摘要
目的与方法:在温室栽培条件下,用盆栽试验研究了松香甘油酯包膜尿素和不同氮浓度对烟草钾、氯等品质指标的影响。结果:松香甘油酯包膜尿素的养分释放性,在第1d低于普通尿素60.1%;处理4叶片钾含量,施松香甘油酯包膜尿素比施普通尿素上部叶片高出0.01g、中部叶片高出0.02g、下部叶片高出0.03g;处理4叶片钾/氯比,施松香甘油酯包膜尿素比施普通尿素上部叶片高出0.04g、中部叶片高出0.24g、下部叶片高出1.71g。结论:两种氮肥均有助于叶片钾和氯的积累,施松香甘油酯包膜尿素比施普通尿素的叶片钾含量有所增加。
Objective：The effect of nitrogen form of coating material as the Rosin Glycerin Este and rate of application on quality indices of flue-- cured tobacco were studied. Method：By pot culture in tobacco on the greenhouse. Result：The result shows that the early rate of nutrient released from coated- released- urea is lower 60.1% titan the early rate of nutrient released from urea; the coated - released- urea and urea all could promote the accumulation of potassium and chlorin in tobacco leaf; the Potassium content in tobacco loaves on treaanent 4, the coated - released -urea increased than that of urea and top leaves increased 0. 01g, middle leaves increased 0.02g, bottom leaves increased 0.03g;the K/CI ratio in tobacco leaves on treatment 4, the coated - released - urea increased than that of urea and top leaves increased 0.04g, middle leaves inereased 0.24g, bottom leaves increased 01.71g. Conclusion： The potassium with preference respectively on coated- released-urea increased than that of urea in tobacco leaf.
