Cultivation of Artemisia annua: how can Artemisia annua be planted with high yield?

How can planting Artemisia annua L. produce high yield? Please introduce the method of chrysanthemum chrysanthemum with short growth period, few diseases and insect pests, wide cultivation season, very simple management and no need for intermediate ploughing, weeding, topdressing and other measures under the condition of sufficient base fertilizer. Just pay attention to the following five points: 1. Before sowing, it is best to soak the seeds in warm water of 35 ℃ ~ 40 ℃ for 5 hours, and then accelerate germination under the condition of 2 ℃ ~ 25 ℃. When the seeds are white, you can sow or strip sow. 2. The sowing rate of Artemisia annua is too small, which not only grows slowly, but also has many lower leaves, so it is difficult to achieve the ideal height and yield. If the sowing rate is too large, the young stem is thin and weak, and the lower leaves are easy to yellowing or rotten seedlings. 3. The temperature in solar greenhouse or greenhouse should be controlled below 35 ℃. If the temperature is too high, it should be properly ventilated and cooled down, and the appropriate temperature should be 25 ℃ ~ 30 ℃. This can not only ensure rapid growth, but also ensure product quality. 4. water management during the growth period is very important, lack of water and drought, plant stems and leaves are easy to harden, reduce yield, poor quality, according to the soil dry and wet situation, timely and appropriate amount of watering, but not too much watering, so as to avoid rotting roots. 5. To timely harvest, generally 30-40 days after emergence, seedling height of 25-30 cm can be harvested. Too late harvest will affect the yield and quality and the normal growth of high-planted varieties in the greenhouse. Generally, the yield per mu is 1000-1500 kg, and the benefit is considerable.
