What are the causes of fertilizer burn in strawberries and what are the remedial measures?
Growing strawberries is inseparable from fertilizer, but if strawberries are fertilized improperly during cultivation, fertilizer burn can occur: the leaves of the strawberries lose their luster, the edges also become dry, and the whole plant droops listlessly. So what causes fertilizer burn in strawberries? How should it be solved? Let's find out together with the editor.
I. Causes of fertilizer burn in strawberries
1. Excessive fertilization
Sometimes growers, in order to speed up the vigorous growth of strawberries, tend to apply large amounts of fertilizer, but this often backfires: excessive fertilizer very easily causes fertilizer burn.
2. Fertilizing at low temperatures
In winter, both the air temperature and the low temperature are relatively low, the root activity of strawberries is weak, the absorption of nutrients is relatively low, leaf transpiration is reduced, and the tolerance to salt is relatively low. If a large amount of fertilizer is applied at this time, it very easily causes fertilizer burn in strawberries.
3. Too little irrigation
After topdressing fertilizer to strawberries, if the amount of irrigation water is too small, the soil salt concentration will become high, which may also cause fertilizer burn in strawberries.
4. Applying undecomposed farmyard manure
During planting, most fruit growers use farmyard manure or organic fertilizer as base fertilizer, but if the organic fertilizer or farmyard manure applied has not been fully decomposed, under high temperature and high humidity it will rapidly ferment and produce a large amount of ammonia harm, or the high temperature will burn the strawberry roots and kill the seedlings. Even if decomposed organic fertilizer is applied, because the amount used is too much and it is concentrated in the strawberry root zone, fertilizer burn may also occur.
II. Remedial measures
1. Stop fertilizing
Once fertilizer burn occurs in strawberries, fertilization should be stopped immediately to prevent the fertilizer burn from worsening.
2. Ventilate and aerate in time
After fertilizer burn occurs, promptly open the junctions of the plastic film to ventilate and aerate, and remove the high-concentration ammonia and other harmful gases from the greenhouse.
3. Water in time
After fertilizer burn occurs, you can immediately spray clear water to dilute the concentration of the fertilizer solution in the soil, quickly restore a good soil environment, and prompt the plants to return to normal.
