摘要
采用大田试验,研究了氮肥增效剂配合不同用量氮肥对烤烟农艺性状、产量、经济效益及烟叶品质的影响。结果表明,氮肥增效剂与80%~100%常规用量氮肥配施,能促进烤烟团棵期和成熟期的生长发育,又能提高烟叶产量、经济效益和烟叶的品质,其中以常规施肥配施氮肥增效剂效果最佳。综合表明,氮肥增效剂在烟草生产中有较大的推广意义。
A field experiment was conducted to study the effects of combined application of three different amounts of nitrogen with nitrogen fertilizer synergist on agronomic trait,economic benefit and leaf quality of tobacco.The results indicated that combined application of nitrogen fertilizer synergist with 80%～100% normal amount of nitrogen could promote growth of tobacco plant at resetting stage and maturing stage,and it also can improve yield,economic benefit and quality of tobacco leaves,among which combined application of normal fertilizer rate with nitrogen fertilizer synergist had the best effect.Therefore,the nitrogen fertilizer synergist has significance for extending application of nitrogen fertilizer synergist in the tobacco production.
