基施水溶肥对油白菜生长及经济效益的影响

Effect of Water-Solubility Fertilizer on Growth and Economic Benefit of Brassica chinensis

为分析水溶肥作为基肥对油白菜生长和产量的影响,对武威清源镇井水灌溉区的油白菜进行施肥试验。结果表明,基施水溶肥(含Ca+Mg)可改善油白菜的株高、开展度、莲座直径、单株叶片数、叶片性状和叶绿色等性状,较空白对照组可增产108.1%,较常规施肥可增产12.1%,肥料投入产值比为1:23.3,且施肥经济效益明显。研究结果可为基施水溶性肥对其他作物增产增效提供理论指导。

In order to analyze effect of water-solubility fertilizer as base fertilizer on growth and yield of Brassica chinensis,a fertilization experiment was conducted in well water irrigation area of Qingyuan town,Wuwei.Results showed that basal application of water-solubility fertilizer(including Ca + Mg) could improve plant height,development degree,rosette diameter,leaf number per plant,leaf traits and leaf green of Brassica chinensis.Compared with blank control group,it could increase the yield by108.1%,12.1% and ratio of fertilizer input to output value was 1 ∶ 23.3.It could provide theoretical guidance for basic application of water-solubility fertilizer on yield and efficiency of other crops.
