The differences between cauliflower and broccoli are as follows:
1. Different colors
Broccoli is green, and it is also dark green; Cauliflower is white and yellow.
2. Different nutritional values
Cauliflower contains a large amount of flavonoids, which have good anti-cancer effects when consumed for a long time; broccoli also contains this substance, which is more effective than cauliflower. powerful.
3. Different tastes
The taste of cauliflower is stronger; the taste of broccoli is lighter.
1. Temperature requirements for the growth of cauliflower:
Cauliflower is a semi-cold-tolerant vegetable. It likes mild and cool climates. The suitable temperature range for growth is relatively narrow and it is intolerant of heat and dryness. The minimum temperature for seed germination is 2-3 degrees, but very slowly, and the optimal temperature is 20-25 degrees. The suitable temperature for seedling growth is 15-25 degrees. Seedlings are relatively resistant to cold and heat, but when the temperature exceeds 25 degrees, the seedlings will easily grow leggy.
Slightly larger seedlings can tolerate low temperatures of 0 degrees for a longer period of time. The suitable temperature for rosette leaf growth is 18-20 degrees. The suitable temperature required for flower bulb formation is 15-18 degrees. Lower temperatures and large temperature differences between day and night are more conducive to nutrient accumulation. When the temperature drops below 8 degrees, the flower bulbs develop slowly. When encountering low temperatures below 0 degrees, except for late-maturing varieties, the curds are susceptible to frost damage.
When the temperature exceeds 30 degrees, it is difficult to form flower balls. However, different maturity varieties have different responses to temperature. The optimum temperature for the growth of very early-maturing varieties is 20-25 degrees, and the suitable temperature for early-maturing varieties is 17-20 degrees. However, good leaf bulbs can still be formed at 25 degrees. For mid-late maturing varieties, when the temperature is below 15 degrees, and when the temperature for mid-late maturing varieties is higher than 20 degrees, the curds will be loose and easily encapsulated, forming "hairy flowers", and the quality will decline. The optimum temperature for bolting and flowering is 15-20 degrees. The suitable temperature for pod formation is 20-25 degrees. If the temperature is higher than 25 degrees or lower than 13 degrees, poor pod formation will occur.
2. Broccoli growth environment:
1. Sunlight is still very important for broccoli. It needs a lot of light during the growth process. When there is sufficient sunlight, broccoli will grow. Orchids will grow stronger in all aspects and can form a powerful vegetation, which is of great benefit to the progress of photosynthesis and the absorption of nutrients. Sufficient sunlight can also make the broccoli bulbs grow more compact and not loose. However, it should be noted that too strong sunlight in summer is not conducive to the growth of broccoli.
2. Broccoli prefers a temperature environment of 5-20 degrees. The closer to 20 degrees Celsius in this range, the faster broccoli will grow. The optimal germination temperature is 20 to 25 degrees. The best time to bloom is The suitable temperature is about 22 degrees Celsius, and the most suitable temperature for the growth of broccoli bulbs is about 15 degrees Celsius. Note that when the temperature exceeds 25 degrees Celsius, the quality of broccoli will deteriorate. When it is below 5 degrees Celsius or above 0 Broccoli can still grow slowly at 10 degrees Celsius.
3. Broccoli requires a lot of water. It is most in need of water during the entire growth process, especially when it begins to show leaves and when the flower bulbs grow. Even if it is a few days of drought, it can Reduce production. Of course, when there is too much rain or the water content of the soil is too high, it is easy to cause black rot and black spot disease, so we must pay attention to the appropriate amount of water in the field.
