Fertilization is an indispensable link in the process of crop planting, and reasonable and appropriate use of fertilizer can help to increase production. Let's take how to fertilize dragon fruit as an example to explain it in detail.

How to fertilize dragon fruit is better?

1. According to the seedling age

Planting 1-2 years of dragon fruit, mainly nitrogen fertilizer, a small number of times, in order to promote the growth of young trees. For fruit trees for more than 3 years, the main nitrogen and phosphorus fertilizers are mainly controlled, which can not only ensure adequate nutrients, but also will not harm the normal growth of the fruit.

two。 According to the growth period

(1) it was carried out from January to February before planting. In the orchard planting pit in the hilly and sloping land, about 40-50 kg of organic fertilizer, such as soil fertilizer, weeds, mushroom fertilizer, livestock manure and livestock manure, and 3 kg of lime were applied in the orchard. The soil mound was used in the flat orchard, and about 15-20 kg of rotten livestock manure or mushroom fertilizer and 1.5 kg of lime were applied to each planting hole.

(2) liquid fertilizer (water fertilizer) of rotten bran cake or water fertilizer of rotten livestock manure is suitable at seedling stage, and thin fertilizer is frequently applied as the principle, each time when new branches sprout and begin to turn green, the liquid fertilizer is about 1.5-2 kg per column. Organic compound fertilizer is also available, and the amount of fertilizer applied each time is about 50-80g/ column. The amount of fertilizer applied from the second year is about 50% more than that of the first year. 80%.

(3) generally, there are 5 main fertilization periods in the whole year.

Cover the tree plate with organic fertilizer in winter: when the branches have completely turned green from December to January in winter, the tree plate is covered with organic fertilizer, 10 kg of mixed organic fertilizer per column, or 15 kg of soil fertilizer per column.

Flower-promoting fertilizer: applied in the first and middle of April, 1-1.5 kg organic fertilizer per column.

Strong flower and strong fruit fertilizer: in the first and middle of June, 0.5-1 kg of rotten bran cake fertilizer and 0.5 kg of organic fertilizer compound fertilizer were applied on each column.

Strong fruit and restoring tree potential fertilizer: in the upper and middle of October, 0.5-1 kg of Norwegian compound fertilizer (N 15: P 15: K 15) and 3-4 kg liquid fertilizer of rotten bran cake were applied per column.

Foliar fertilizer: spraying foliar fertilizer with nutrient solution for 3-5 times at flower bud stage and fruit development stage.

In addition, in the dragon fruit fertilization must be timely, appropriate amount, which can not only ensure the improvement of fertilizer use efficiency, but also as far as possible to ensure that there will not be lack of fertilizer and malnutrition, or fertilizer damage caused by excessive fertilizer.
