Causes and control measures of scattered flowers in cauliflower

Cauliflower, also known as cauliflower, cauliflower, is a vegetable with a high vitamin C content, and there will be many problems in the cultivation process of cauliflower, such as scattered flowers. Scattered flowers refer to the process of cauliflower bulb expansion, flower bulb premature loose, do not embrace the situation, then cauliflower scattered flowers is what causes it? How to prevent it? Let's get to know each other.

1. Reasonable watering

Cauliflower seedlings are more sensitive to water, in the case of sufficient bottom water, when the seedlings grow out of the first batch of true leaves, need to water every 2-3 days, before planting, to properly control water. Late-maturing varieties should be watered properly when the bulb diameter reaches 2-3 cm after squatting. Too early or too much watering will cause the leaves to stop, or cause the flower bulb to scatter, but if the watering is insufficient or too late, it will also appear early and scatter flowers. Therefore, in the growth period of cauliflower to reasonable watering, watering to grasp the correct time, watering amount should not be too large, can take a small number of ways to water.

In the cauliflower seedling stage is still in the low temperature season, so to do a good job of cold-proof measures, you can use mulching or grass felt and other methods to maintain the temperature between 17-20 degrees, the minimum should not be lower than 8 degrees. In the seedling to use nutrition bowl or nutrition bag seedlings, appropriate expansion of the nutritional area of individual plants, so as to form healthy seedlings, lay a solid foundation for high yield, in the transplanting to carry out with soil, do not hurt the root system.

3. Balanced fertilization

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

4. Leaf bundling or folding

To prevent the bulbs from turning yellow or yellowish, bundle and clean a few leaves in the center of the cauliflower, or fold two or three leaves toward the bulbs without tightening or breaking the leaves, and this method will also prevent the flowers from falling apart.
