(1) seed selection: it is best to select some seeds with glossy appearance, no damage on the surface, no disease and strong disease resistance.

(2) sowing time: spring or autumn.

(3) sowing method: sow the seeds evenly into the dug ditch, then spread a layer of thin soil, and finally pour appropriate amount of water. When sowing, sow it in the middle of the ditch as far as possible to avoid unstable root length.

(4) sowing density: about 2 kilograms of seeds are used in an mu of land, depending on where you plant it. If you plant it on a hillside, it may be less.

The main results are as follows: (1) Water requirement: after the seeds emerge, a small amount of water should be properly irrigated to keep the soil moist, and in the peak growth period, the amount of watering and watering times should be determined according to the degree of dryness and wetness of the soil, and then the watering should be reduced in the later stage of growth.

(2) Fertilizer requirements: during the growth of seedlings, an appropriate amount of mature manure can be applied according to the growth of bitter chrysanthemum, and about 1000 kg of mature manure can be applied per mu of land with normal fertility.

(3) Seedling supplement: when the seedlings grow to a certain extent, the overdense seedlings should be transplanted to the place where there are no seedlings in time to ensure their uniform growth, and the weak and diseased seedlings can be pulled out in time.

(4) ploughing and loosening the soil: when the seedlings grow to a certain extent, the soil should be loosened according to the soil conditions, and the weeds in the garden can be removed to prevent nutrients from being absorbed. When loosening the soil, it must be gently, so as not to damage the root system.
