不同基追肥比例及施氮量对紫色土旱地烤烟产质量的影响OA北大核心CSCDCSTPCD
Effects of different ratio between base and topdressing N-fertilizers and N application rates on yield and quality of tobacco leaves in dry land of purple soil
采用随机区组小区试验研究了不同基追肥比例及施氮量对赣南紫色土旱地烤烟产质量的影响。结果表明，在施氮量为135 kg/hm2、基追肥比例为40%：60%（处理 N135-4-6）和50%：50%（处理 N135-5-5）条件下，烟株株高、茎围、有效叶、单叶重等农艺性状及烟叶产质量均优于基追肥比例为60%：40%（处理 N135-6-4）。在施氮量为120 kg/hm2、基追肥比例为40%：60%（处理 N120-4-6）下，烟株生长状况及烟叶产…查看全部>>
Effects of different ratio between base and topdressing and N application rates on yield and quality of tobacco leaf were investigated by randomized block experiment in dry-land purple soil. Results showed that significant differences existed in plant height, stem diameter, effective leaf number, single leaf weight and yield and quality of tobacco leaf under N135-4-6 and N135-5-5 treatments compared with N135-6-4 treatment. Tobacco grew worse and yield and q…查看全部>>
