采用田间试验,研究不同有机肥水平及配施化肥对低产田苜蓿的产量、营养品质及经济效益的影响。结果表明,施肥对低产田苜蓿草产量具有显著影响(P <0.05),不论单施有机肥还是配施磷钾肥,苜蓿产量均得到提高,有机肥配施磷钾肥的3个处理显著提高苜蓿产量,第1、2茬苜蓿产量均以处理 OF3 PK 增产最高,与对照相比分别增加了278.16%、276.54%,与其余各处理间差异显著(P <0.05)。有机肥与磷钾肥配施能明显改善苜蓿营养品质,其中,粗蛋白含量得到显著提高,中性洗涤纤维和酸性洗涤纤维含量显著降低,综合分析,处理 OF3 PK 苜蓿营养品质最佳。产投比以处理 OF2 PK 最高,OF3 PK 次之,均有较好的经济效益。通过对苜蓿产量、营养品质及经济效益的综合全面的分析,处理 OF3 PK 在实际大田生产中更适合进行推广。
採用田間試驗,研究不同有機肥水平及配施化肥對低產田苜蓿的產量、營養品質及經濟效益的影響。結果錶明,施肥對低產田苜蓿草產量具有顯著影響(P <0.05),不論單施有機肥還是配施燐鉀肥,苜蓿產量均得到提高,有機肥配施燐鉀肥的3箇處理顯著提高苜蓿產量,第1、2茬苜蓿產量均以處理 OF3 PK 增產最高,與對照相比分彆增加瞭278.16%、276.54%,與其餘各處理間差異顯著(P <0.05)。有機肥與燐鉀肥配施能明顯改善苜蓿營養品質,其中,粗蛋白含量得到顯著提高,中性洗滌纖維和痠性洗滌纖維含量顯著降低,綜閤分析,處理 OF3 PK 苜蓿營養品質最佳。產投比以處理 OF2 PK 最高,OF3 PK 次之,均有較好的經濟效益。通過對苜蓿產量、營養品質及經濟效益的綜閤全麵的分析,處理 OF3 PK 在實際大田生產中更適閤進行推廣。

The effect of combined application of organic fertilizer with different application levels and P,K fertilizers on the yield,nutrient quality and economic efficiency of lower yield alfalfa (Medicago sativa L.)was studied in field.The result indicated that the fertilization showed a significant impact on the low-yielding fields of alfalfa (P <0.05),both single application of organic fertilizer and mixed with P and K fertilizers increased al-falfa yields to varying degrees.3 treatments of organic fertilizer combined with P,K fertilizers significantly in-creased the yield of alfalfa,the hay production of OF3 PK treatment was the highest,which was increased by 278.1 6% and 276.54% compared to CK,it was also significantly higher than the rest treatments(P <0.05 ). The application of organic fertilizer combined with P,K fertilizers could significantly improve alfalfa quality as well,and it could significantly increase the crude protein content and decrease the neutral detergent fiber and acid detergent fiber contents.The output ratio of OF2 PK treatment was the best,and followed by OF3 PK.Both OF2 PK and OF3 PK treatments showed a better economic efficiency.
