三种肥料混施对小白菜生长、品质和经济效益的影响

Effects of Three Fertilizers Mixed on Growth,Yield and Economic Benefit in Pakchoi

以寿宁山冬乌小白菜为试验材料,研究化肥减量配施有机肥和生物菌肥对小白菜植株生长指标、品质和经济效益的影响。试验结果表明,适宜范围内的化肥减量配施有机肥和生物菌肥,虽然增加了小白菜生产成本,降低了产量,但小白菜的品质和产值增加,经济效益提高,较常规施肥增加2506.09元/667 m^2。

The study chose the pakchoi cultivar Shouning Shandongwu(Brassica campestris L.)as test material,and studied the effects of chemical fertilizer reduction and organic and bio-bacterial manure supplement on growth,yield and economic benefit of pakchoi.Within a suitable range of chemical fertilizer reduction and organic and bio-bacterial manure supplement,it made the production cost increased and the growth index and yield reduced,but it increased the quality and total production value,and it had the highest economic benefit,which was 2506.09 Yuan/667 m^2 higher than that of common fertilization treatment.
