Avocado fertilization management technology, what fertilizer to use for avocado

1. Base fertilizer

Before planting avocados, you need to apply enough base fertilizer to the soil. Base fertilizer is generally farmyard manure, which has a relatively long effective time. This type of fertilizer is usually made from crop straw and animal manure. After they are mixed and sealed, they can be fully decomposed to exert their fertilizer effect. Fertilizers that are not fully decomposed may cause fertilizer damage, and the heat generated during the fermentation process may burn the roots.

2. Topdressing

1. Before flowering: Avocado needs to consume certain nutrients to bloom, so appropriate topdressing is needed before flowering so that the plant can grow better. The fertilizer at this time is generally manure, which can be well absorbed without the need for conversion, and potassium and nitrogen elements should also be appropriately supplemented.

2. Fruiting period: Whether the avocado fruit grows well or not is also related to whether there is sufficient nutrients, so it is necessary to fertilize it at this time. At this time, in order to ensure the growth of the fruit and prevent it from falling, quick-acting fertilizer should be applied. The faster it takes effect, the more helpful it will be for the fruit.

3. Swelling period: The swelling period of avocado fruits is generally in July. In order to make the fruits develop better, the third topdressing is needed. The fertilizer this time is the same as that used during the fruit-bearing period, and a fast-acting chemical fertilizer is also needed. Pay attention to controlling the concentration and dosage. Too much fertilizer will also cause fruit drop.

4. After picking: After picking the avocados, fertilizer needs to be added so that the fruit trees can resume growth. The time for fertilization is generally from September to October. Since it promotes the growth of branches and leaves, use more nitrogen fertilizer and combine it with other trace elements to make it grow better.
