铁、锰、铜、锌、硼是作物生长所必需的微量营养元素,通称微肥。根据我省施用微肥的初步统计,铁、锰、铜、锌、硼对小麦、水稻、油菜、大豆、花生以及绿肥等作物均有不同程度的增产效果。微肥的应用日益广泛。我省江淮丘陵地区土壤的成土母质虽同属下蜀系黄土,但由于地形的差别,耕作利用方式的不同,因而形成了各种类型的土壤。如丘陵上部为黄泥土,多经营旱作;中部为白土,属于水旱两
Iron, manganese, copper, zinc and boron are essential micronutrients for crop growth, commonly known as micronutrients. According to the preliminary statistics of the application of trace fertilizers in our province, the output of iron, manganese, copper, zinc and boron to wheat, rice, rape, soybean, peanut and green manure all increased in different degrees. The application of micronutrient fertilizer is more and more widely. Although the soil parent materials of the soil in the Jianghuai hilly area belong to the loess loess area, the soil of different types is formed due to the difference in the topography and the different ways of tillage and utilization. Such as the upper part of the hills for the yellow soil, multi-operation dry farming; the middle of white soil, belonging to floods and droughts
