1. Growth habits

The mackerel likes to grow in a warm, humid and sunny environment, and it also has certain requirements for the soil, which is loose, fertile, moist and well drained. It is best to go through ploughing for many times before planting to make the soil fully weathered, and then in the last ploughing, according to the fertility of the soil, applying rotten farm manure or organic fertilizer as base fertilizer can improve sufficient nutrients for plant growth, shaping and raking flat after fertilization, ready to sow.

2. Sowing seeds

The seed is an annual or biennial herb, so it can be planted in both spring and autumn, but when the best sowing time is from September to November in autumn, when the seed is sown within the breaking time, the seed has the highest germination rate and the best growth. When sowing, the seeds with good varieties and full grains can be selected by hole sowing or strip sowing. Hole sowing should be made according to the row spacing of 20 × 40 cm on the border surface, sowing several seeds in each hole, covering the soil and watering. Strip sowing in the border surface according to the row spacing of 40 cm to open a shallow ditch, the seeds will be evenly scattered into the ditch, the same soil can be watered.

3. Field management

Generally, seedlings can emerge after sowing for 20-30 days. Weeds should be weeded in time before emergence so as not to affect the growth of seedlings. In addition, weeding should be combined with weeding and replenishing seedlings at 11-12:00. Leave 4-5 strong seedlings in each hole, weak seedlings and diseased seedlings should be removed in time, after overwintering, combined with ploughing and weeding in February of the following year, topdressing once, it is appropriate to use human feces and urine. In the later stage, according to the different growth stages of the plant, topdressing 1-2 times to promote the robust growth of the plant and increase the yield.

4. Diseases and insect pests

Sclerotinia sclerotiorum is a common disease in cultivation. It is a fungal disease, which can be infected from seedling stage and adult plant, mainly harming stems and fruits. Field management should be strengthened in prevention and control, garden cleaning should be done well in winter, overwintering bacteria sources should be eliminated, varieties with strong disease resistance should be selected when planting, mixed powder of plant ash and cooked lime should be applied around the root system, or chemical control should be sprayed around the root system.
