采用田间随机区组试验,在相同施氮量的条件下,以当地常规施肥作对照,分别对大田生长烟叶单独施用不同梯度用量的豆饼、发酵饼肥,对烟叶进行农艺性状、经济性状、化学成分检测以及感官质量评吸.结果表明:随着豆饼、发酵饼肥施用比例的逐渐增加,烟叶有效叶数增多、叶面积增大,烟叶产量增加,内在质量得到改善.

应用康寿2号营养液、普利登、肥万钾叶面肥对烤烟NC55品种喷施试验,结果表明:3种叶面肥均能显著促进烟株的生长发育,提高烟叶的产量和产值,其综合效果为肥万钾＞普利登＞康寿2号营养液;提高烟叶的产量分别为264.50、299.15、278.52 kg/hm2;提高烟叶的产值分别为7 793.78、8 098.04、8 396.62元/hm2.施用叶面肥处理还原糖、总糖增加,两糖差好于对照,烟叶含钾量增加明显.

To search for substitutes of chemical fertilizers and chemical pesticides in the production of strong flavor type tobacco, biogas slurry was applied in Zhu Cheng. An Qiu and Gao Mi. The results showed that biogas slurry can promote the growth of tobacco seedlings, enhance the stem height, stem diameter and root weight. The biogas slurry also can improve the agronomic characters of tobacco. The yield, market value, average price and proportion of superior tobacco were increased by 4.02%, 8.59%, 4.38% and 8.15% respectively by biogas slurry application compared with the control. The appearance quality of tobacco however, was not changed. Biogas slurry showed good control effect on Myzus persicae as well as tobacco virus disease, black shank and brown spot, with the incidence rates of the 3 diseases were reduced by 59.96%, 55.56% and 19.05% respectively. In conclusion, biogas slurry can promote the growth of tobacco, control tobacco diseases and pests, and improve tobacco quality.
