Causes and control measures of cauliflower flower scattering

Cauliflower, also known as cauliflower and cauliflower, is a kind of vegetable with high vitamin C content, and there will be a lot of problems in the process of cauliflower cultivation, such as loose flowers. Loose flower refers to the cauliflower bulb expansion process, the flower bulb appears loose prematurely, so what is the cause of cauliflower loose flowers? How to prevent and cure it? Let's get to know it.

1. Rational watering

Cauliflower is sensitive to water at seedling stage. Under the condition of sufficient bottom water, when the seedlings grow the first true leaves, they need to be watered every 2-3 days, and the water should be properly controlled before planting. After squatting seedlings, late-maturing varieties should be properly watered when the diameter of the bulb reaches 2-3 cm. Watering too early or too much will cause the leaves to stop, or cause the rosette to scatter flowers, but if the water is underwatered or too late, the flowers will be scattered early. Therefore, the cauliflower should be watered reasonably during the growing period, and the correct time should be grasped. The amount of water should not be too large at one time, and a small amount of watering can be taken many times.

2. Seedling management

In the cauliflower seedling stage is still in the low temperature season, so to do a good cold prevention measures, can be used to cover plastic film or straw felt and other methods to keep the temperature between 17-20 degrees, the lowest not less than 8 degrees. When raising seedlings, we should use nutrition bowls or nutrition bags to raise seedlings and appropriately expand the nutritional area of a single plant, so as to form strong seedlings and lay a solid foundation for high yield. when transplanting, we should carry out with soil and do not hurt the roots.

3. Balanced fertilization

Before planting, 3000-5000 kg of high-quality mature organic fertilizer should be applied per mu as base fertilizer, which can provide sufficient nutrients for cauliflower during the whole growth period. Then in each growth stage and then reasonable topdressing, seedling stage should be reasonable with nitrogen, phosphorus and potassium fertilizer, in planting, 50 kg of diammonium sulfate, 30 kg of potassium sulfate, a total of 5 kg of micro-fertilizer.

4. Bundled or folded leaves

To prevent the bulb from turning yellow or yellowish, bundles of leaves in the center of cauliflower can be cleaned, or 2 or 3 leaves can be folded toward the bulb, but not too tight or broken, and this method can also prevent scattered flowers.

The above is the introduction of the causes and control measures of cauliflower scattered flowers. I hope I can help you. If you want to know more about it, please follow us.
