摘　　要：为明确黑土心土培肥不同磷物料效果,通过小区比对试验方法,采用自主研发的土壤深耕犁和心土培肥犁分别对嫩江薄层黑土进行心土培肥试验,比较5种不同磷肥(P_2O_5含量22.5%的磷矿粉、44%的磷酸一铵、28%的磷矿粉、46%的重过磷酸钙、12%的过磷酸钙)心土培肥效果,明确了不同磷物料心土培肥对大豆生育性状、产量及品质的影响。结果表明:不同磷物料对大豆生育及产量影响差异显著,盛花期和结荚期叶绿素含量也有显著差异,综合比较P_2O_5含量44%的磷酸一铵处理增产效果最显著,比对照组增产32.79%,且大豆叶绿素含量、干物质重量比对照提高9.7%和35.5%,蛋白质含量提高3.45%,同时高于其它磷物料培肥处理,因此心土培肥应根据生产实际条件选择相应的培肥物料,更加利于大豆产量的提高。In order to clarify the effects of different phosphorus materials in subsoil fertilizing on soybean growth, we compared five different phosphate fertilizers treatments（22. 5% of P2O5 content ground phosphate rock, 44% of P2O5 content monoammonium phosphate, 28% of P2O5 content ground phosphate rock, 46% of P2O5 content triple superphosphate, 12% of P2O5 content superphosphate） in subsoil-fertilizing, by using the subsoil plough and subsoil fertilizer plough in Nenjiang. The results showed that different phosphorus materials had significant difference in soybean fertility and yield. There were significant difference in chlorophyll content at full-blossom period and fruiting period. The soybean chlorophyll content and dry matter weight of 44% P20s content monoammonium phosphate treatment was maximum, which increased 9.7% and 35.5% than the control group （CK）, also higher than other different phosphorus fertilizer treatments, the yield increased significantly by 32. 79% than the CK, and protein content was as high as 42. 2%. The subsoil fertilizer should choose the suitable fertilizer materials according to the actual production conditions.
