In South China, seedlings are generally sown from early February to early March, and late seeds are easy to lose their germination power. They are planted in early April, and tender stems and leaves can be harvested and put on the market in May. The fine management can be harvested continuously for about 3 years.

II. Key points of planting methods of chrysanthemum cauliflower

1. Land selection and preparation

Chrysanthemum cauliflower is suitable for moist, loose and fertile soil. Soil preparation is needed before sowing and fertilization is needed after loosening the soil, so as to ensure the fertility of the soil.

2. Sowing method

The visual cultivation method (direct seeding or seedling transplanting) adopts sowing cultivation or strip sowing, the seed amount of sowing is 60-70 kg per hectare, the strip sowing is about 10 cm apart, and the seed consumption is 30-37.5 kg per hectare. Early spring seedbed seedling sowing should be covered with medicine and soil to prevent sudden death. The suitable seedling age is 20 ~ 0 days, and the suitable planting period is 3 ~ 4 true leaves.

3. Ploughing and weeding

Before the plant is closed, ploughing and weeding can prevent soil surface hardening and is beneficial to root growth. After harvesting the old stubble stalks before winter, it is appropriate to loosen the soil, cultivate the soil, and apply fertilizer to cover it. Usually about 1500 kg per mu of organic fertilizer is applied to facilitate the smooth overwintering of the plant and the early germination of new shoots.

4. Fertilizer and water management

Chrysanthemum cauliflower should be topdressing once 5 days after planting to promote growth, and then once every 7-10 days, using soil fertilizer combined with urea and compound fertilizer. Pay attention to watering during high temperature and drought in summer, but avoid stagnant water in the field, and pay attention to waterlogging and drainage in rainy season to prevent rotting roots. Chrysanthemum cauliflower has strong branching, fast lateral branch germination and great demand for fertilizer, so the times of topdressing should be increased when cultivated in barren soil.

5. Plant adjustment

Chrysanthemum cauliflower has exuberant growth and strong branching ability, so necessary pruning must be carried out to control plant growth, promote lateral bud branching, facilitate field management and enhance ventilation and light transmission. Usually, when the growth of the plant is not closed, it is harvested and topped to promote the germination of lateral buds. When the plant develops to a certain extent, its height should be controlled at about 30 cm, and the vigorous long branches, disease and insect branches and withered branches should be cut off to improve the yield and quality. After the seeds are ripe in December, cut off the flower heads to dry, rub out the seeds, cut off the old stubble and cover the soil with fertilizer.

6. Pest control

Chrysanthemum cauliflower has strong resistance and special fragrance of chrysanthemum. Generally speaking, there are few diseases and insect pests. However, there is often a phenomenon of shrinkage of tender stems and leaves in production, which can be applied with calcium fertilizer or hydrated lime and organic fertilizer to improve product quality.

7. Harvest

Chrysanthemum cauliflower was harvested by stages. Usually about 35 days after the broadcast. The height of the seedlings is about 20 cm. First, the harvest is sparse. The second is to retain 12 side branches to harvest. Watering and topdressing once after harvest. Artemisia is a commodity with fresh and tender leaves. There were more than 11.5 leaves in the middle of August. The seedlings begin to harvest when they are as high as 18 centimeters. The side branches were harvested by retaining the side branches during harvest.
