随着科学技术的发展,植物快速叶片全量分析已成为作物营养诊断的有效方法。近年来由于新的测试仪器的应用,给诊断分析带来很大方便,但也常因试样的预处理费时费工,而不能适应仪器分析速度快的要求。因此,改进分析技术,提高工作效率,是当前分析工作中急需解决的问题。关于植物叶分析,曾有人建议采用盐酸浸提的办法,因方法简便快速,颇为大家注意和重视。近几年我们用湿消化法与盐酸浸提的方法进行了一些试验比较,大多数元素测定值与湿消化法比较一致,一般能够反映植物中养分含量状况,但目前在运用中主要存在着铁的浸提量太低的问题,这样在分析包括铁在内的多元素含量时就有困
With the development of science and technology, full leaf rapid analysis of plants has become an effective method of crop nutrition diagnosis. In recent years, due to the application of new test equipment, it is very convenient for diagnosis and analysis, but it is often time-consuming and labor-intensive because of the pretreatment of the sample, which can not meet the requirement of high speed of instrument analysis. Therefore, improving analytical techniques and improving work efficiency are urgent problems to be solved in the current analytical work. About plant leaf analysis, it has been suggested that the use of hydrochloric acid leaching approach, because the method is simple and quick, quite everyone attention and attention. In recent years, we used wet digestion and hydrochloric acid leaching method to conduct a number of experiments, most of the elements measured values and wet digestion method is relatively consistent, can generally reflect the status of plant nutrient content, but the use of the main iron The problem of too low extractability, so there is difficulty in the analysis of multi-elemental content including iron
