摘要:
为进一步减少化学肥料的使用、改善土壤状况,开展了以不同功能性微生物组合形成的菌肥(提升固氮能力的1号菌肥,促进钾吸收的2号、3号和4号菌肥,助益磷代谢的5号菌肥,及促进氮、磷、钾吸收的6号菌肥)对油茶叶内源激素及氮、磷、钾含量和林下土壤理化性质等影响的试验,施用6个月后,测定结果表明:施用4号菌肥的土壤含水率最高,且与施用1号、3号、5号、6号菌肥的土壤含水率差异显著;施用5号菌肥的土壤电导率显著高于施用1号、2号、3号、4号、6号菌肥及对照的土壤电导率;施用5号菌肥的土壤pH值最高,且与施用1号、2号、3号、6号菌肥及对照的土壤pH值差异显著; 6个菌肥施用区,油茶叶内的GA,IAA,ABA含量平均值显著高于对照区油茶叶内的含量,而叶内BR的含量平均值与对照区之间,均无显著差异;2号、3号、4号菌肥施用区,叶内氮相对含量与对照之间,具显著差异;6号菌肥施用区,叶内磷、钾相对含量最高;5号、6号菌肥施用区,叶内磷相对含量与2号菌肥施用区、对照组相比,具有显著性差异。该研究表明,施加微生物菌肥可对油茶叶内源激素含量及氮、磷、钾元素含量和林下土壤理化性质产生影响,尤以施用5号菌肥的效果最好。
Abstract:
In order to further reduce the use of chemical fertilizer and improve soil condition, trials were carried out to learn the effects of bacterial fertilizers formed by different functional microorganism combination (bacterial fertilizer:No 1 for improving nitrogen fixation ability;No 2,No 3 and No 4 for promoting potassium absorption;No 5 beneficial to phosphorus metabolism;and No 6 for promoting the absorption of nitrogen,phosphorus and potassium) on the soil physico-chemical properties, endogenous hormones and N, P and K content in Camellia oleifera Abel. leaves. It was found that six months after fertilization, the highest moisture occurred in the soil into which fertilizing No 4,significantly different from those soils relative to No 1,No 3,No 5 and No 6. The electrical conductivity of the soil relative to No 5 was significantly higher than those soils relative to No 1,No 2,No 3,No 4,No 6 and CK. The highest pH value occurred in the soil relative to No 5,significantly different from those in soils relative to No1, No 2, No 3, No 6 and CK. Average contents of GA, IAA and ABA in C. oleifera leaves in 6 bacterial fertilizers applying areas were significantly higher than those in CK while the average content of BR had no significant difference. Compared with CK, the relative contents of N in the leaves in the treatments of No 2,No 3 and No 4 were significantly different,the relative contents of P and K in the treatment of No 6 were the highest,and the relative contents of P in the treatments of No 5 and No 6 were significantly different from those in No 2 and CK. This study showed that applying different functionally-combined microorganism fertilizer could improve soil physico-chemical properties, endogenous hormone content and nitrogen, phosphorus and potassium in C. oleifera leaves. Among these bacterial fertilizers, No 5 performed the best effect.
