为了平衡及优化营养与提高单位面积产量,特别是在灌溉地上施用肥料和微量元素对玉米茎叶和籽粒化学成分变化的研究具有很大意义。因此,研究了施用微肥的各种方法。研究是在第聂伯罗彼得罗夫斯克地区玉米科学生产联合公司《第聂伯》试验农场进行的。土壤为少腐殖质中度淋溶的中壤质普通黑钙土。腐殖质含量为3.1～3.8%,易水解氮为50～55毫
In order to balance and optimize the nutrition and improve the yield per unit area, especially the application of fertilizers and trace elements in the irrigation field on the chemical composition changes of stems and leaves of corn and the study of great significance. Therefore, various methods of applying micronutrients have been studied. The study was conducted at the “Dnepr” pilot farm of Corn Scientific Production Union in Dnipropetrovsk. Soil is less humus moderate leaching of loam in the ordinary chernozem. Humic content of 3.1 to 3.8%, easily hydrolyzed nitrogen 50 ~ 55 milliliters
