摘要
在皖南山区 ,香料烟 (Samsun)适宜的移栽期为 4月下旬至 5月上旬 ,栽植密度为 18～ 2 2 .5万株 /hm2 ,栽植方式以宽行密植较为适宜 ;在密度为 2 2 .5万株 /hm2 条件下 ,适宜行株距为 40cm× 10cm ,施氮量为 3 0kg/hm2 ,氮磷钾配比为 1∶2∶2～ 3。
The experiment in the effects of 5 cultural factors on Aromatic Tobacco in southern Anhui showed that the appropriate transplanting period was in the last ten days of April and the first ten days of May, plant population per hm 2 of Aromatic Tobacco was 180,000～225,000 plants, the wide-line and denser-planting were the more appropriate planting model with the condition of 225.000 plants/hm 2 and the appropriate line-plant distance was 40×10cm. And the amount of N application was 30kg/ hm 2 and N∶P 2O 5∶K 2O was equal to 1∶2∶2～3.
