摘要
研究了不同的施肥处理对高山小青菜产量和效益的影响。结果表明:N肥含量以处理T3(尿素30.0 kg/667 m2)的产量、产值、纯收益、产投比最高;P肥含量以处理T6(过磷酸钙60.0 kg/667 m2)的产值、纯收益、产投比都最高;K肥含量处理对小青菜产量、产值、纯收以对照T0(氯化钾20.0 kg/667 m2)处理最高;有机肥含量处理对小青菜产量的影响较小,但施有机肥处理比不施有机肥处理的产量和产值高;生物菌肥在小青菜上的应用效果不是很显著。
The effects of different treatment on yield and quality of Brassica chinensis were studied.The results showed that： the yield,benefit,net return and ratio of output to input of T3 was the highest（urea 30 kg/667 m2）in different N content treatment.The yield,benefit,net return and ratio of output to input of T6（Superphosphate 60.0 kg/667 m2） was the highest in different P content treatment.The yield,benefit,net return and ratio of output to input of T0（Potassium chloride 20.0 kg/667 m2） was the highest in different K content treatment.The effects of organic fertilizer on the yield and benefit was small,but the yield and benefit of the treatment applying organic fertilizer was higher than that without organic fertilizer.The effects of bacterial manure on the yield was not remarkbale.
