2. The annual growth period of gentian is about 180 to 210 days. Under natural conditions, gentian blossoms in early August, the flowering period is longer, it opens down from the top of inflorescence, the seeds are gradually mature, and the mature seeds are scattered from the crack at the tip of the capsule.

What are the prevention and control techniques of gentian diseases and insect pests?

Gentian spot blight: mainly harms the leaves and, in serious cases, causes the whole leaf to die. 1000 times of carbendazim can be used and sprayed every 10 days after summer, the effect is better. And remove the dead branches and leaves in the field before winter and burn them to prevent the spread of germs.

2. Insect pests

The serious harm of mole cricket and grub can be used for soil disinfection during soil preparation and prevention and control during the growth period. Soil disinfection can apply 35% endosulfan 0.5-1.5 kg per mu, or phoxim 0.5 kg per mu, mixed in the border soil; mole cricket can be trapped and killed by black light during the growth period.

4. timely topdressing: foliar topdressing was carried out after transplanting slow seedlings, and foliar topdressing could be carried out twice from leaf expansion to budding and from flowering to fruiting, and foliar fertilizers such as potassium dihydrogen phosphate, Yemanbao and high yield were used.

5. Thinning flowers and picking buds: in order to reduce the consumption of nutrients, promote the accumulation of root matter, accelerate the growth of rhizomes and improve the cultivation efficiency, the buds should be removed completely after budding in non-harvested fields.
