龙胆草育苗基质配方的筛选

[目的]筛选适宜龙胆草（Radix gentianae）生长的基质配方。[方法]将草炭、蛭石和旱地土按不同比例配制成龙胆草育苗基质,研究了基质的保水性能和其对龙胆草育苗性状的影响。[结果]草炭、蛭石与旱地土结合均能明显改善土壤的保水性能,有利于龙胆草出苗和生长。其中,草炭∶旱地土为6∶4与草炭∶蛭石∶旱地土为2∶3∶5的2种基质配方保水能力强,龙胆草出苗率可达80.0%以上,且由此2种基质育成的龙胆草幼苗素质显著优于旱地土壤基质。[结论]该研究为有效解决龙胆草育苗方面的难题,并为实现工厂化育苗提供了理论指导。

Screening of the Optimum Medium Formula for Radix gentianae

[Objective]The research aimed to screen the optimum medium formula for Radix gentianae. [Method]The medium formulas for Radix gentianae composed of grass peat,vermiculite and soil according to a volume ratio were selected to study the water-absorption capacity of medium and its effects on seedling characteristics of Radix gentianae. [Result]The different medium formulas added the grass peats and vermiculite could improve the water-absorption capacity and was helpful to the emergence of seedling and growth o...
