| 摘 要： | 采用漂浮育苗方式研究了保水剂与珍珠岩配比基质对烟苗出苗率和生长的影响,为新型烤烟育苗基质在生产实际中的示范和应用推广奠定理论基础。试验结果表明,在保水剂中添加30%的珍珠岩的新型烤烟育苗基质与普通基质相比,出苗率持平,烟苗前期的生育期进程提前,成苗期提早0～2 d,获得持平或更高的农学性状及干物质重,叶绿素含量增加0.24 mg/g,根系硝酸还原酶和超氧化物歧化酶分别增加1.73μg/g.h和31.3μg/g.h。保水剂中添加30%的珍珠岩配制的新型烤烟育苗基质可以替代以草炭、泥炭为主的常规基质。 |

| Abstract: | The experiments were carried out to study the effects of application of mixed water retention agent and pearlite on the emergence rate and the growths of flue-cured tobacco seedlings by the floating system and to provide a theoretical base for the new seedling medium.The results showed that: compared with peat medium,application of mixed water retention agent and 30% pearlite could had the same emergence rate and reduced the growth period by 0~2 d,thus having a higher or the same effects on agronomic charac... |
