Yield and Efficiency Analysis of Konjac Breeding at Different Altitudinal Cultivation Patterns in Yangxian County
In 2022,two new varieties of konjac were introduced.An interplanting demonstration with ki-wifruit,maze,jujube skin and konjac was conducted at an altitude of 1000m in Huayang town,Yangxian county,and an intercropping demonstration with maize was set in hilly area above sea level of 600m in Qishi street.The results showed a lower incidence of soft rot disease,a higher growth coefficient,increased yield,and favorable e-conomic benefits for konjac.The comprehensive benefit was also high,suitable for taro breeding in Zhongshan ar-ea.Under the condition of extreme high temperature and drought,the incidence of soft rot disease for Emoyu 1 in low altitude hilly area ranged from 15.4%to18.33%,lower than that observed in(black stems)konjac(black stems).Moreover,Emoyu 1 exhibited stronger stronger disease resistance compared to konjac.Cultivation meas-ures should be taken to reduce the disease rate,making it suitable for demonstration at low altitude.However,the incidence of soft rot disease for Konjac is 24.2%,which is unsuitable for taro breeding in hilly area.
