烤烟RGH51不同施氮量试验研究

Experiment in the Different Amounts of N-fertilizer for Flue-Cured Tobacco Variety——RGH51

烤烟RGH5 1在皖南中等肥力水平田块种植 ,施化学纯氮 97.5～ 10 5 .0kg/hm2 ,N∶P2 O5∶K2 O为 1∶(1～ 1.5 )∶3 ,可获得优质适产。

The experimental result showed that flue-cured tobacco variety--RGH51 can get good quality and suitable yield in middle fertility soil when the fertilization measure of pure nitrogen:97.5～105.0kg/hm 2 and N∶P 2O 5∶K 2O=1∶(1～1.5)∶3 was applied.
