| 摘 要： | 为蚯蚓肥基质在生产实际中的示范和应用推广提供理论依据,采用漂浮育苗方式研究了蚯蚓肥与珍珠岩配比基质对烟苗根系生长与生理特征的影响.结果表明:1) 与常规基质相比,蚯蚓肥添加30%的珍珠岩混配处理的出苗率持平,随着蚯蚓肥比例的增加,出苗率显著降低.2) 蚯蚓肥添加30%珍珠岩混配处理的地下部干物重和地上部干物重显著高于常...

| Abstract: | The experiments were carried out to study the effects of application of mixed vermicompost and pearlite on root development and physiological features of flue-cured tobacco seedlings by the floating system and to provide a theoretical basis for the new seedling medium.The results showed that compared with peat medium,application of mixed vermicompost and 30% pearlite could had the same emergence rate.However,the emergence rate would decrease if the percentage of vermicompost exceeded 70%,respectively.The dr... |
