Effect of Plant Density and Base Fertilizer on The Yield and Agronomic Traits of Gentiana scabra Bge
摘要
Abstract
This study evaluated the effects of different density and base fertilizers on agronomic traits of Gentiana sca‐bra Bge .The result showed that plant density have no significantly affected on aerial part traits of Gentiana scabra Bge .The highest value of stem diameter were found in 20 plant per row treatment ,which were significantly higher than 15 plant per row treatment .Plant density have significantly affected on root length ,single root weight and plot yield ,and these values increased with an increase in plant density .The optimum plant density was 20 and 25 plant per row which could promote yield and aerial part growth .Base fertilizer could promote growth except 100g/m2 ,the value of plant heigh ,stem diameter ,leaf length and leaf width all higher than control .For root characters ,the value of root length ,single root weight ,the number of fibrous root and plot yield ,all higher than control except 100g/m2 treatment .Comprehensive analysis of agronomic traits ,the optimum applied amount of chemical fertilizer was 75g/m2 .关键词
