种植方式对工业大麻产量相关性状的影响OA

The planting methods of industrial hemp for different purposes are different,and the differences in planting methods can be reflected in the planting density.In this study,correlation analysis and principal component analysis were used to analyze 10 yield related traits of three industrial hemp varieties under two planting methods.The results showed that planting method was extremely significantly negatively correlated with plant height,stem thickness,number of nodes,fresh stem weight and dry stem weight,significantly negatively correlated with dry skin weight,and significantly positively correlated with internode length.Principal component analysis of yield related traits extracted 2 principal components with a cumulative contribution rate of 86.043%,from which 4 yield key traits were screened.The introduction resource and Hanma 10 were suitable for both seed and fiber planting(250 seeds/m2,row spacing was 30 cm),while Hanma 12 was suitable for fiber planting(450 seeds/m2,row spacing was 15 cm).
