How to solve the fertilizer damage of strawberry at seedling stage

Strawberry fertilizer needs a large amount, but it is not very good to grasp when fertilizing, too little fertilization, nutrition supply is not in place, plant growth is poor, too much fertilization will occur fertilizer damage. And in strawberry seedling stage is easy to appear fertilizer harm, so strawberry seedling fertilizer harm how to solve it? Let's take a look.

1. Causes of fat damage

First of all, the organic fertilizer has not been fully decomposed, and the greenhouse high temperature and high humidity environment, fertilizer in the decomposition process produced high temperature, causing seedlings to burn roots, even if the fertilizer decomposed, but also because of excessive fertilization, closer to the roots, will also cause strawberry seedlings fertilizer damage, after strawberry planting, slow success, and give strawberries a lot of inorganic fertilizer, then strawberries will also appear fertilizer damage phenomenon. When fertilizer is used too much and its concentration is low, it is also easy to cause strawberry seedlings to appear fertilizer damage, and if the foliar fertilizer concentration is too high, it will also appear fertilizer damage.

2. How to avoid fat damage

When fertilizing strawberries, we must control the amount. We should not apply too much fertilizer at one time, especially nitrogen fertilizer. Organic fertilizer must be applied after full decomposition. Half a month before transplanting, apply base fertilizer into the field, and transplant after watering or rainfall. When spraying foliar fertilizer on strawberries, it should be carried out on cloudy days or sunny evenings, and should not be sprayed at noon, because this is a high temperature and rapid evaporation of water, which will cause excessive concentration of foliar fertilizer and cause fertilizer damage.

3. Solution

In the occurrence of fertilizer damage, first of all, timely hydration, generally using drip irrigation for hydration, can be supplemented several times, but each time to pay attention to the amount of hydration, so as not to appear ponding root. Or spray some green protection or spray some brassin, also can alleviate fertilizer damage. If fertilizer damage occurs before plastic film mulching, then do not rush to cover plastic film first, you can water properly, reduce fertilizer concentration, this can also reduce fertilizer damage appropriately. If fertilizer damage occurs after covering the film, and the ammonia smell is particularly heavy, then the film should be removed and these harmful gases discharged. After the seedlings slow down, ethylene foliar fertilizer can be sprayed, such as amino acids or humic acid, but try not to apply chemical fertilizer.

The above is how to solve the problem of strawberry seedling fertilizer, I hope to help you, want to know more related knowledge, please pay attention to us.
