作者们进行了三年的田间试验以研究并比较各种微量元素播种前施于土壤及抽穗时施于地上部的效果以及这些元素对小麦(NP710)产量和品质的影响Cu,Mn,Zn 及 Mg 都用它们的硫酸盐,施于土中的每英亩用量各为5,10,5及10磅,喷施地上部的每英亩各为1磅。在施于土壤的情况下,所有处理都显著地增加了子粒产量,而以 Mn 的作用最大(NPK,NPKMn:1428,1861磅子粒/英亩)。所有各种微量元素除
The authors conducted a three-year field experiment to study and compare the effects of various trace elements applied to soil and heading to the shoot before sowing and the effects of these elements on the yield and quality of wheat (NP710) Cu, Mn, Zn and Mg uses their sulphate and is applied to the soil at 5, 10, 5, and 10 pounds each for acres and 1 lb. Per acre on the ground. When applied to soil, all treatments significantly increased grain yield while maximizing the effect of Mn (NPK, NPKMn: 1428, 1861 pounds of grain per acre). All kinds of trace elements except
