| 摘 要： | 采用部分"3414"肥料效应试验设计方案进行田间试验,研究了氮、磷、钾配施对紫云英性状指标、鲜草产量及植株养分含量的影响,并筛选出适宜的氮、磷、钾肥用量。结果表明,施肥处理比不施肥处理,株高、茎粗、分枝、根瘤数、单株重和鲜草产量最大增幅分别为13.50%、42.34%、18.75%、18.18%、87.07%和33.22%。与不施肥处理相比,9个施肥处理紫云英鲜草产量平均增产9 591.9 kg/hm2,提高了13.50%。处理7(N0P3K2)即高量磷和中量钾配施的鲜草产量最高,达到94 641.6 kg/hm2,与不施肥处理相比,增产了33.22%。处理7对紫云英植株养分含量(N、P、K)的累积最大,与不施肥处理相比,N、P、K养分含量分别提高了16.53%、34.40%、24.47%。可见,增施磷钾肥是提高当前肥力水平下紫云英产量与植株养分累积的有效途径。合理施用N、P、K肥能明显促进紫云英的生长,提高产量和养分积累量,对翻压紫云英作绿肥,减少化肥施用量,有重要的生态环境效益。 |

| Abstract: | Suitable nitrogen,phosphorus,potassium fertilizer consumption was screened out,using some of the "3414"fertilizer effect of trial design for field trials to study the nitrogen,phosphorus and potassium fertilizer on Chinese milk vetch character,yield of fresh grass and nutrient content.The results indicated that plant height,stem diameter,branch,root nodule,plant weight and yield of fresh grass showed the largest increase at 13.50%,42.34%,18.75%,18.18%,87.07% and 33.22% comparing to non-fertilization.The average yield of fresh grass with nine fertilization treatment increased by 13.50%(9 591.9 kg/hm2)comparing to no fertilizer treatment(N0P0K0).The highest yield of fresh grass for treatment 7(N0P3K2)reached to 94 641.6 kg/hm2,increased by 33.22%,compared with no fertilization.Treatment 7(N0P3K2)that combined high levels of phosphorus and mid-levels potassium had more plant nutrient content than no fertilizer.Compared to treatment 1,N,P and K nutrients content were increased by 16.53%,34.40% and 24.47%,respectively.It was an effective way to improve the current level of fertility and plant nutrient accumulation of Chinese milk vetch yield through increased P,K fertilizer.Thus,reasonable application of N,P,K fertilizers could significantly promote the growth of Chinese milk vetch,improve yield and nutrient accumulation,and also reduce the amount of chemical fertilizer when Chinese milk vetch was turned pressure as green manure,which have important eco-environmental benefits. |
| Keywords: | Chinese milk vetch fertilization yield of fresh grass nutrient content |
