摘要
以云烟87为材料,通过小区田间试验,探究了增施有机络合微肥对烤烟产量和质量的影响。试验结果表明,在常规施肥的基础上,增施有机络合微肥(6 kg/hm^2)能够促进烤烟的营养吸收和烟株生长,在移栽30 d和50 d后株高、茎围、节距和中部最大叶面积均大于对照组;B2F(上橘二)、C2F(中橘二)和X2F(下橘二)的总糖、还原糖含量下降,烟碱、钾和总氮含量提高,糖碱比和氮碱比更加协调,烟叶的内在品质得以提高;在收获期与常规施肥对比,增施有机络合微肥(6 kg/hm^2)的烤烟产量、产值以及上中等烟比例分别提高15.34、29.37和5.65个百分点,增施有机络合微肥的同时减少10%的常规施肥量,烤烟产量、产值以及上中等烟比例分别提高20.80、30.10和3.34个百分点。综合分析,有机络合微肥促进了烤烟的生长发育,提高了肥料的利用率,提升了烤烟的内在品质和经济效益,具有较好的推广应用价值。
To research the influence of the organic complexed trace fertilizer on yields and quality of flue-cured tobacco,an experiment was conducted using of the organic complexed trace fertilizer and inorganic microelement fertilizer iron in Guangyuan city,Sichuan province.The results indicated that on the basis of conventional fertilizers,the organic complexed trace fertilizer facilitated the nutrient absorption and the growth of the tobacco.and increased the plant height,the stem circle,the pitch of the stem and the largest leaf area raised after 30 and 50 days of the transplant.in In the levels of B2F,C2F and X2F,the total sugar and the reducing sugar decreased,nicotine,potassium and total nitrogen raised,as well as the ratio of sugar to alkali and the ratio of nitrogen to alkali were more coordinated more,the inner quality of tobacco was overally improved.With the application of organic complexed trace fertilizer,the yield,output value and the proportion of high quality tobacco had increased by 15.34%,29.37% and 5.65%,respectively.When reducing the conventional fertilization by 10%,the yield,output value and the proportion of high quality tobacco increased by 20.80%,30.10% and 3.34%.As a result,the organic complexed trace fertilizer facilitated the growth of the tobacco,improved the utilization of the conventional fertilizer as well as enhanced the economic benefit of the flue-cured tobacco,it turned out to have a high promotion application value.
