the concentration of herbicide used is too high or the spraying method is improper, phytotoxicity may also occur, so be sure to pay attention.
