苜蓿的矿质营养是苜蓿合理施肥的理论基础和优质高产的重要物质保障,它不仅与人、畜的营养和健康状况密切相联,而且对有机农业或生态农业的研究、土壤肥力的提高、环境污染的减少以及能源的节约有重大影响。因此,关于苜蓿的矿质营养受到国内外的高度重视和广泛研究。这里谈谈苜蓿的氮、磷、钾、镁、硫和钙等大量元素营养的某些问题(大量营养元素中的碳、氢、氧从略)。
The mineral nutrition of alfalfa is the theoretical basis of rational fertilization of alfalfa and the important material guarantee of high quality and high yield. It is not only closely linked with the nutrition and health of human and livestock, but also the research of organic agriculture or ecological agriculture, the improvement of soil fertility, The reduction of pollution and energy conservation have a significant impact. Therefore, the mineral nutrition of alfalfa is highly valued and extensively studied both at home and abroad. Here to talk about alfalfa nitrogen, phosphorus, potassium, magnesium, sulfur and calcium and other nutrients of some of the large number of nutrients (a large number of nutrients in the carbon, hydrogen, oxygen slightly omitted).
