Broccoli, commonly known as broccoli. Originated in Italy, it is a common vegetable. Commonly known as green cauliflower, also known as broccoli. The biennial herb is a variety of cabbage. The leaves are large, and the top of the main stem forms a hypertrophic flower ball, green or purple-green, the small flower buds on the surface are not densely packed, and the top of the side branch has small flower balls.The morphology and growth habit of broccoli are basically similar to those of cauliflower, but it grows vigorously and has strong heat and cold resistance.
Nutritional valueThe nutrients in broccoli are not only high in content, but also very comprehensive, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene. In addition, broccoli has a more comprehensive mineral composition than other vegetables, and the content of calcium, phosphorus, iron, potassium, zinc, and manganese are very rich, which is much higher than that of cabbage flowers that belong to the same cruciferous family.Many people think that tomatoes and peppers are the most vitamin C-rich vegetables. In fact, the vitamin C content of broccoli is higher than them, and it is also significantly higher than other ordinary vegetables. Moreover, broccoli has a very complete variety of vitamins, especially the rich content of folic acid, which is also an important reason why its nutritional value is higher than that of ordinary vegetables.
How to Plant Broccoli Seeds1. PreparationFor growing broccoli, choose loamy soil that is dry, well-drained, aerated and light, rich in organic matter, and cultivated, fertilized, disinfected and weeded before planting. At the same time, the soil moisture must be adjusted to the seeds. If the soil moisture is too little, it will affect the expansion and germination of the seeds. If the humidity is too high, the soil is closed.
2. Sowing seedsSoak the seeds in warm water at 50 °C for 25 minutes before sowing to kill germs that have penetrated the seeds. Broccoli can be planted in open ground after Qingming in spring or in late summer and early fall and can be planted from July to October in Zhejiang. The treated broccoli seeds are then sown evenly onto the prepared seeds, covered with fine soil and sprayed with a fine nozzle to keep the seeds and the waxy surface attached. close
3. ManagementDuring the entire germination period, it is necessary to observe the field in the morning and in the evening to observe seed germination, soil moisture on the threshed surface and the intensity of sunlight or drainage on rainy days. During the hot sun and high temperatures from July to September, most of the germination and seedling stage relies on watering to adjust the soil temperature so that the soil temperature is maintained at a suitable temperature of 25-30 °C to facilitate. Convenience in normal emergency situations Watering can be done in the afternoon and evening to avoid rainy weather after watering. During this time, cover a few sunshades day and night to keep cool and rainy, and wait for both emergency cotyledons to open the sunshade when they turn green.
4. TransplantingBefore transplanting, use field manure as a base fertilizer, regularly tilling and tillering, planting and cultivating in the rainy season by planting in open ground 2 rows 1 m high, dry season with flat trellis and wide fields. Planting and mulching with plastic film for autumn and early spring plantings. When planting, try to bring as much soil as possible, destroy less roots, shorten the slow seedling period and after transplanting. There should be a strong water management.
