Broccoli open-air can be selected in the spring after the Qingming, around April, when the temperature is just suitable for the germination of broccoli, can also be planted in the fall, usually selected in the late summer and early fall planting. Beijing area spring and fall cultivation. It is usually planted in early April and harvested in late May, and planted in early August and harvested in early November in the fall.
7 health benefits of broccoli
1, cancer prevention. Like cruciferous vegetables such as cauliflower, Brussels sprouts, white radish and cabbage, broccoli has anti-cancer and immunity-boosting effects.
2, lower fat. Broccoli is rich in soluble fiber, which helps remove intestinal waste, lower cholesterol levels and control blood lipids.
3, anti-allergy. Studies have found that the active substances in broccoli can reduce the impact of allergens on the human body and lower the risk of allergies.
4, antioxidant. Broccoli is rich in carotenoids, lutein, zeaxanthin and beta carotene and other strong antioxidants.
5, strong bones. Broccoli is rich in calcium and vitamin K. These two nutrients play an important role in bone health and preventing osteoporosis.
6, heart protection. The isothiocyanate substance radish thiols in broccoli has anti-inflammatory properties that can prevent blood vessel damage and protect the heart.
7, help weight loss. Broccoli is rich in dietary fiber, good for digestion, prevent constipation, lower blood sugar, prevent over-eating, and then achieve the purpose of weight loss.
Expanded Information:
Cultivation conditions:
1, light Western bluebells on the light requirements are not very strict, but in the process of growth like sufficient light, light enough when the plant grows strong, can form a strong nutrient body, is conducive to photosynthesis and the accumulation of nutrients, and make the bulb tight and dense, bright green color quality, summer sun is too strong and is not conducive to the growth and development of the western bluebells.
2, temperature within the range of 5 ~ 20 ℃, the higher the temperature, the faster the growth and development of bluebells. The optimal germination temperature is 20~25℃, and the growth temperature of seedlings is 15~20℃.
Western bluebells have a strong cold and heat resistance, rosette growth temperature of 20 ~ 22 ℃, the development of flower bulb temperature of 15 ~ 18 ℃, the temperature is higher than 25 ℃ when the quality of flower bulb is easy to deteriorate, but as long as not freezing, flower bulb in 5 ℃ or even the following low temperature can be still slow growth. Different varieties, different seedling age on the completion of the temperature required for the completion of vernalization of the difference is relatively large, so the choice of varieties in the annual cultivation is very important.
3, water The western bluebells in the whole process of growth in the water demand is large, especially the vigorous growth of leaves and flower bulb formation can not be short of water, even if it is a short-term drought, but also reduce the yield. Seedling period rainy or soil moisture is too high easy to cause black rot, black spot disease and other diseases. Bulb formation period soil moisture field water holding capacity of about 70 ~ 80% to meet the growth needs.
