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 planting, it will cause fertilizer burn: the luster of the strawberry leaves disappears, 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 learn about it together with the editor.
I. Causes of fertilizer burn in strawberries
1. Excessive fertilization
Sometimes growers, in order to speed up vigorous strawberry growth, 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 strawberry root system has weak activity, the absorption of nutrients is relatively low, leaf transpiration is reduced, and tolerance to salt is relatively low. At this time, if a large amount of fertilizer is applied, it very easily causes fertilizer burn in strawberries.
⟦NL>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 applied organic fertilizer or farmyard manure has not been fully decomposed, under high-temperature and high-humidity conditions it will quickly 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 expel the high-concentration ammonia and other harmful gases from the greenhouse.
3. Water in time
After fertilizer burn occurs, clean water can be sprayed immediately 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.
