为在丽江烟区进一步明确有机-无机复合肥对烤烟产质量的影响研究,进行了有机-无机复合肥配施试验:A.底肥、追肥均为烤烟专用有机-无机复合肥;B.底肥为烤烟专用有机-无机复合肥,追肥为烤烟专用无机肥:C.底肥、追肥均为烤烟专用无机肥(CK)的3个处理对烤烟生长及产量、品质的影响。结果表明:底肥、追肥均为烤烟专用有机-无机复合肥和底肥为烤烟专用有机-无机复合肥,追肥为烤烟专用无机肥产量分别比底肥、追肥均为烤烟专用无机肥(CK)高34.3%,20.4%;产值分别比CK高24.7%,47.8%;中上等烟比例分别比CK增加8.9%和19.3%。适量的有机-无机复合肥与烤烟复合肥配合施用,效果明显优于单纯施用烤烟复合肥,它不仅可以促进烟株生长发育,增强抗病性,而且对烟叶产量、吸食品质、经济效益都有较大幅度提高。
In order to further clarify the effect of organic-inorganic compound fertilizers on the yield and quality of flue-cured tobacco in Lijiang tobacco-growing areas, the organic-inorganic compound fertilizers were applied to test: A. The base fertilizer and top dressing were all organic-inorganic compound fertilizers for flue-cured tobacco; Flue-cured tobacco for organic-inorganic compound fertilizer, top dressing for flue-cured tobacco: C. Base fertilizer, top-dressing are flue-cured tobacco for the three inorganic fertilizer (CK) on the growth, yield and quality of flue-cured tobacco. The results showed that both base fertilizer and topdressing fertilizer were organic-inorganic compound fertilizer for flue-cured tobacco and organic-inorganic compound fertilizer with base fertilizer as flue-cured tobacco. The yield of special inorganic fertilizer for flue-cured tobacco topdressing was 34.3% , 20.4% respectively. The output value was 24.7% and 47.8% higher than that of CK respectively. The proportion of middle-high grade tobacco increased by 8.9% and 19.3% respectively compared with that of CK. Appropriate amount of organic-inorganic compound fertilizer and flue-cured tobacco compound fertilizer with the effect is obviously better than the simple application of flue-cured tobacco compound fertilizer, which not only can promote tobacco growth and enhance disease resistance, but also on the yield of tobacco, smoking quality, economic benefits More substantial increase.
