摘要
在中上肥力的黄泥田上 ,通过田间试验研究了 5种烤烟专用肥对烤烟生长发育及产量和品质的影响。结果表明 ,在专用肥氮磷钾用量等于或低于单元化肥配施的条件下 ,施用专用肥的处理均能增加烤烟的株高、茎围、叶面积和单叶重 ,不同程度地提高烟叶产量和外观品质 ,但烟叶化学成分未见有明显改善。与单元化肥配施相比 ,施用自配烤烟专用肥 0 1 -2号、0 0 -1号和郴州烤烟专用肥的处理烟叶上等烟比例分别提高1 2 .3 3、9.5 5、9.2 3个百分点 ,均价每kg分别增加 1 .9元、2 .0 1元和 1 .3 5元 ,产值分别增加了 70 .2 2 %、63 .84%和 44.46% ,差异均达显著或极显著水平。施用专用肥的处理 ,烟叶产量均高于单元化肥配施 ,但差异不显著。从综合效果看 ,本试验条件下以自配烤烟专用肥 0 1 -2号最佳 ,0 0 -1号次之 ,再次为郴州烤烟专用肥。
A field trial was conducted in a loess field with an average or above fertility level to study the effects of 5 different specific fertilizers on growth, yield and quality of flue-cured tobacco. The results showed as follows: when the applied amount of N, P and K were same to or even lower than that of the fertilizer compounds, specific fertilizers for flue-cured tobacco could benefit its agricultural properties and improve its yield and quality, but the content of chemical composition of tobacco leaves wasn’t improved obviously. Compared with the contrast treatment, the treatments of specific fertilizers such as 01-2, 00-1 and Chenzhou could improve the production value by 70.22%, 63.84% and 44.46%, respectively; the proportion of the best grade tobacco of the three treatments, were increased by 12.33%, 9.55% and 9.23% respectively. Besides, the difference in the quality index between the treatments of specific fertilizer and the fertilizer compounds was remarkable. However, the yield difference between them wasn’t evident. In view of the results of all the checked index, the 01-2 specific fertilizer was the best, the next was the 00-1, and the third is the Chenzhou.
