连续3年在4种植烟红壤(酸性、微酸性、微碱性和碱性)上,烤烟移栽前适量单施化肥、大量单施化肥、适量化肥增施小麦秆、玉米秆和有机土壤改良剂、菜籽饼配施化肥,研究施用有机物对烤烟产量、产值及烟叶品质的影响。结果表明:烤烟移栽前增施小麦秸秆(田烟:7500kg/hm2,地烟:6000kg/hm2),极显著地增加烟叶产值;评吸综合得分最高;对烤烟产量和烟叶化学品质无明显影响。
For 3 years in succession, four kinds of tobacco-growing red soils (acidic, slightly acidic, slightly alkaline and alkaline) had been planted for a long time. Single fertilizers were applied before flue-cured tobacco was transplanted in a large amount. Fertilizers were applied in large amounts and wheat straw, corn stalks and organic soils Agent and rapeseed cake with chemical fertilizers to study the effects of applying organic compounds on the yield and yield of flue-cured tobacco and the quality of tobacco leaves. The results showed that the application of wheat straw (flue-cured tobacco: 7500kg / hm2, ground tobacco: 6000kg / hm2) before flue-cured tobacco transplanting increased the output of flue-cured tobacco significantly, and the highest comprehensive score of flue-cured tobacco had no significant effect on the yield of tobacco and the chemical quality of tobacco .
