不同土壤类型生长的甘蔗,需要不同比例的氮、磷、钾配合施用,才能获得高产、稳产、低成本的效果。目前确定推广氮、磷、钾的配比沙围田蔗区为4:1:1,岗地赤红壤蔗区为6:1:2。基水地蔗区的配比则有多种提法,如4:1:1,4:1:1.5,2:1:2等,效果不一。为了研究基水地区
Different types of soil to grow sugarcane need different proportions of nitrogen, phosphorus and potassium with the application, in order to obtain high yield, stable yield, low cost effect. At present, it is determined that nitrogen, phosphorus and potassium are distributed in a ratio of 4: 1: 1 in sugarcane field and 6: 1: 2 in sugarcane red field. Base water sugarcane area there are a variety of formulation, such as 4: 1: 1, 4: 1: 1.5, 2: 1: 2, with different results. In order to study the base water area
