The latest fertilization method of pineapple

Pineapple We also call it pineapple, pineapple and jackfruit are tropical fruits, although the nutritional value of jackfruit is higher than pineapple, but more people may prefer the taste of pineapple, because pineapple ripens after a fragrance, very good smell, let people smell want to taste a bite. In recent years, the planting technology has improved, and the planting range of pineapple has expanded, so today, the pro-agricultural network will teach you how to fertilize pineapple.

1. Heavy application of base fertilizer

Base fertilizer is the most fertilizer required for the whole growth period of pineapple, because it needs to meet the growth needs of pineapple for at least one year, so base fertilizer plays a very important role in the whole growth process of pineapple. Only by applying sufficient base fertilizer, pineapple yield can be guaranteed. We generally use farm manure or organic fertilizer for base fertilizer. Of course, we can mix appropriate amount of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer in the middle. Among them, phosphorus fertilizer is used in a large amount. We need to pay attention to reasonable matching, otherwise it will backfire.

2. Frequent application of seedling fertilizer

Pineapple seedlings need to grow to a certain period of time before they bear pineapple. Its growth period takes at least six or seven months, so we can apply less fertilizer each time, but we must apply it frequently, so that we can better grasp the nutrient consumption required for pineapple growth. For example, apply it once when pineapple seedlings grow about nine leaves, apply it once when they have twenty leaves, and apply it once before flowering. The first and second times are mainly nitrogen fertilizer, supplemented by phosphorus fertilizer and potassium fertilizer, and the third time is mainly potassium fertilizer, supplemented by phosphorus fertilizer and nitrogen fertilizer. Don't remember wrongly, because if nitrogen fertilizer is applied for the third time, the flowering period will be delayed, thus missing the best fruiting period.

3. Scientific fertilizer

If there is no problem with seedling fertilizer, then the flowering period is generally in December, so we can apply flower fertilizer at the end of November, of course, we can also apply it in December, but if we start applying flower fertilizer at the end of November, it can promote flowering, increase fruit setting efficiency, and protect the fruit well. The phenomenon of fruit drop will be greatly reduced. We can use urea and potassium fertilizer in a ratio of one to one for watering, so that the fruit size is more stable and looks very neat.

4. Reasonable fruit fertilizer

Fruit fertilizer is a key step, because it not only determines the yield and quality of pineapple this year, but also determines the resistance of next year's plants and the yield of next year, so our fertilization must be scientific and reasonable, not only to ensure this year's yield but also to celebrate the resistance of plants. Fruit fertilizer We normally use potassium fertilizer as the main fertilizer, and spray with appropriate amount of boron fertilizer, which can not only achieve the effect of strong fruit, but also accelerate ripening and shorten the growth period. Secondly, we can spray appropriate amount of gibberellin to ensure the weight of fruit.

5. Heavy application of maintenance fertilizer

In fact, the maintenance fertilizer is equivalent to the base fertilizer of the second year, so the maintenance fertilizer needs to be applied again, and it must be applied sufficiently. We apply the maintenance fertilizer one week to two weeks after pineapple harvest. The fertilizer dosage is consistent with the base fertilizer, but this time it is mainly irrigated with potassium fertilizer and nitrogen fertilizer mixed with water, which is conducive to plant absorption.
