为了研究磷锌配施对油菜养分吸收和土壤有效磷、锌的影响.采用盆栽试验,测定植株及土壤的养分浓度,根据测定结果进行分析.施用磷肥显著增加油菜的生物量,过量施用磷肥油菜生物量无显著影响;施锌对油菜的生物量无显著影响.增施磷肥显著增加油菜地上部和根中全磷;施用锌肥,油菜地上部和根中全磷无显著变化.增施磷肥显著降低了油菜地上部和根锌的浓度.施用锌肥,油菜地上部和根中锌浓度均显著上升.施磷对土壤有效锌无显著影响;施用锌肥显著增加了土壤有效锌,且随施锌量的增加而增加.施磷显著增加了土壤Olsen-P浓度;施锌不影响土壤Olsen-P浓度.随着施磷量的增加,土壤碱性磷酸酶、酸性磷酸酶及中性磷酸酶活性均逐渐下降.随着锌用量的增加,碱性磷酸酶和酸性磷酸酶活性呈先增加后降低的趋势;中性磷酸酶活性施锌后比不施锌处理显著增加,但随着锌用量的增加中性磷酸酶活性无显著变化.过量施用磷肥降低油菜体内锌浓度,施锌显著提高了土壤有效锌的浓度,改善了植株体内的锌营养状况.

The aim of this study was to determine the nutrient uptake of rape and the content of available phosphorus and zinc in soil under combined application phosphorus and zinc fertilizer.Based on the pot experiment,the nutrient concentration of plant and soil were measured.In addition,attributes of all results were recorded for dataset analyzing.The results showed that application of phosphate fertilizer significantly increased the biomass of rape,while there was no yield response when excessive phosphate fertilizer and zinc fertilizer were applied.The total P in rape shoot and root were increased gradually with the increase of phosphate fertilizer rate,while the total P both in shoot and root were not changed with the application of zinc.The zinc concentrations in rape shoot and root were deceased with the increasing application rate of phosphate fertilizer,while they were increased with the application of zinc.The soil available zinc concentration was gradually increased with the application of zinc,while it had no significant effect with the application of phosphate fertilizer.The soil Olsen-P concentration was gradually increased with the application of phosphate fertilizer,while it had no significant effect with the application of zinc.The alkaline,acid,neuter phosphatase activities in the soil were all deceased with the increasing application rate of phosphate fertilizer.The alkaline,acid phosphatase activities in the soil were increased first and then decreased with the increasing application of zinc.The neuter phosphatase activities in the soil was increased with the application of zinc comparing with the no zinc treatment,and it had no significant effect with the increasing application of zinc.Excessive application of phosphate fertilizer could reduce the zinc concentration.With the application of zinc,the soil available zinc concentration was increased.Therefore,the zinc nutritional condition of the plant was improved.
