湘西烟区新型烟草专用肥的应用效果

Optimized Special Fertilizer Effects on the Growth,Yield,and Quality of Flue-cured Tobacco

为研究新型烟草专用基肥对烤烟生长及产质量的影响,以云烟87为试验材料,分别在常德市石门县、张家界市慈利县和湘西自治州花垣县进行田间小区试验,研究了不同新型烟草专用肥对烤烟产质量及经济效益的影响。结果表明:新型烟草专用肥2号对于烟株生长发育促进作用效果最佳,可提高株高2.72%~3.24%、有效叶片数(2.16%~5.17%)和茎围(3.18%~5.75%);新型烟草专用肥3号对于协调烟叶化学品质、提升烤烟产量、中上等烟比例和均价方面效果最佳,可使烤烟产量提升3.90%~10.02%,中上等烟比例提高1.12%~4.42%。综合各项指标,新型烟草专用基肥3号更适合湘西烟区。

To study the effects of a new special base fertilizer on the growth,yield,and quality of flue-cured tobacco.Yunyan 87 was used as the experimental material to conduct field plot experiments in Shimen County of Changde City,Cili County of Zhangjiajie City,and Huayuan County of the Xiangxi Self-governing Region,to study the effects of different new special fertilizers on the yield and quality and economic traits of flue-cured tobacco.The results showed that the new tobacco special fertilizer No.2 had the best-promoting effect on the growth and development of tobacco,which could increase plant height by 2.72%-3.24%,affective leaf number,and stem circumference by 2.16%-5.17%and 3.18%-5.75%,respectively.The new to-bacco special fertilizer No.3 had the best effect on improving the chemical quality of tobacco,increasing the yield of flue-cured tobacco,the proportion of medium and superior tobacco leaves,and the average price.It could increase the yield of flue-cured tobacco by 3.90%-10.02%and the proportion of medium and superior tobacco leaf by 1.12%-4.42%.New profes-sional base fertilizer No.3 is more suitable for the Xiangxi tobacco area.
