喷施锌、硼、锰肥对兰州百合干物质积累分配、产量和氮磷吸收的影响

摘要

Combining field investigation and laboratory analysis,the effects of different concentration of boron,zinc,manganese fertilizer on accumulation and distribution of dry matter, yield and N P asorption of Lilium davidii var. unicolor was studied. The results showed that 200 mg/L zinc fertilizer, 100 mg/L boron fertilizer, 100 mg/L manganese fertilizer improved the asorption and transferring of N P and quality of bulb, increased the yield of bulb and fertilizer efficiency.%采用田间试验与室内分析相结合的方法,研究了不同浓度Zn、B、Mn肥喷施对兰州百合干物质积累分配、产量和氮磷吸收的影响.结果表明,在氮磷钾肥充足的土壤中,喷施浓度为200 mg/L Zn肥、100 mg/L B肥和100 mg/L Mn肥均能有效促进兰州百合对氮磷的吸收转运,增加兰州百合鳞茎产量,改善鳞茎品质,提高肥料的利用效率.
