When selecting varieties, it can be determined according to factors such as leaf size and sawtooth edge, and it is appropriate to choose varieties with strong disease resistance, good growth ability and high yield. The late growth of chrysanthemum is directly related to the varieties, and the excellent varieties available are chrysanthemum and Artemisia stem.

2. Cultivation time

Chrysanthemum is cool and not suitable for growing in high temperature environment. The planting time should be chosen in spring and autumn. The low temperature in winter is not conducive to seed germination, but greenhouse planting can also be used. Generally, it is most suitable to sow after beginning of spring or before and after Mid-Autumn Festival.

Step 3 prepare for rotation

Chrysanthemum morifolium is a crop that can be produced all year round, so it is necessary to prepare for rotation, depending on the seasonal changes. You can plant all kinds of bean crops or some fruits and vegetables in autumn. Some green leafy vegetables are mainly planted in spring, and interplanting can be used as a sowing method.

4, soaking seeds to accelerate germination

Soak the seeds before sowing, and soak the seeds in warm water of about 35 degrees for one day and one night. Then take it out and wash it, pick out the dry, rotten and some sundries, air dry the water, and then put it at the temperature of 18 degrees to accelerate germination. More than half of the seeds are white and can be sown.

5. Soil preparation and fertilization

Chrysanthemum morifolium has strong adaptability to soil, but in order to obtain high-yield and high-quality chrysanthemum morifolium, it is advisable to choose plots with fertile soil, loose soil layer, good air permeability and soil PH value of about 6. Before sowing, apply base fertilizer and level the edge so that the base fertilizer can be fully mixed with the soil.

6, timely sowing

There are two kinds of sowing methods of Artemisia selengensis, which are generally broadcast. Before sowing, water the soil to keep moisture. When water penetrates into the soil, sowing begins. Pay attention to the planting density when sowing, and pay attention to covering the soil to preserve water and fertilizer after sowing to promote the germination and emergence of seeds.

7. Water and fertilizer management

Chrysanthemum is a water-loving vegetable. Keeping the soil moist after sowing is beneficial to the emergence of seeds, and then watering them according to the growth of plants. The nutritional demand of Chrysanthemum morifolium is relatively high, and the growth period is mainly nitrogen fertilizer. Because it is a perennial vegetable, it needs topdressing once in the later stage, but it should follow the principle of applying more and less.
