近年来,人们对分析植株组织以测定甘蔗营养需要的优点日益关注。在甘蔗生产中有16种元素被认为是必需的,其中要算氮素对甘蔗生长和蔗汁品质的影响最大。文献资料为氮素的施用部位和施用时间提供了充分的证明。但精确测定氮素的需要量是一个难题,这是因为不同的土壤类型有不同的矿化氮量,并且季节因素也影响矿化
In recent years, there has been growing concern with the advantages of analyzing plant tissue to determine the nutritional needs of sugarcane. Sixteen elements in sugarcane production are considered essential, with nitrogen being the most important contributor to sugarcane growth and sugarcane juice quality. The literature provides sufficient evidence for the site and time of application of nitrogen. However, accurate determination of the nitrogen requirement is a challenge because different types of mineralization have different levels of mineralized N and seasonality also affects mineralization
