Answer: Chang Zongtang, a consultant from the Old Association of Science and Technology in Yangling Demonstration Zone and a researcher at Northwest A&F University, replied: Cauliflower is a semi-cold-tolerant vegetable. It prefers a mild and cool climate, avoids heat and drought, and is intolerant of frost. The suitable temperature for the growth of flower bulbs is relatively narrow. Only by arranging the growth time of the flower bulbs within the suitable temperature range according to the growth period of the variety, can the cultivation achieve the ideal harvest. Recently, the temperature has dropped and the weather has become colder. Cauliflowers have been extended in autumn in the greenhouse. Ventilation openings should be covered at night and short-time ventilation during the day to promote the fullness of the flower bulbs. Open autumn cauliflower can be harvested to prevent freezing damage. Conditional growers, if the flower bulbs of cauliflower are not fully enriched, plastic film can be used to cover the cauliflower plants, and the film can be pressed to prevent the wind from blowing away, which can promote the continued enrichment of the flower bulbs.
