摘要
1980～1986年,在山西石灰性褐土上进行了玉米施锌的长期定位试验和磷锌配合的盆栽试验。结果表明。玉米施锌能促进营养器官生长、根系发育和体内物质转化、酶的活性及繁殖器官的发育,具有显著而稳定的增产效果,并能提高多种氨基酸的含量。锌磷配合施用明显增加玉米幼苗的干物质重,玉米幼苗生长对磷锌数量有一定要求,锌磷肥的均衡施用有助于提高肥效。
During the period of 1980 to 1986,a long-term experiment of application of zinc on maize and a pot experiment of application of zinc together with phosphorus were performed on a calcareous drab soil The result of the ex- periment shows that zinc applied to maize can promote the vegetative growth, development of root systems and reproductive organs,increase the enzyme activity and dry matter transformation,and it also shows the marked and stable efficiency increase in yield and amino acids content of many kinds. The zinc plus phosphorus on maize increases seedling dry matter,and a bal- anced proportion of Zn and P for maize seedlings are needed for improving the efficiency of Zn and P as fertilizers.Zine Einearel phosphorus,maize amino,aeid.
