【摘要】 为研究有机肥、化肥及其配施对生菜产量及品质、效益的影响,在相同肥料成本的基础上,设无肥、NPK化肥、商品有机肥、有机—无机肥配施4个处理。试验结果表明,生菜施用化肥、有机肥及有机-无机配施均能获得显著的增产效应;有机—无机肥料配合施用,比单施化肥增产16.85%,比单施有机肥增产82.87%;单施化肥处理的生菜硝酸盐含量比单施有机肥处理的高9.59倍,比有机—无机配施处理高4.3倍;有机—无机配施处理还能促进生菜对氮、磷、钾养分的吸收,养分利用率提高23%(绝对值)。

【Abstract】 In order to study the effects of organic manure,chemical fertilizer application and their cooperation on yield and quality of lettuce,four treatment were established,which are:no fertilizer,NPK chemical fertilizer,commercial organic manure and chemical cooperation at same cost level.The results showed that the lettuce yield was increased by applying organic manure or chemical fertilizer,but chemical fertilizer cooperated with organic manure gave higher yield than the other treatments,which could increase 16.85% and 82.87% yield than the treatments chemical fertilizer and organic manure,respectively.The lettuce nitrate content in chemical fertilizer treatment was 9.59 and 4.3 times higher than that in the organic manure and chemical cooperated with organic manure treatment.The lettuce fertilized with chemical fertilizer and cooperated with organic manure could promote N,P,K absorption,which raise 23% utilization rate of nutrient.
