The following pro-agricultural network brings the high-yield planting techniques of chrysanthemum, let's take a look.

1. Variety selection

Artemisia annua is mainly divided into small-leaf chrysanthemum and large-leaf chrysanthemum, in which Artemisia angustifolia is more cold-resistant, strong aroma, faster growth, generally only January and a half to February can be harvested, but the yield is low. Artemisia annua L. has broad leaves, high yield, tender and short branches and good varieties, but it has the disadvantages of slow growth and late maturity.

2. Environmental factors

Artemisia annua originated in China, its adaptability is strong, has a certain cold resistance, like cool, humid environment, the suitable temperature for growth is 17-20 degrees, not resistant to high temperature, when the temperature is higher than 29 degrees, the growth is poor. The light requirement is not strict, and it can grow normally in the low light environment; the soil requirement is not strict, and the loose and fertile sandy loam soil is the best; for the loose and fertile sandy loam soil, it is only necessary to keep the soil moist during growth. but too much water will affect its growth and development. In a word, chrysanthemum chrysanthemum can be planted in all major areas of our country.

3. Cultivation techniques.

Artemisia annua can be sown from February to April in spring, from August to September in autumn and from October to November in winter. Prepare the land and make the bed before planting, select the land with deep soil layer, loose and fertile soil and convenient drainage, and mix the soil and fertilizer evenly after applying sufficient base fertilizer. Then make the border, the general width of the border is about 1.6 meters, which can be changed according to the actual situation. The soil will be fine and raked flat to sow.

Before sowing, soak the seeds to accelerate germination, soak the seeds in the greenhouse for 24 hours, and accelerate the germination in the greenhouse environment. The seeds can be sowed after budding, and the three methods of direct seeding, sowing and strip sowing can be used. The seedlings can emerge after about a week of sowing. When the seedlings grow 2-3 true leaves, the seedlings can be interspersed with a row spacing of 5-6cm, which should not be too thin or too dense. When planting, we should pay attention to fertilizer and water management, watering and fertilizing according to the weather and plant growth.

4. Control methods of diseases and insect pests
