一、速测技术及其应用特点 1.速测的意义:土壤养分速测是一种相对于常规分析,速度更快捷,成本更低廉,测试设备更简便,而测试精度能满足测土施肥要求的土壤养分测试技术与装备。其核心是降低土壤测试的成本。由于常规分析成本较高(每个项目一般要30—50元),我国田块通常很小,田块肥力不均,测土代表的面积常常只有几亩,测土投入往往大大超过测土的产出,这已经成为我国推广测土施肥的制约因素。也正因如此,肥料厂家进行农化服务对测土投入往往超过售肥收益。根据我国土 First, the rapid measurement technology and its application characteristics 1. Speed ​​measurement significance: soil nutrient rapid measurement is a relative to conventional analysis, faster, cheaper, more convenient test equipment, and test accuracy can meet the soil fertilization requirements Soil nutrient testing technology and equipment. The core is to reduce the cost of soil testing. Due to the high cost of conventional analysis (each project generally 30-50 yuan), plots in China are usually small, uneven fertility plots, soil surface area is often represented only a few acres, soil testing is often much more than soil testing Output, which has become China’s promotion of fertilization soil testing constraints. Precisely because of this, fertilizer manufacturers for agricultural services on soil testing often exceed sales revenue. According to my soil
