Avocado fertilization management techniques, what fertilizer to apply to avocados

Article Catalog

1. Base fertilizer

2. Top dressing

When planting avocados, you need to apply base fertilizer. The fertilizer is usually decomposed farmyard manure, which can continue to provide nutrients to the plants. Fertilizer needs to be applied four times during its growth and once before flowering to promote flower opening. Quick-acting fertilizer should be applied once during the fruiting period to help the fruit grow. Fertilizer should also be applied during the fruit expansion period to make it grow bigger. Fertilize once after picking to help it grow again.

1. Base fertilizer

Before planting avocados, you must first apply enough base fertilizer to the soil. Base fertilizer generally uses farmyard manure that has a relatively long effective time. This kind of fertilizer is usually made from crop straw and animal manure. It is mixed and sealed before it is fully decomposed to exert its fertilizer effect. Fertilizer that has not been decomposed may cause fertilizer damage, and the heat emitted during the fermentation process may burn the roots.

2. Top dressing

1. Before flowering: Avocados require a certain amount of nutrients to bloom, so proper top dressing is required before flowering so that the plant can grow better. The fertilizer at this time is generally manure, which can be well absorbed without conversion. At the same time, potassium and nitrogen must be appropriately supplemented.

2. Fruiting period: Does the avocado fruit grow well? It also has something to do with whether the nutrients are sufficient, so it also needs to be fertilized at this time. At this time, in order to ensure the growth of the fruit and prevent it from falling, quick-acting fertilizer must be applied. The faster it takes effect, the more helpful it will be for the fruit.

3. Expansion period: The expansion period of avocado fruit is generally in July. In order to allow the fruit to develop better, a third top dressing is required. The fertilizer used this time is the same as that used during the fruiting period. It is also a chemical fertilizer that needs to be effective quickly. Pay attention to controlling the concentration and dosage. Too much fertilizer will also cause fruit drop.

4. After picking: After picking the avocado, it needs to be supplemented Fertilize once to allow the fruit trees to grow again. The time for fertilizing is generally from September to October. Since it promotes the growth of branches and leaves, more nitrogen fertilizers, combined with other trace elements, can make it grow better.
