一、绪言钾元索在合成植物有机物过程中,有特殊的作用,近几年来通过在不同植物上试验证明它是合成有机物的物质因素,与氮有密切的联系,因为植物合成有机物,钾和氮同时被植物根系吸收,在营养成分中它担任着重要任务,是农作物必须的营养 I. INTRODUCTION Potassium diethanolamine has a special function in the process of synthesizing organic compounds. In recent years, it has been proved by experiment on different plants that it is a material factor for the synthesis of organic compounds and is closely related to nitrogen because organic compounds, potassium and Nitrogen is absorbed by plant roots at the same time, which plays an important role in nutrients and is a necessary nutrient for crops
