Abstract:

To study the effects of different foliar fertilizers on the production performance of regrowing alfalfa, the general nutritional contents of the second crop of regrowing alfalfa sprayed the (NH4)6Mo7O24, FeSO4 and CH4N2O of different rates were analyzed by Grey correlative analysis using alfalfa ‘Longmu 801’ as the test material. Results indicated that the correlation degrees of combining 0.1% FeSO4 with 0.05% (NH4)6Mo7O24 ranked the first, and alfalfa had the best productive performance. As the rate of CH4N2O was 0.3%, the correlation degrees of spraying only CH4N2O ranked the top of all the treatments. It indicated that the effects of spraying FeSO4 and (NH4)6Mo7O24 on alfalfa productive performance were influenced by CH4N2O.

摘要:

为研究不同叶面肥对苜蓿(Medicago)再生草生产性能的影响,以苜蓿‘龙牧801’(Longmu 801)为研究材料,对其第2茬再生草喷施不同浓度配比的钼酸铵、硫酸亚铁和尿素,并进行常规营养含量的灰色关联度分析。结果表明:在0.1%的硫酸亚铁与0.05%的钼酸铵配合施用时,关联度综合排名最高,在此浓度组合下苜蓿具有最佳生产性能;在尿素为0.3%的水平下,所有处理中只喷施尿素组关联度排名最高,表明硫酸亚铁和钼酸铵对苜蓿营养产量的作用受到了尿素的影响。
