摘要
1988～1988年的试验结果表明,给烤烟喷施适量的硼锌稀土能促进烟株对氮、磷、钾、的吸收,协调烟叶中主要品质成分,增加烟叶产量,改善烟叶品质,提高中上等烟比例、均价和产值,而喷施猛肥则无显著的影响。
The field experimemts in 1988 and 1989 showed that spraying boron,zinc and rare earth could promote the uptake of nitrogen,phosphorus and potassium,increase yield of flue-cured tobacco and improve its quality;and that spraying manganese did not have any remarkable influence on them.
