1. Cauliflower (scientific name: cabbage. Botrytis L., alias cauliflower, broccoli, etc. , belonging to Brassicaceae [1], is a variety of cabbage. The nutrition of cauliflower is richer than that of ordinary vegetables. It contains protein, fat, vitamins A, B, C, E, P, U and minerals such as calcium, phosphorus and iron. Distributed in China, the former Mediterranean coast.
Its shape is silique cylinder, 3-4cm long, with midvein 1, thick under beak and thin on beak, and length 10- 12mm. Seeds broadly elliptic, nearly 2 mm long, brown. There is a 1 milky white fleshy head at the top of the stem, which is composed of total pedicels, pedicels and undeveloped flower buds. Racemes terminal and axillary; Flowers are pale yellow and then turn white.
Biennial herb, 60-90 cm tall, covered with frost. The stems are erect, stout and branched. Basal leaves and lower leaves are oblong to elliptic, 2-3.5 cm long, grayish green, rounded at the top, spreading, not convoluted, entire or denticulate, sometimes the leaves are downward, with several lobules and wings; Petiole 2-3 cm long; The middle and upper leaves of the stem are small and sessile, oblong to lanceolate, supporting the stem. There is a 1 milky white fleshy head at the top of the stem, which is composed of total pedicels, pedicels and undeveloped flower buds. Racemes terminal and axillary; Flowers are pale yellow and then turn white. Silique is cylindrical, with a length of 3-4cm, a midvein of 1, a thick lower beak and a thin upper beak, and a length of 10- 12mm. Seeds broadly elliptic, nearly 2 mm long, brown. It blooms in April and bears fruit in May.
3. Cauliflower has developed root system and strong regeneration ability, which is suitable for seedling raising and transplanting. It is easy to freeze below 0℃, and it is difficult to form flower balls above 25℃. The growth and bolting of leaves need warmth, and the suitable temperature is 20-25℃. The formation of flower ball goes through the stage of low temperature vernalization. Cauliflower is not strict with light conditions, but strict with water, and it is neither waterlogged nor drought-tolerant. It has strong adaptability to soil, but sandy loam with high organic matter and deep soil layer is the best. The suitable soil pH value is 5.5-6.6. Strong salt tolerance, it can still grow normally in soil with 0.3%-0.5% salt.
