摘要
以稻壳制备的生物炭为试验材料,以云烟87为供试烤烟品种,探究了在常规施肥基础上采用不同方式(垄面撒施、移栽穴撒施、条施、全田翻耕撒施)增施稻壳生物炭对植烟土壤改良、烟草生长发育及产质量的影响,以不施生物炭作对照,以期为生物炭在烟草种植及烟田土壤改良方面的应用提供依据。结果表明:采用不同方式施用生物炭对植烟土壤肥力和烤烟产质量均有显著影响,其中,全田翻耕撒施的效果最优,显著增加了烟田土壤的碱解氮、速效钾含量和最大田间持水量,与CK相比分别增加了23.78%、51.31%和11.54个百分点,土壤容重降低了0.16 g/cm^(3);烤后烟叶的总碱、总氮、总糖、还原糖、氯离子、糖碱比和上等烟比例显著上升。
This paper studied the effects of different application methods of rice husk biochar on soil remediation,and tobacco growth,development,yield and quality.With Yunyan 87 as the test tobacco cultivar,five treatments of rice husk biochar were set based on routine fertilization,including no biochar(CK),ridge surface broadcasting(T1),transplanting hole broadcasting(T2),groove fertlization(T3)and broadcasting after the whole field ploughing(T4).The results showed that different application methods of rice husk biochar significantly affected soil fertility and tobacco yield and quality.T4 performed the best,which significantly increased the soil alkali-hydrolyzable nitrogen and available potassium contents and maximum field water capacity by 23.78%,51.31%and 11.54 percentage points,respectively,and decreased the soil bulk density by 0.16 g/cm^(3) compared with CK;in addition,the contents of total alkali,total nitrogen,total sugars,reducing sugars and chloride ions,sugar-nicotine ratio of flue-cured tobacco and the proportion of superior tobacco increased significantly.
