Embodiment 1
[0020] Example 1 A method for breeding Artemisia annua heavy ion beam irradiation, comprising the following steps:
[0021] (1) The seeds of Artemisia annua with high artemisinin content, large leaves and good plant shape were collected in Yongzhou, Hunan, and the imported seeds were planted in the field of Yuzhou, Henan. The results showed that the disease resistance, yield, and artemisinin content of this variety were better than those of the local planting varieties. According to the plant type and growth performance of individual plants in the field, bad individual plants were eliminated, good individual plants were retained, and seeds with full grains were selected to be used as heavy ion beam irradiation breeding materials.
[0022] ⑵ Using the National Laboratory Lanzhou Heavy Ion Accelerator, using a heavy ion beam with an energy of 80 MeV / u and a linear energy transfer density LE T=28.12 keV / μm 20 Ne 10+ , with an irradiation dose of 10-20 Gy and a dose rate of 2 Gy...

According to the plant type and growth performance of individual plants in the field, bad individual plants were eliminated, good individual plants were retained, and seeds with full grains were selected to be used as heavy ion beam irradiation breeding materials.
[0029] ⑵Using the National Laboratory Lanzhou Heavy Ion Accelerator, using a heavy ion beam with an energy of 120 MeV / u and a linear energy transfer density LET=28.12 keV / μm 12 C 6+ , with an irradiation dose of 60-80 Gy and a dose rate of 10 Gy / m...
Embodiment 3
[0034] Example 3 A method for breeding Artemisia annua heavy ion beam irradiation, comprising the following steps:
[0035] (1) The seeds of Artemisia annua with high artemisinin content, large leaves and good plant shape were collected in Yongzhou, Hunan, and the imported seeds were planted in the field of Yuzhou, Henan. The results showed that the disease resistance, yield, and artemisinin content of this variety were better than those of the local planting varieties. According to the plant type and growth performance of individual plants in the field, bad individual plants were eliminated, good individual plants were retained, and seeds with full grains were selected to be used as heavy ion beam irradiation breeding materials.
[0036] ⑵ Using the National Laboratory Lanzhou Heavy Ion Accelerator, using a heavy ion beam with an energy of 100 MeV / u and a linear energy transfer density of LET=28.12 keV / μm 16 o 8+ , with an irradiation dose of 20-60 Gy and a dose rate of 6 G...
