The Effect of Bioorganic Fertilizer on the Growth Characteristics of Bletilla striata Under Forests
In order to investigate the effect of bioorganic fertilizer on the growth characteristics of underground Bletilla striata and improve the growth site conditions of Bletilla striata, annual Bletilla striata was used as the experimental material and planted in the field, with a combina-tion of 3 kg/m2 bioorganic fertilizer as the treatment and no bioorganic fertilizer as the control.After planting for one year, the growth physio-logical indicators and rhizosphere soil environment of Bletilla striata were observed from April to June during its flowering period.The results showed that the application of 3 kg/m2 bioorganic fertilizer treatment can promote the growth and development of Bletilla striata,as well as the accumulation of aboveground and underground biomass, increase the relative content of chlorophyll in Bletilla striata leaves, and effectively improve the physicochemical properties of the rhizosphere soil.
