What are the requirements for the growing environment of broccoli? Broccoli is a kind of autumn and winter vegetable, which likes warm and humid climate, has wide adaptability and is easy to cultivate. The plant is strong, heat and cold tolerance is stronger than cauliflower. At a certain seedling age, the flower bud begins to differentiate at a low temperature, and the optimum temperature for seed germination is 20-30 ℃, and the suitable temperature for growth and development is 15-18 ℃. Higher temperature is needed in the early stage of growth, the optimum temperature is 18 to 25 ℃, and the suitable temperature is 15 to 18 ℃ in the later stage (flower ball formation stage). If the temperature in the later growth stage is too high (22 to 25 ℃), the formation of the flower head is blocked, the loose quality of the flower ball is poor, and the yield is low. The resistance to heat and cold was strong in the seedling stage, but the resistance became weak in the middle and later stage of growth, and the growth was slow below 5 ℃. Broccoli is a low-temperature long-day plant, like light, lack of light, the plant grows too long, the color of the flower bulb turns yellow, affecting the quality, so when broccoli cultivation, the light should be sufficient, the bulb must see the sun, can not be covered by leaves. Broccoli prefers moist environment and needs more water, especially in the period of bulb formation after flower bud differentiation, which inhibits the formation of bulb and reduces the yield and quality. Broccoli has strict requirements for soil nutrients, and the loam or clay loam with deep, fertile and well-drained soil is more suitable, and the PH value of 6.0 is the best. Broccoli is a kind of fertilizer-tolerant vegetable, which needs sufficient nitrogen nutrition in the whole process of growth and development. The ratio of nitrogen, phosphorus and potassium is 14 ∶ 5 ∶ 8. Broccoli has special requirements for trace elements such as boron, magnesium and molybdenum. Boron deficiency will cause yellowing and browning of flower buds and cauliflower cracks. Therefore, attention should be paid to the application of boron, magnesium and molybdenum fertilizer during cultivation.
