采用快速的植株组织分析法,可以知道高产植株需要养分的关键时期以及植株在不同生育时期所需要养分的数量,是一种旱地作物营养条件诊断的好方法。这样,对生长着的植株,及时采取经济而有效的措施(如施肥等),以控制土壤养分的供应,使植株尽可能达到或接近需要的营养水平,从而取得高产。 在旱地作物氮素营养组织速测方面,通常都以 Using rapid plant tissue analysis, it is possible to know the critical period for high-yielding plant nutrients and the amount of nutrients needed by plants at different growth stages. This is a good way to diagnose the nutritional conditions of dryland crops. In this way, for the growing plants, timely and economical and effective measures (such as fertilization, etc.) to control the supply of soil nutrients, plants as close as possible or close to the desired level of nutrition to achieve high yield. Nitrogen nutrition in dryland crop tissue testing, usually to
