马铃薯不同器官的养分含量动态变化研究

通过种植试验,研究分析了马铃薯各生育时期不同器官的氮,磷,钾、硫、钙、镁等养分的含量动态变化规律,结果表明,马铃薯植株各生育时期的6种养分含量大小均表现为:钾>氮>钙>磷>镁>硫,且随着生长时间的延长总体上均呈现下降的趋势,但各自峰值不同,该研究结果为马铃薯高产、优质种植施肥技术方案设置提供了依据.

Study on the dynamic change of nutrient content of potato

In this paper,field experiments were conducted to study the various growth stages of potato in different organs of the N,P,K,S,Ca,Mg and other nutrients in the dynamic changes of content,research results showed that whole-plant nutrient content of potatoes in various growth stages were expressed as K > N> Ca> P> Mg> S,and generally showed a downward trend,but each peak was different for high-yield,high-quality potato fertilization provides a theoretical and technical basis.
