摘要
针对燕山板栗施肥不均衡、不合理现状,进行钙、镁、硼、锌营养元素施肥量试验。测定其产量及土壤与叶片养分含量,分析施肥量与上述指标的相关性。结果表明:在缺乏营养元素的板栗土壤上施用镁、硼、锌肥均有明显增产效果;各元素施肥经济合理推荐量为镁肥∶硼肥∶锌肥比例为1∶1∶1。
Considering at Yanshan Mountain chestnut soil fertilization imbalance,unreasonable status,and calcium,magnesium,boron,zinc nutrition elements fertilizer effect tests were finished,we determined the yield and nutrition element contents of soil and leaves,as well as analyzed the correlation between above indexes and fertilizer amounts.The results showed that the less nutrition chestnut soil which into application of magnesium,boron,zinc fertilizer were significantly effect on yield increase,and for economic reasonable,the application ratio of magnesium and boron and zinc fertilizer was recommended 1∶1∶1.
