肥料种类与配比对烤烟生长发育及产量品质的影响

为了弄清在湘南生态条件下不同肥料种类配比对烤烟生长发育及产量，品质的影响，为烤烟优质适产提供科学施肥的依据，１９９２年和１９９３年进行了共７个处理的田间肥料试验。结果表明，施用等量氮，磷，钾含量的肥料，由于肥料种类和配比不同，对烤烟生长发育及产量品质的显著不同。

THE EFFECTS OF FERTILIZER CLASSES AND RATIO ON GROWTH,YIELD AND QUALITY IN FLUE CURED TOBACCO

An on farm test was conducted in the south of Hunan province in 1992 and 1993. The results showed that:the differences in the characteristics of flue cured tobacco (Nicotiana tabacum L.) grown under various nutrition conditions caused by applying different classes and ratio of fertilizers were significant,although the applied amount and timing of fertilizers were same. Application of adequate amounts of the proper nutrients is necessary for profitable tobacco production. For the soils of average fertilization fertilizer rates were proposed as follows:Approximately 150 kg of nitrogen per hm 2 are adequate for most of the soils. About 15 percent of total nitrogen amount should be in the form of farm manure. Among them 750 kg/hm 2 cake fertilizer were obtained from the mixed fertilizer.
