The market prospect of strawberry is very broad. People like the fruit. In the process of planting, adequate nutrition is the key to the growth of strawberries. If improper fertilization will also cause fertilizer damage, what are the reasons for the fertilizer damage caused by strawberry planting?
1. Reasons for fertilizer damage
The first is that the organic fertilizer has not been fully decomposed, and the high temperature and humidity environment of the greenhouse, the fertilizer generates high temperature during the decomposing process, causing the seedlings to burn the roots. Even if the fertilizer is decomposed, it will be too close to the root due to excessive fertilizer It causes fertilizer damage to strawberry seedlings. After the strawberry planting, when the strawberry is slowly and successfully, a lot of inorganic fertilizer is added to the strawberry, so the strawberry will also appear fertilizer damage. When the chemical fertilizer is used too much and the concentration is low, it is also very easy to cause fertilizer damage to strawberry seedlings. If the concentration of foliar fertilizer is too high, it will also cause fertilizer damage.
2. How to avoid fertilizer damage
When fertilizing strawberries, the amount must be controlled. It is not advisable to apply too much fertilizer at a time, especially nitrogen fertilizer. The organic fertilizer must be applied after it is fully decomposed. Half a month before transplanting, the base fertilizer shall be applied to the ground and watered. Or transplant after rain. When spraying foliar fertilizer on strawberries, choose cloudy or sunny evenings. Spraying is not suitable at noon, because this is because the temperature is higher and the water evaporates quickly, which will cause excessive foliar fertilizer concentration and cause fertilizer damage.
In the event of fertilizer damage, water should be replenished in time. Drip irrigation is generally used to replenish water. It can be supplemented several times, but the amount of water should be paid attention to each time to avoid accumulation of water and roots. Either spraying some biprotector or spraying some brassin can also alleviate fertilizer damage. If the fertilizer damage occurred before the mulching, don’t worry about covering the mulch, you can water it properly to reduce the fertilizer concentration, which can also reduce the fertilizer damage appropriately. If fertilizer damage occurs after the film is covered, and the ammonia smell is particularly heavy, remove the film at this time to allow these harmful gases to drain out. After the seedlings are over, you can spray ethylene foliar fertilizer, such as amino acids or humic acid.
