What is the planting process of chrysanthemum brain

1. Land preparation and fertilization: Choose a plot with high terrain, good drainage and loose soil, apply 2,000 kg of farmyard manure per mu, and then apply about 40 kg of compound fertilizer. The width of the ridge is 1.5-2 meters, and the depth of the ditch is 10-20 cm.

2. Sowing: There are two planting methods: direct seeding and division and transplanting. Division and transplanting are mainly used for small areas, while direct seeding is mostly used for large areas. Direct seeding is done from early February to early March. Mix the seeds with 4-5 times dry fine soil, broadcast or drill, and sow 1 kg per mu. After sowing, suppress, water the bottom, and then cover the ground with film. After the seedlings emerge, remove the film and keep the surface of the bed moist. Division and transplanting is carried out in early April. Cut off the rooted lateral buds together with a section of old roots and transplant them. There are 3-4 plants in each hole, and the hole spacing is 15 cm × 20 cm. After planting, water enough to establish roots, and apply fertilizer and water after the plants are alive to promote the growth of plants.

3. Management: timely inter-cultivation and weeding, keep the soil moist, avoid waterlogging in the field, otherwise it is easy to cause waterlogging and root rot. Apply diluted human feces and urine during the growing season. After the severe frost, cut down the old piles 5 cm above the ground, remove weeds and dead leaves in the field, and apply 2,000 kg of feces or 20 kg of urea per mu. Cover the greenhouse film in early and mid-December. When the night temperature is below 0℃, cover the ground film and straw curtains for heat preservation. Remove the cover early and cover late. Remove the greenhouse film after the frost period. Chrysanthemum brain has few insect pests, but pay attention to the prevention and control of aphids.

4. Harvest: Greenhouse-grown chrysanthemums can be harvested and marketed in mid-to-late January all year round, while those grown in the open field can be marketed in early April. In the early stage, sickles are used to cut them, and they can be harvested once every 3-4 weeks in spring.
