| 摘 要： | 采用配方施肥方案进行磷、钾肥效试验(3次重复,9个处理),研究磷钾肥配施对紫云英种子产量的影响,并筛选出适宜的磷、钾用量。结果表明,所有施肥处理的种子产量都高于不施磷钾肥即P0K0与P0K0相比,各施肥处理P1K2,P2K1,P1K1,P2K3,P2K2,P3K2,P2K0和P0K2留种产量分别提高了35.91%,35.37%,21.21%,20.79%,10.82%,10.20%,1.81%和1.47%。P1K2和P2K1这2个处理都显著或极显著高于P1K1,P2K3,P2K2,P3K2,P2K0,P0K2,P0K0。在性状特征方面(株高、茎粗、每分枝结荚花序数及结荚数),P2K3和P3K2相对优于其它施肥处理。可见,合理配施磷钾肥对提高紫云英种子产量有重要影响。

| Abstract: | The test adopted fertilization program （three replicates, nine treatments） to study the P and K fertilizer on the seed yield of Chinese milk vetch, and selected the appropriate phosphorus, potassium consumption. The results showed that the seed yield of all fertilization treatments were higher than not applied P and K （P0K0）. Compared with the PoKo, the seed yields of fertilization treatments P, K2, P2K1, P1K1, P2K3, P2K2, P3K2, P2K0 and P0K2 were increased by 35.91%, 35. 37%, 21.21%, 20. 79%, 10. 82%, 10. 20%, 1.81% and 1.47% ,respectively. Both treatments of PIK2 and P2KI were significantly or extremely significantly higher than the P1K1, P2K3, P2K2, P3K2, P2Ko, PoK2 and PoKo. In terms of characteristics of the traits （plant height, stem diameter, inflorescence number per pod and pod branch number）, both P2 K3 and P3 K2 were relatively better than other fertilizer treatments. Thus, applied reasonably P and K fertilizer had a major impact on improving seed yield. |
