摘要
探索了油枯作基肥及烤烟复合肥不同施用时间对烟叶品质与产量的影响。结果表明,油枯与烤烟复合肥一起作为基肥施用,与只施用油枯作基肥和先用油枯作基肥、移栽后30 d施用烤烟复合肥的两种处理相比,烟叶田间长势较好,叶绿素含量、净光合速率、水分利用效率和烟叶产量与产值均高于其他两个处理,化学协调性也相对较好。
This study explored the effects of rapeseed cake as the base fertilizer and different application time of compound fertilizer on yield and quality of tobacco.The results indicated that rapeseed cake and the tobacco compound fertilizer together used as base fertilizer,compared with only rapeseed cake used as base fertilizer and the rapeseed cake used as the base fertilizer first,the tobacco compound fertilizer used after transplanting 30 d the growing situation in the field was better.The chlorophyll comparative content,net photosynthetic rate,water use efficiency,the yield and production value were also higher.The chemistry coordination was also relatively better.
