What kind of flowers should be planted in greenhouse? Is management difficult?

The minimum scale of flower cultivation is about 2 mu of land. Generally, 2-5 kinds of flower plants can be planted on 5 mu of land, and only one kind of plant is too monotonous to be busy in the harvest season. There are still many flowers and plants suitable for planting in Beijing, such as Chinese rose, chrysanthemum, gerbera, sunflower, snapdragon, violet, corn poppy, marigold, eustoma grandiflorum, Senecio scandens, Ye Mudan, delphinium, Lonicera japonica Thunb., Celosia japonica Thunb., Celosia cristata Thunb., Shell flower, Campanula bella, Marigold, Cuiju, and Pinhead fruit. 5 mu of land can be used for communication in spring and summer without building a plastic shed, and it is better to build it in late autumn and early winter. The investment in greenhouses is relatively large, generally, a greenhouse with a length of 4 meters and a width of 8-1 meters needs about 1, yuan (a general greenhouse). The flowers planted in summer mainly include sunflower, amaranth, fruit with a nail head, chrysanthemum, cockscomb, rose, chrysanthemum, platycodon grandiflorum, marigold, ornamental pumpkin and ornamental corn. In winter, rose, gerbera jamesonii, chrysanthemum, marigold, corn poppy, shell flower, violet, delphinium, snow pearl flower and Pulsatilla are suitable in greenhouse. If you want to get better benefits, you must build a greenhouse in late autumn and early winter. Only by producing all the year round can you ensure the greatest benefits. First of all, on the basis of technical conditions, it is impossible to cultivate successfully without technology. Investment is related to the types of flowers planted, and different flower varieties have different investment amounts. About 5 mu of land needs thousands of pieces in summer, but to build a greenhouse, it is necessary to increase investment.
