The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
