| 摘 要： | 采用叶面喷施的方法,研究了喷施不同浓度锰对紫花苜蓿草产量和营养品质的影响。结果表明,喷施硫酸锰可显著(P<0.05)提高苜蓿草产量,以喷施锰浓度为100 mg/kg效果最好,年总产量达14 268.88 kg/hm2,产量比对照提高24.0%。喷施硫酸锰可以显著提高苜蓿粗蛋白的含量,当喷施浓度为100 mg/kg时效果最显著;而喷施锰肥后苜蓿粗灰分有所降低;粗纤维含量有增加的趋势;不同茬次对粗脂肪含量影响效果有较大差异,以200 mg/kg(Mn2)处理更能提高粗脂肪含量;喷施锰肥对无氮浸出物含量影响不明显。营养物质的年积累量均以喷施浓度为100 mg/kg时最高。 |

| Abstract: | The effect of manganese sulfate application by leaf surface spurting at different levels on yield and quality of alfalfa was studied.The result indicated that spurting manganese sulfate could remarkably(P<0.05)increase the yield of alfalfa.Among the three spurting treatments the effect of 100 mg/kg level was the best,compared to CK,the grass yield increased by 24.0%.Different spurting manganese sulfate treatment could remarkably increase the crude protein content,and when manganese sulfate concentration was... |
