不同肥料对矮脚奶白菜产量及养分吸收效果的影响

Effects of different fertilizers on the yield and nutrient absorption of Brassica campestris L.

施用不同肥料种植矮脚奶白菜的田间试验结果表明,与不施肥的对照相比,有机无机混合肥增产效果最为显著,比不施肥对照增产188%;检测矮脚奶白菜植株N、P2O5、K2O含量结果表明,蔬菜专用肥促进植株吸收养分的能力显著高于其他肥料,植株每667 m2吸收N 4.05 kg、P2O5 1.85 kg、K2O 8.55 kg;分析奶白菜收获后3种肥料处理对土壤养分含量的影响结果发现,单独施用有机肥处理显著增加土壤中各种养分含量,并提高土壤pH水平。

Three types of fertilizer were applied to Brassica campestris L.The results demonstrate that compared to control,no fertilizer at all,the yield of Brassica campestris L.was greatly increased by 188% by the application of combination of organic and inorganic fertilizer.Detection of N,P2O5,K2O content in the plants displayed that vegetable-specialized fertilizer significantly facilitated samples＇ nutrients absorption ability,which was much more obvious than other treatments,the absorption of N,P2O5,K2O per 667 m2 was 4.05kg,1.85 kg and 8.55 kg respectively.The analyzes of soil nutrients content under three treatments after harvest found that the organic-only fertilizer dramatically increased all kinds of nutrient in soils and pH value.
