【摘要】 本试验采用2种不同施肥方案———复合肥方案和专用肥方案(其中专用肥中硝态N(NO3--N)含量高于复合肥中的含量),以验证不同施肥方案对烟草各指标的影响。试验表明:专用肥方案的大田长势优于复合肥方案;除中等烟比例略低于复合肥方案外,其它经济指标都优于复合肥方案;专用肥方案的化学指标也都优于复合肥方案,并且复合肥方案的上部叶烟碱偏高,接近4。可以得出专用肥方案优于复合肥方案的结论。更多还原

【Abstract】 The experiment was conducted in two different fertilizing methods to study the effect of different index of tobacco:Special fertilizer method and the compound fertilizer method,and the content of the NO3——N in special fertilizer was higher than the compound fertilizer.The study results showed:the growth,the economic index and the chemical index for tobacco fertilized special fertilizer were better than compound fertilizer’s.However,the middle-rate leaf proportion was lower than compound fertilizer’s,and the nicotine in the top tobacco leaf was high in the compound fertilizer method,nearly to 4,A conclusion that the special fertilizer method was better than the compound fertilizer’s is obtained.更多还原
