Cauliflower is a common vegetable in normal life. Its vitamin C content is particularly high, and its planting area is also very extensive. However, in the process of planting broccoli, the problem of “spraying flowers†​​is often encountered, that is, during the expansion of the flower bulbs, the flower balls are loose and unobtrusive, and individual flower petals are protruding. So how do the vegetable farmers solve the problem when they are "scattering flowers"? Let's take a look. 1, reasonable watering The cauliflower seedling stage is sensitive to water. When the bottom water is sufficient, when the seedling grows a true leaf, the water is poured every 2~3 days, and the water is properly controlled before the seedling is planted. Late-maturing varieties should be properly watered after the seedlings are 2~3 cm in diameter. If the watering is too early or too much, it will cause the leaves to grow long, or the flowers will be scattered, but the watering will be insufficient or delayed, and there will be early indica And scattered flowers. 2, nursery management In the nursery stage, to do a good job of cold protection, you can take a mulch film or tie the grass felt in the north of the sputum, keep the temperature at 17 ° C ~ 20 ° C can not be lower than 8 ° C. When raising seedlings, you can use nutrient or nutrition bag to raise seedlings, and appropriately enlarge the nutrient area of ​​individual plants. This can make the cauliflower form a healthy seedling, that is, 6~8 true leaves, the root system is developed, and the plant height is 15~18 cm. Take a big bandit when transplanting, don't hurt the roots. 3. Balanced fertilization Apply 3000~5000kg of high-quality decomposed organic fertilizer per acre, and then carry out topdressing. In the seedling stage, NPK should be applied together. At the fixed value, 50 kg of diammonium sulfate, 30 kg of potassium sulfate and 5 kg of micro-fertilizer are applied per mu. 4, bundled leaves or hinges In order to prevent the flower ball from turning yellow or yellowish, you can bundle several leaves in the center, or fold 2~3 leaves to the flower ball, but you can't over-tighten or break the leaves, and this method can also prevent scattered flowers.
