摘　　要：为探究菽麻秸秆有机肥对烤烟农艺性状、产质量及根结线虫病的影响,在四川攀枝花烟区开展了3种用量(15、30、45 kg/667m^(2))的菽麻秸秆有机肥防治烟草根结线虫病的田间试验。结果表明,增施菽麻秸秆有机肥能够有效改善烤烟的农艺性状,提高烤烟的产量、产值和均价,其中以30 kg/667 m^(2)菽麻秸秆有机肥处理的农艺性状、产质量的综合表现最好,产量、产值、均价较0.5%阿维菌素处理分别增加了224.18 kg/hm^(2)、17316.6元/hm^(2)和5.22元/kg,肥料投入产出比为1∶11.12,160 d的平均相对防效高达62.77%,比阿维菌素防效高12.86%。建议攀枝花烟区,菽麻秸秆有机肥宜在烤烟移栽期施用1次,施用量30 kg/667m^(2)。In order to understand the effect of C.junce L.straw organic fertilizer on the agronomic characters,yield and quality of flue-cured tobacco and root-knot nematodes,a field experiment was conducted with three different dosages(15,30,45 kg/667m^(2))of C.junce L.straw organic fertilizer to study its effect on tobacco root-knot nematode disease in Panzhihua,Sichuan province.The results showed that adding C.junce L.organic fertilizer effectively improved the agronomic traits,and increased the yield,output value and average price of flue-cured tobacco.The comprehensive performance of agronomic traits,yield and quality of flue-cured tobacco was the best under treatment of C.junce L.straw organic fertilizer(30 kg/667m^(2)).Compared with 0.5%abamectin treatment,the yield,output value and average price increased by 224.18 kg/hm^(2),17316.67 yuan/hm^(2)and 5.22 yuan/kg,fertilizer input-output ratio was 1∶11.12,respectively.The average relative control effect of 160 days was up to 62.77%,12.86%higher than abamectin treatment.Therefore,the recommended method organic fertilizer in Panzhihua tobacco area was 30 kg/667m^(2)organic fertilizer one time when the flue-cured tobacco was transplanted.
