摘  要:
对国家缓控释肥工程技术研究中心分离保藏的一株溶磷真菌PSFK的溶磷性能进行研究,并进行盆栽试验,研究其对鸡毛菜的促生作用。结果表明,PSFK菌株具有很强的降解无机磷能力,在以Ca3(PO4)2为唯一磷源的无机磷液体培养基中培养6 d水溶磷含量达到886.2 mg/L,为对照组的89.92倍。在土壤中培养50 d,有效磷含量升高27.19 mg/kg。PSFK菌剂对鸡毛菜的促生作用明显,以添加2%菌剂的处理增产效果最好,显著提高鸡毛菜的生物产量和叶片数。鲜质量与单施硝基肥处理相比差异极显著,增幅达到32.94%,干质量增幅达到29.37%,有明显的促生作用。

摘  要:
A dissolving phosphate fungi( PSFK) of this laboratory separation and preserved was studied by the research of phosphate-dissolving characteristics and rape potted planting experiment. The results show that PSFK has strong ability of degradation of inorganic phosphorus and obvious promoting effect. After 6 days fermentation in the medium with Ca 3( PO 4) 2 as the sole phosphorus source,soluble phosphorus content reached to 886. 2 mg / L,which is 89. 92 times higher than that of control group. What's more,available phosphorus content increased 27. 19 mg / kg after 50 days cultivation in soil. PSFK has obvious effect on promoting growth of Brassica chinensis,the adding of 2% PSFK has the best effect on increasing the biological yield and number of leaves significantly. Compared with the single application of nitro fertilizer,fresh weight and dry weight was increased by 32. 94% and 29. 37% respectively. PSFK shows evident promoting effect on plant.
