How to solve the latest fertilizer damage of strawberry at seedling stage

Strawberry needs a large amount of fertilizer, but it is not easy to master when applying fertilizer, too little fertilization, lack of nutrition supply, poor plant growth, excessive fertilization will lead to fertilizer damage. However, fertilizer damage is very easy to occur in strawberry seedling stage, so how to solve strawberry seedling fertilizer damage? Let's take a look.

1. The causes of fertilizer damage

First of all, the organic fertilizer is not fully mature, and in the greenhouse environment of high temperature and humidity, the fertilizer produces high temperature in the process of ripening, causing the seedlings to burn roots, even if the fertilizer is rotten, it will also cause fertilizer damage to strawberry seedlings because of excessive fertilization. After strawberry planting and slow success, strawberries are given a lot of inorganic fertilizer, so strawberries will also appear fertilizer damage. When the chemical fertilizer is used too much and the concentration is low, it is also easy to cause fertilizer damage to strawberry seedlings, and fertilizer damage will also occur when the concentration of foliar fertilizer is too high.

2. How to avoid fertilizer damage

The amount of fertilizer must be controlled when fertilizing strawberries. one fertilization should not be too much, especially nitrogen fertilizer should not be applied too much, organic fertilizer must be applied after full maturity, and then the base fertilizer should be applied to the field half a month before transplanting, and then transplant after watering or rainfall. When spraying foliar fertilizer on strawberries, choose cloudy or sunny evenings, and should not be sprayed at noon, because the temperature is high and the water evaporates quickly, which will cause excessive concentration of foliar fertilizer and cause fertilizer damage.

3. Solution

In the event of fertilizer damage, we should first replenish water in time, generally using drip irrigation to replenish water, which can be replenished several times, but pay attention to the amount of water each time, so as to avoid stagnant water retting roots. Or spray some green care or spray some brassine, can also alleviate the fat damage. If fertilizer damage occurs before plastic film mulching, then do not rush to cover plastic film, can be properly watered, reduce fertilizer concentration, this can also appropriately reduce fertilizer damage. If fertilizer damage occurs after covering the film, and the smell of ammonia is particularly heavy, take off the plastic film and let these harmful gases drain out. After the seedlings have recovered, you can spray ethylene foliar fertilizer, such as amino acids or humic acid, but try not to apply chemical fertilizer.
