Daqianqiliuguan is an excellent shrub host of the genus Iris which has been screened in recent years. It has natural distribution in Yunnan, Guangxi, Guangdong, Fujian, Sichuan, Guizhou, Hunan and Jiangxi provinces in our country. It has fast-growing, two years of cultivation can put the plastic use, resistance to infertile drought, adaptability, good production of shellac, light color, winter seed preservation effect is good, germination and renew ability, can be used repeatedly and other excellent traits, Has been promoting the cultivation of shellac production in China.

Pods soon after the burst burst, seed must be promptly collected. Seed collection at different times, the seed yield and seed thousand grain weight is also different, from October to November harvest more full of seeds, the seed rate was 29%, grain weight 14 grams.
