How to keep strawberry roots in the latest winter

When winter comes, it is very important for strawberry growers to keep their roots. Whether strawberries grow well or not depends on the roots. Strawberry root growth when the guarantee of yield, only a good root, can get a higher yield, then winter strawberries should be any root? Come and have a look with the editor.

1. Fertilizer control

In strawberry flower bud differentiation, it is recommended to use less available nitrogen fertilizer, that is, urea, to control the carbon-nitrogen ratio of strawberry to balance root growth and promote strawberry flower bud differentiation. Increasing the C / N ratio of the plant is helpful to promote the growth of the plant and form a strong plant. when the C / N ratio is high, the root system grows faster and the stem and leaf grow slowly. Calcium fertilizer can also promote the growth of strawberry fibrous roots, and the growth of main roots is inseparable from the participation of phosphorus, zinc can promote auxin synthesis, but also promote stem, leaf and root growth, so even trace elements in the surface layer can promote root growth. In addition, water-soluble fertilizers containing humic acid, amino acid and alginic acid can actually be used to promote root growth.

2. reduce the use of plant growth regulators

Many farmers often use plant growth agents to regulate strawberry growth, but plant growth agents actually do not include freight, and plant nutrients basically come from photosynthesis and root absorption. Therefore, it is recommended to reduce the use of plant growth regulators, although the effect is fast, the effect is good, but long-term use will produce dependence, improper use will also cause plant premature senescence, so try not to use it.

3. Pay attention to agricultural operations

Too much soil moisture tends to cause poor permeability, which will inhibit root respiration, and in serious cases, it may cause root asphyxia, especially in high humidity environment, which will aggravate the disease and cause huge phenomena. The solution to this situation is ploughing, which can break the soil consolidation and increase permeability, but pay attention to it during operation so as not to damage the root system.

4. Pay attention to the concentration of fertilizers.

Too high concentration of fertilizer may cause fertilizer damage, especially when the transplanted seedlings are relatively fragile and cause seedling death, so the seedlings are recommended to apply fertilizer for a small number of times according to the time of the soil, not to apply too much fertilizer at one time, lest the roots are damaged and unable to absorb nutrients, resulting in slow growth. The same is true when using pesticides, when using too high concentration of herbicides or improper spraying methods, it may also cause drug damage, so we must pay attention to it.
