What fertilizer is good for cauliflower

Overview of Cauliflower Fertilization

Cauliflower is an annual plant of the genus Brassica in the family Cruciferae. It has poor adaptability and strict requirements on external environmental conditions. In addition to the differences between different varieties, the formation of the flower head is affected by many factors.

If the base fertilizer is insufficient when the cauliflower is transplanted, you can apply an appropriate amount of diluted manure at the same time as watering the seedlings. When the cauliflower enters the rosette stage, 15-20 kg of urea is required per mu.

What fertilizer is good for cauliflower?

Generally, 5000 kg of decomposed organic fertilizer and 30-50 kg of compound fertilizer are applied per mu of cauliflower. If the soil is deficient in calcium, magnesium, or iron, a small amount of medium and trace element fertilizer can be added, mixed with the soil, and then raked and used to make beds.

The best foliar fertilizer for cauliflower is a three-element compound fertilizer. Foliar fertilization is very effective in the soil where cauliflower shows symptoms of fertilizer deficiency and poor fertilizer retention in the middle and late stages of growth and development.

How to fertilize cauliflower

The base fertilizer of cauliflower is very important and should be applied before planting. At the same time, a certain amount of inorganic fertilizer is also required, which is usually applied when the plant is taking shape. This can be done by digging trenches to apply base fertilizer.

About 10 days after planting in spring, apply urea according to the growth of cauliflower and water it in time. When the flower head is the size of an egg, apply triple compound fertilizer, and apply boron fertilizer 1-2 times in combination with foliar fertilization. Spray vegetable and fruit strengthening agent to increase yield and prevent the flower head from becoming black or hollow.

In addition, cauliflower requires sufficient light during its growth period. Like cabbage, it is a low-temperature and long-day crop in terms of development. Therefore, after fertilizing, it needs to be given appropriate light to facilitate the plant to absorb nutrients.
