What are the effects and functions of broccoli? What can't you eat with? Attached cultivation conditions

Broccoli is a common vegetable in our life, and many friends call it broccoli. Broccoli is nutritious and comprehensive, and its vitamin C content is even higher than that of pepper. So what are the effects and effects of broccoli? What can't broccoli eat with? And what are the cultivation conditions of broccoli?

I. the efficacy and function of broccoli

According to traditional Chinese medicine, broccoli has the effects of tonifying kidney and essence, strengthening brain and bone, tonifying spleen and stomach, eating more broccoli, which can treat chronic diseases such as body deficiency, limb impotence and weakness, tinnitus and forgetfulness, weakness of spleen and stomach, growth retardation in children and so on. Specifically, the efficacy and function of broccoli have the following aspects:

1, broccoli contains antioxidant anti-cancer trace elements, long-term consumption can prevent breast cancer, rectal cancer and gastric cancer and so on.

2. Broccoli is one of the foods with the most flavonoids. Flavonoids prevent infection, prevent cholesterol from oxidizing, prevent platelets from clotting, and reduce the risk of heart disease and stroke.

3. The rich content of vitamin C in broccoli can enhance the detoxification ability of the liver, improve the immunity of the body, and prevent the occurrence of cold and scurvy.

4. Broccoli has the effect of killing Helicobacter pylori, which causes gastric cancer.

5. Broccoli is a high-fiber vegetable, which can effectively control the condition of diabetes.

6. Children often eat broccoli, which can promote growth, maintain normal teeth and bones, protect eyesight and improve memory.

7. According to the research of cytology and molecular biology, broccoli, garlic, tea and other foods have a protective effect on the optic nerve and can be used as a dietary therapy for patients with ophthalmopathy.

8. Broccoli contains a chemical called sulforaphane, which "activates" a protective protein in blood vessels to form its own defense system to avoid vascular blockage.

9. Sulforaphane, extracted from broccoli, helps people keep their minds sharp in old age.

What can't broccoli be eaten with?

1. Zucchini: broccoli is rich in vitamin C, and the encounter of vitamin C decomposing enzymes in zucchini will affect the body's absorption of vitamin C and reduce the nutritional value of broccoli.

two。 Milk: after drinking milk, and then immediately eat broccoli, will affect the absorption of calcium, two kinds of food together will reduce the nutritional value.

3. Animal liver: such as pig liver, chicken liver, broccoli is rich in dietary fiber, which will combine with copper, iron, zinc and other elements in animal liver to form indigestible substances, thus affecting the absorption of the body.

3. Cultivation conditions of broccoli

The main results are as follows: 1. The requirements of light for western blue flowers are not very strict, but they like sufficient light in the process of growth, and when the light is sufficient, the plants grow healthily, which can form strong nutrients, which is conducive to photosynthesis and nutrient accumulation, and make the bouquet compact and compact. Bright green color is good, too strong sunshine in midsummer is also not conducive to the growth and development of western blue flowers.

2. When the temperature is in the range of 5 ℃ and 20 min, the higher the temperature is, the faster the growth and development of western blue flower is. The optimum temperature for germination was 20 ℃, and the optimum temperature for growth at seedling stage was 15 ℃. The western blue flower has strong cold and heat tolerance. The suitable temperature for growth at rosette stage is 20 ℃ 22 ℃, and the suitable temperature for flower head development is 15 ℃ 18 mol. When the temperature is higher than 25 Mel, the quality of the flower head is easy to deteriorate, but as long as it is not damaged by freezing, the flower head can still grow slowly at low temperature of 5 ℃ or below. There are great differences in temperature requirements for vernalization among different varieties and seedling ages, so the selection of varieties in annual cultivation is very important.

3. Water demand is large in the whole growth process, especially in the period of vigorous leaf growth and flower head formation, even if it is short-term drought, it will reduce the yield. Rainy or high soil moisture at seedling stage can easily cause diseases such as black rot and black spot. During the period of flower head formation, the soil moisture and field capacity are about 70% and 80% in order to meet the growth needs.

4. The soil nutrient West Blue flower is not strict on soil conditions, but if it is too barren, the plant will develop poorly, and the yield and quality will be low, while the over-fertile soil will lead to loose buds and hollow moss. West blue flower is suitable to be planted on loam and sandy loam with good drainage and irrigation, deep plough layer, loose and fertile soil, strong water conservation and energy conservation. The range of soil pH was 5.5 Mel 8, but 6 was the best. Broccoli needs sufficient fertilizer in the whole growth process, and its ratio of N, P and K is 14:5:8. The demand for nitrogen was relatively high at the seedling stage, and the demand for P and K was relatively increased after flower bud differentiation. It is noted that boron, molybdenum, magnesium and other trace elements are also required in the process of flower head development, so the application of appropriate trace element foliar fertilizer before budding will significantly improve the yield and quality.
