Cauliflower cultivation methods and precautions

1. Maintenance methods

1. Soil: Cauliflower has a strong adaptability, so it prefers soil with good drainage, loose geology and organic matter.

2. Water: After sowing, water the seeds, apply fertilizer and sprinkle a layer of soil. The cauliflower will sprout in about three to four days. After growing, cauliflower needs to be irrigated frequently. Lack of water will directly affect the growth of cauliflower.

3. Nutrients: The frequency of fertilizing cauliflower should be controlled to once every 7-15 days. Applying seedling fertilizer during the seedling period and compound fertilizer in the later stage will speed up the growth of its roots and stems.

4. Light and temperature: Cauliflower prefers an environment with plenty of sunlight. When exposed to sufficient sunlight, it will grow strong and vigorous, and the flower heads will become compact and of good color. The temperature suitable for its growth is between 20-25℃. If the temperature is too high, it will be difficult for it to grow into a spherical shape, and if the temperature is too low, it may suffer from frostbite.

2. Breeding techniques

1. Intertillage and weeding: During the growing period of cauliflower after fertilization, you should pay attention to frequently clearing the weeds in the soil. You can also loosen the soil appropriately after the rain to better promote the cauliflower's absorption of nutrients.

2. Reproduction: Cauliflower is generally propagated by the nutrient bag seedling method, which requires film bags, nutrient soil, and nutrient bags. Arrange the nutrient bags on the seedbed for sowing, then sprinkle a layer of nutrient soil and water it to keep the soil at a certain humidity.

3. Problem diagnosis and treatment

1. Pests: The pests and diseases of cauliflower include cabbage loopers. At this time, you only need to spray cypermethrin. Because the stems and leaves of cauliflower are large and juicy, they are more susceptible to pests and diseases.

2. Black spot disease: Cauliflower is also prone to black spot disease. At this time, you need to dilute the fenpropimorph emulsion with water and spray it on the cauliflower.

IV. Other issues

1. How to spend the winter: When winter comes, you need to water the cauliflower once to slow down its growth, and then fertilize it once to improve its ability to resist frost. After winter, when spring comes, you need to water it again to promote its growth and nutrient absorption.

2. Is it edible? Cauliflower is edible and contains a lot of dietary fiber and vitamins, so the nutritional value of cauliflower is very good.
