| 中文摘要: |
| 采用盆栽试验,设置不施磷(P0)和施0.15 mg P2O5/kg土(P1)两个处理,研究了33个河南省地方性大豆品种磷素营养特性的差异,旨在为磷高效大豆种质资源的开发利用提供依据。结果表明:根据大豆品种不同磷营养性状进行聚类分析,可将磷胁迫条件下供试大豆品种分为3类,其中第一类品种(产量高、磷吸收量大、磷利用效率中等)综合磷营养性状值最优;磷充足条件下供试大豆品种可分为4类,其中第一类品种(籽粒产量高,磷吸收量大,磷利用效率较高)综合磷营养性状值最好。相关分析表明,大豆苗期与成熟期的磷吸收量之间的相关性达显著以上水平(P0,r=0.5096**;P1,r=0.3596*);大豆苗期,磷素吸收总量和植株生长量的相关性较高(P0,r=0.8124**;P1,r=0.8724**),对生长起决定作用;成熟期,磷素利用效率对籽粒产量的影响有所增加,但是磷素吸收总量对籽粒产量的影响仍大于磷素利用效率。 |

| The difference of phosphorus nutrition characteristics of 33 soybeans varieties were studied with pot experiment and with two phosphorus fertilizer(P2O5) rate treatments of P0(0 mg/kg) and P1(0.15 mg/kg) to provide evidence for exploration and utilization of soybeans phosphorus efficiency germplasm.The results showed that in P deficient condition,the tested soybean varieties were classified to three classes by dendrogram by those nutrition traits,among which class1(with highest seed yield and P accumulation quantity,and with medium P utilization efficiency) showed best complex phosphorus nutrient trait;in P abundant condition,the tested soybeans varieties were classified to four classes,among which class 1(with highest seed yield and P accumulation quantity,and with higher P utilization efficiency) showed best complex phosphorus nutrient trait.Statistical analysis showed that the correlation between the plant P accumulation in seedling and harvesting reached over significant level (P0,r=0.5096**;P1,r=0.3596*);in seedling,the plant P accumulation had significant correlation with plant dry weight(P0,r=0.8124**;P1,r=0.8724**) and dominated the plant growth;in harvesting,the effect of P utilization on seed soybean yield increased;but which still was less than that of P accumulation. |
