Before planting avocados, the soil should be fertilized with enough base fertilizer.Base fertilizer is usually farmyard manure with a long effective time, which is usually made of crop straw and animal manure, mixed and sealed, fully decomposed to play a fertilizer effect.Fertilizer that has not been decomposed may cause fertilizer damage, and the heat emitted during fermentation will burn the roots.
1. Before flowering: Avocado flowering needs to consume a certain amount of nutrients, so it needs appropriate topdressing before flowering, so that the plant can grow better.At this time, manure is generally used as fertilizer, which can be well absorbed without transformation, and potassium and nitrogen should be properly supplemented.
2. Fruiting period: Whether the avocado fruit grows well or not is also related to the adequacy of nutrients, so it is also necessary to fertilize it at this time.At this time, in order to ensure the growth of the fruit, but also to avoid it falling, so to apply quick-acting fertilizer, the faster the effective speed, the more helpful for the fruit.
3. Expansion period: The expansion period of avocado fruit is generally in July. In order to make the fruit develop better, the third topdressing is needed.This fertilizer is the same as the fertilizer used in the fruiting period, which also needs to take effect quickly, pay attention to controlling the concentration and dosage, too much fertilizer will also lead to fruit drop.
4. After picking: After picking the avocado, it is necessary to supplement the fertilizer once so as to restore the growth of the fruit tree.Fertilization time is usually in September to October, because it is to promote the growth of branches and leaves, so more nitrogen fertilizer, with other trace elements, can make it grow better.
