1. Land selection and preparation

Bitter chrysanthemum likes cold and cool environment, likes dampness and fertilizer, is not tolerant to drought, and is more cold-tolerant. It is suitable for planting in hillsides, forests, fields or areas near water sources at an altitude of 170m to 3200 meters. When planting, sandy loam or clay with loose soil, rich in organic matter and good water and fertility conservation can adapt to the soil pH value between 4.58.9, but the growth is best in slightly acidic soil. After selecting the land, the soil will be raked and raked flat, and combined with soil preparation, 1000-2000 kg of mature farm manure can be applied per mu according to the fertility of the soil.

2. Sowing seeds

Suitable for planting in spring or autumn, it is necessary to choose varieties with stable yield and strong disease resistance. Because the seeds of bitter chrysanthemum are small, they are sown by sowing. Open a shallow ditch on the border, spread the seeds evenly, and then cover a layer of fine soil, the soil should not be too deep, controlled between 0.5-1cm, so as not to affect the emergence of seedlings. After sowing, water should be watered once, do not trample, just suppress slightly, so as not to affect the germination rate, use about 2 kilograms of seeds per mu, and pay attention to the sowing density, so as not to affect the plant growth and the incidence of diseases and insect pests, thus affecting the yield and income.

3. Field management

Generally sowing 4-5 days after emergence, in the seedlings after breaking the soil should be timely inspection, appropriate watering to keep the soil moist, so that the soil is too dry to affect the growth of seedlings. The root system of bitter chrysanthemum seedlings is weak, so it is necessary to loosen the soil in time to promote root growth, and to avoid damage to the root system. When the seedlings grow to a certain extent, it is necessary to interseedling and replenish the seedlings in time, and once the weak seedlings are found, they should be pulled out immediately, it is also necessary to remove weeds in the field, weeds and seedlings will seize nutrients, and will also be induced to be pulled out, so they should be removed in time, and should be taken out of the field after removal to reduce the source of diseases and insect pests.

4. Fertilizer and water management

In the field management, it is necessary to reasonably water and fertilize according to the growth status of the plant to ensure its normal growth. In the seedlings, it is appropriate to keep the soil dry and wet, and not to water too much, so as to avoid excessive growth and drought, which will lead to the aging of the seedlings. In the peak season of plant growth, it is also necessary to keep the soil moist. If the water is insufficient, the bitter taste of bitter chrysanthemum is heavier and the taste is poor. When it is harvested in the late growth period, it is necessary to control the moisture and ensure the quality.
