摘要
针对烟农一味地追求高产,过量施用氮肥而造成烟叶化学成份失调,烟碱含量偏高,从而导致烟叶杂气增多,品质下降的现象,对优良新品种“延晒五号”进行最佳氮、磷、钾肥施肥量试验.结果表明,氮、磷、钾肥的最佳施肥量分别为140,70,140 kg/hm2.
The optimum fertilizing quantity trial of N, P, K to the good new variety 'Yanshai5' was researched in viewed of the devoting exclusive attention to output which resulted in the imbalance of chemical components of tobacco leaves, high content of nicotine, higher amount of assorted smoke and declination of quality. The results showed that the best fertilizing quantities of N, P, K were 140, 70, 140 kg/km^2 respectively.
