| 摘 要： | 通过盆栽试验和土壤培养试验,研究了施用生物有机肥对芥蓝生长及土壤速效氮、磷、钾含量的影响.结果表明:施用生物有机肥能使芥蓝的产量显著提高,在肥力偏低的土壤上施用效果更好,每500 g土施用生物有机肥3 g,即达到施用常规化肥的效果.施用生物有机肥有利于促进蔬菜体内氮、磷、钾养分的积累,显著提高土壤中速效氮、磷、钾含量,改善土壤的供肥能力,在肥力偏低的土壤上可得到更好的效果.

| Abstract: | The pot experiment and soil incubation experiment were conducted to study the effect of bio-organic fertilizer on Brassica alboglabra, Chinese kale, growth and soil N, P, K content. The results showed that bio-organic fertilizer could significantly increase yield of the Chinese kale particularly in low-fertility soil. Application of bio-organic fertilizer could improve the accumulation of N, P, K in Chinese kale. The nutrient accumulation was increased by the increase of fertilizer application. Bio-organic fertilizer remarkably improved the soil supplying fertilizer ability, and raised the soil N, P, K content. |
