炭基肥对土壤性质以及蔬菜生长的影响

Effects of Carbon-based Fertilizer on Soil Properties and Vegetable Growth

[目的]促进炭基肥的研究和农用。[方法]采用盆栽试验,研究炭基肥和复合肥不同施用对土壤部分化学性质、养分状况及3种不同品种蔬菜(奶油小白菜、四季小白菜、小青菜)植株养分、SPAD值及产量的影响。[结果]与普通复合肥相比,炭基肥可显著提高土壤有机质含量和阳离子交换量,蔬菜叶片SPAD值、产量、植株全磷和全钾含量。[结论]生物炭基肥可部分替代传统化肥,降低化学肥料的施用量,但不会影响产量;还能促进蔬菜对全磷、全钾养分的吸收利用并保持生物炭改良土壤的功能。

[Objective]To facilitate the research and application of carbon-based fertilizer in agriculture.[Method]The pot experiment was conducted to study the effects of carbon-based fertilizer and compound fertilizer on soil chemical properties,soil nutrients,and the nutrients,SPAD value and yield of three different vegetables(cream cabbage,four seasons cabbage,green stuff).[Result]Compound with compound fertilizer,carbon-based fertilizer could significantly increase soil organic matter,cation exchange capacity(CEC),SPAD value,yield,the total phosphorus and potassium contents in vegetables.[Conclusion]Carbon-based fertilizer can partially replace traditional chemical fertilizer and reduce the amount without affecting the yield of vegetables;it can also promote the absorption and utilization of total phosphorus and potassium nutrients in vegetables and maintain the biochar’s function in improving soil.
