菜籽饼肥不同用量对烤烟产量及质量的影响

Effect of application rates of rape seed cake on yield and quality of flue-cured tobacco

摘要: 试验研究了菜籽饼肥不同用量对烤烟产量和质量的影响。结果表明，施25%熟饼肥+75%复合肥的处理烤烟产量、产值最高，在施用饼肥纯N占25%以上时，随着饼肥用量的增加，烤烟产量、产值呈下降态势。饼肥用量相同时，腐熟饼肥产量、产值高于生饼肥。25%熟饼肥+75%复合肥处理的烟叶内在化学品质协调性较好，单施复合肥或单施菜籽饼肥(包括生饼和熟饼肥)都不利于烟叶内在化学品质的协调。

Abstract: An experiment was conducted to study the effect of application rate of rape seed cake on yield and quality of flue-cured tobacco.The results show that output yield and value of flue-cured tobacco are highest at 25% N from rape seed cake and 75% N from compound fertilizer.However,output yield and value of flue-cured tobacco decrease when N application rate from rape seed cake is above 25% of total applied N.With the same application amount,output yield and value of flue-cured tobacco in rotten rape seed cake treatment are higher than those in unprocessed rape seed cake.It is also observed that fluecured tobacco leaf chemical quality balances well at 25% rotten rape seed cake,plus 75% compound fertilizer treatments.At 100% rape seed cake (rotten or nprocessed rape seed cake) or 100% chemical fertilizer treatment,flue-cured tobacco leaf chemical quality becomes very unbalanced.
