摘要:
为提高土壤中潜在磷素的有效性,提高磷肥利用率,采用盆栽试验研究施用不同种类的溶磷混合菌肥后石灰性土壤磷素养分及解析特性的变化. 结果显示:与单施有机肥相比,施用溶磷混合菌肥,可以增加油菜土壤有效磷和磷酸酶活性及油菜品质,其中施用组合溶磷细菌肥效果最显著,较之单施有机肥,土壤有效磷含量、酸碱磷酸酶活性、油菜干重、鲜重、吸磷量显著增加,分别提高15.44%、10.49%、14.25%、34.45%、27.80%、67.18%;土壤pH值和油菜叶绿素含量变化不显著. 施肥可以改变土壤磷的吸附–解吸特性,与其它处理相比,施用溶磷混合菌肥,土壤最大吸磷量Xm和吸附系数k以及土壤最大缓冲容量MBC均降低,土壤磷解吸量及解析率增加,在不同种类的溶磷混合菌肥中,组合溶磷细菌处理对土壤磷的吸附–解吸影响最显著,该处理下土壤中磷的最大吸附量和土壤最大缓冲容量分别为370.88 mg/kg和502.45 mL/g,比组合溶磷真菌、组合溶磷细菌真菌复混处理分别降低了12.47%和16.19%、13.38%和14.37%. 本研究表明加入溶磷混合菌肥,特别是组合溶磷细菌肥可以促进土壤磷的活化,降低吸附,减少磷素化肥的施用,提高土壤中磷素的利用率,结果可为农业生产中石灰性土壤上磷肥的合理施用提供理论依据. 图3 表7 参25
Abstract:
To improve the availability of potential phosphorus in soil and the utilization rate of phosphate fertilizer, we set a pot experiment to study the change of different types of dissolved phosphorus microbial mixed fertilizer on phosphorus nutrient and phosphorus adsorption-desorption characteristics in calcareous soil. The result showed that application of dissolved phosphorus microbial mixed fertilizers could increase the rapidly available phosphorus content, soil phosphorus content and the quality of rapeseed, with combined dissolved phosphorus bacteria fertilizer the most effective among all types of dissolved phosphorus microbial mixed fertilizer. Soil rapidly available phosphorus content, acid and alkaline phosphatase activity, rapeseed dry weight, fresh weight and phosphorus uptake were all significantly higher than those with application of single organic fertilizer, by 15.44%, 10.49%, 14.25%, 34.45%, 27.80% and 67.18% respectively; while soil pH and chlorophyll content of rape did not show significant difference. Fertilization was found to change soil phosphorus adsorption-desorption properties. Compared with other processing, application of dissolved phosphorus microbial mixed fertilizer decreased soil largest phosphorus uptake Xm, adsorption coefficient k and soil largest buffer capacity MBC, but increased soil phosphorus desorption quantity and resolution, with combined dissolved phosphorus bacteria fertilizer the most effective among different types of dissolved phosphorus microbial mixed fertilizer. With application of the combined dissolved phosphorus bacteria fertilizer, the soil largest phosphorus uptake was 370.88 mg/kg, 12.47% lower than that with application of combined dissolved phosphorus fungus, and 16.19% lower than that with application of combined dissolved phosphorus bacteria mixing fungi; the soil largest buffer capacity was 502.45 mL/g, 13.38% lower than that with application of combined dissolved phosphorus fungus, and 14.37% lower than that with application of combined dissolved phosphorus bacteria mixing fungi. The results indicated that phosphorus adsorption-desorption characteristics can provide theoretical basis for reasonable use of phosphate fertilizer in calcareous soil. Applying dissolved phosphorus microbial mixed fertilizer, especially combined dissolved phosphorus bacteria fertilizer, can promote activation of soil phosphorus, decrease adsorption, reduce phosphorus fertilizer application and enhance utilization rate of phosphorus in soil, therefore avoid waste of material and damage to the environment.
