| 摘 要： | 通过在烤烟苗期的不同时期喷施稀土,研究了稀土对培育烤烟健壮苗和烟草产量、质量的影响。试验结果表明:在小十字期喷施稀土时苗期的烟苗素质和生长势最优,但在猫耳期喷施稀土的烟株在大田的长势及经济性状表现最佳,产量2181.3 kg/hm2,比对照增产了7.74%;产值27528元/hm2,比对照增值了9.54%;上等烟比例21.86%,比对照增加了2.91个百分点。建议烤烟生产上以猫耳期喷施稀土为宜。 |

| Abstract: | The effects of rare earth application on the breeding of seedlings,the yield and quality of flue-cured tobacco were investigated by spraying rare earth at different stages of tobacco seedling.The results showed that rare earth application at two true leaves stage could improve the quality and growth potential of tobacco seedlings.When rare earth was applied at the stage of true leaves as cat s ear,the best growth and economic characters performance of tobacco plants in the field could be gotten,and the yiel... |
