摘要
为探究生物有机肥对林下白芨生长特性的影响,改善白芨的生长立地条件,以1年生白芨为试验材料,采用大田种植,以配施3 kg/m2的生物有机肥为处理,不加任何生物有机肥为对照,种植1年后在白芨花期4—6月观测白芨的生长生理指标及根际土壤环境.结果表明,配施3 kg/m2的生物有机肥处理能够在一定程度上促进白芨的生长发育和地上、地下部生物量积累,增加白芨叶片中叶绿素的相对含量,并有效改善根际部位土壤的理化性质.
Abstract
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.
