The cultivation and quality comparison of Hongwu hybrid Gastrodia elata Blvme.at different altitudes
The commercial Hongwu hybrid Gastrodia elata Blvme.and seeds were cultivated at 1 800 m above sea level,and the corre-lation of agronomic characters of Hongwu hybrid Gastrodia elata Blvme.was analyzed.The commercial Hongwu hybrid Gastrodia elata Blvme.was cultivated at 1 800 m and 500 m above sea level,and the yield and correlation analysis were carried out.The results showed that when Hongwu hybrid Gastrodia elata Blvme.was cultivated at an altitude of 1 800 m,the quantity was small,and the indi-vidual weight and the yield were high.There was a significant positive correlation between individual weight and tuber length and tuber shape index.Compared with 500 m above sea level,the fresh weight,dry weight,p-hydroxybenzyl alcohol content,gastrodin and p-hydroxybenzyl alcohol content of a single tuber were significantly higher at 1 800 m above sea level.When cultivating Hongwu hybrid Gastrodia elata Blvme.seeds,the quantity,yield,market price and cultivation benefit of seeds were higher.
