箭舌豌豆翻压配施微生物菌剂对连作烟田烤烟种植的增产提质效应OA

To determine the effect of Vicia sativa L.incorporation combined with microbial inoculant application in a continuous cropping tobacco field,a field experiment was conducted for'Xiangyan 7'with five treatments:no planting of V.sativa+conventional fertilization(CK),V.sativa incorporation+conventional fertilization(T1),V.sativa incorporation+conventional fertilization+microbial inoculant application(T2),V.sativa incorporation+15%reduction of conventional fertilization+microbial inoculant application(T3),and V.sativa incorporation+15%reduction of conventional fertilization(T4).The effect of the different treatments on the growth,disease resistance,leaf quality,and economic performance of flue-cured tobacco was evaluated.The results indicated that compared with CK,T2 significantly promoted the growth of tobacco plants,significantly increasing the plant height,stem circumference,and number of effective leaves.Compared with CK,T1 to T4 significantly decreased the disease rate and mortality rate,improved the balance of chemical components,and significantly increased the yield,output value,proportion of top-grade leaves,and average price.Particularly,T2 demonstrated the best performance,with a disease rate of 21.43%,a proportion of top-grade leaves being 47.87%,and a yield of 2 495.42 kg/hm2.In conclusion,V.sativa incorporation combined with microbial inoculant application could alleviate the continuous cropping obstacles in tobacco fields,being suitable to be promoted in continuous cropping tobacco fields of Western Hunan and similar ecological zones.
