Broccoli, also known as broccoli, broccoli, broccoli, etc., is a common herb of the genus Brassica, which is a common edible vegetable in daily life in China and has high edible value. Nowadays, broccoli is grown in both the north and the south of China. So, where is the broccoli planted? The planting environment and planting time of broccoli are now described below.

Planting environment of broccoli 1. Illumination: Broccoli does not require strict illumination, but enjoys sufficient light during the growth process. When the light is sufficient, the plant grows robustly and can form a strong vegetative body, which is beneficial to photosynthesis and cultivation. The accumulation of the parts, and the flower ball is tight and compact, the color of the green color is good, and the sun in the summer is too strong, which is not conducive to the growth and development of broccoli. 2. Temperature: broccoli in the range of 5-20 °C, the higher the temperature, the faster the growth and development, the optimum germination temperature is 20-25 °C, the growth temperature at the seedling stage is 15-20 °C, and it has strong cold tolerance. And heat resistance, the growth temperature of the rosette is 20-22 °C, the flower temperature is 15-18 °C, and the quality of the flower ball is easy to deteriorate when the temperature is higher than 25 °C, but as long as it is not affected by freezing, the flower ball is 5 °C or even lower temperatures can still grow slowly.
Moisture: Broccoli requires a lot of water during the whole growth process, especially when the leaves are vigorously growing and the flower bulb formation period is more water-deficient. Even short-term drought will reduce the yield, and the seedling period is rainy or the soil moisture is too high. Black rot, black spot disease and other diseases, the soil moisture in the field of flower formation is about 70-80% in the field to meet the growth needs. 4. Soil: broccoli does not require strict soil conditions, but if it is too poor, the plant is poorly developed, the yield quality is low, and the soil is too fertile, which will lead to loose flower buds and hollow flowers, suitable for irrigation and drainage, deep plough layer and loose soil. Planted on loam and sandy loam with high fertility and water conservation, the soil pH range is 5.5-8, but 6 is the best.
Broccoli planting time Broccoli planting time is usually started in the autumn, winter growth, normal listing on the table after the Spring Festival, spring flowering until April and May seed maturity, summer and autumn seedlings in the high temperature season in August - October breeding, this When the temperature is generally above 25 ° C, sometimes 30-35 ° C high temperature, coupled with heavy rain, hail damage, so the use of shading net in the open field nursery, the seedling age is generally 35-40 days, can be used for sowing or direct seed The average seedling period is about 30 days. From colonization to harvesting for 80-90 days, the winter is slightly stronger, and the seedling stem diameter of 10 mm can accept the low temperature effect and complete the vernalization process.
