摘要
采用随机区组设计,研究不同基追肥比例对云烟87烤后烟叶经济性状、化学成分和评吸质量的影响,为贵州省春旱烟区合理施肥提供依据。结果表明:在大田施肥量不变的条件下,随着追肥比例的增加,云烟87烤后烟叶的产量、产值、均价、上等烟率随之提高,T4(基追比7:3)表现最好,产量较其他处理高269.3~515.3 kg/hm^2,均价较其他处理高0.6~1.3元/kg;化学成分及协调性综合评价下部叶T1(不追肥)表现相对较好,中、上部叶T4表现相对较好;评吸质量随追肥比例的增加总体差异不大,以T2(基追比9:1)、T4表现略好。总体来看,在本试验范围内,基追比为7:3时更有利于春旱烟区云烟87产量和质量的提高。
A randomized block was desiged to study the effect of different base and topdressing fertilizer ratio on the economic characteristics,chemical composition and smoking quality of Yunyan 87 roasted,providing a basis for rational fertilization in the tobacco area of spring drought in,Guizhou The results showed that the yield,output value,average price and superior tobacco rate of the flue-cured tobacco leaves of Yunyan 87 increased accordingly with the increase of the proportion of fertilization under the condition of constant field fertilization.Production of T4(base-topdressing ratio of 7:3)was 269.3~515.3 kg/hm^2 higher than other treatments,which performed the best,and the average price was 0.6~1.3 Yuan/kg higher than other treatments.The comprehensive evaluation of chemical composition and coordination of the lower leaf T1(no topdressing)performance was relatively good,as well as the middle and upper leaves of T4.The overall difference in evaluation quality was not significant,with the increase of the proportion of topdressing fertilizer,and the overall performance of T2(base-topdressing ratio of 9:1)and T4 was slightly better in terms.Overall,in this test,the basal-topdressing ratio of 7:3 is more conducive to yield and quality improvement of Yunyan 87 in the spring drought tobacco area.
