Broccoli can be planted in the open air after the Qingming Festival in spring. Around April, the temperature is just right for broccoli to germinate. Autumn is usually in late summer and early autumn. It is cultivated in spring and autumn in Beijing. Generally sow in early April and harvest in late May; sow in early autumn in August and harvest in early November. 7 health benefits of broccoli 1. Prevent cancer. Like cruciferous vegetables like cauliflower, Brussels sprouts, daikon, and cabbage, broccoli has cancer-fighting and immunity-boosting properties. 2. Lower blood lipids. Broccoli is rich in soluble fiber, which helps clear intestinal waste, lower cholesterol levels, and control blood lipids. 3. Allergy prevention. It has been found that active substances in broccoli can reduce the impact of allergens on the human body and reduce the risk of allergies. 4. Antioxidant. Broccoli is rich in strong antioxidants such as carotenoids, lutein, zeaxanthin, and beta-carotene. 5. Strong bones. Broccoli is rich in calcium and vitamin K, two nutrients that play an important role in bone health and preventing osteoporosis. 6. Protect the heart. The isothiocyanate sulforaphane in broccoli has anti-inflammatory properties that can prevent blood vessel damage and protect the heart. 7. Help lose weight. Buried broccoli is rich in dietary fiber, which is beneficial to digestion, prevents constipation, lowers blood sugar, and prevents overeating, thereby achieving the purpose of weight loss. Extended information: Western flower cultivation conditions: 1. Lighting does not require strict lighting, but it likes sufficient lighting during the growth process. When there is sufficient light, the plant will grow vigorously and form a thick, curved vegetative body, which is conducive to photosynthesis and nutrient accumulation, making the curd compact, dense, green in color and of good quality. Too much sunlight in mid-summer is not conducive to the growth and development of this flower. 2. When the temperature is in the range of 5~20℃, the higher the temperature, the faster the growth and development of orchids. The optimal germination temperature is 20~25℃, and the optimal growth temperature in the seedling stage is 15~20℃. Western flowers are very cold and heat tolerant. The optimal temperature for rosette growth is 20~22℃, and the optimal temperature for bulb development is 15~18℃. When the temperature is higher than 25°C, the quality of the bulbs tends to deteriorate, but as long as they are not damaged by freezing, the bulbs can still grow slowly at low temperatures of 5°C or even lower. Different varieties and seedling ages have very different temperature requirements for vernalization, so it is very important to select varieties in annual cultivation. 3. Cymbidium requires a large amount of water during the entire growth process, especially during the period of vigorous leaf growth and flower bulb formation. Even short-term droughts can reduce yields. Rainy seedlings or high soil moisture can easily cause diseases such as black rot and black spot. Soil moisture during the flowering stage and about 70-80% of field water capacity can meet growth needs.
