氮素施用量对文冠果幼苗养分含量分布及转运效率影响的研究

Effects of Nitrogen Application Amount on Nutrient Content Distribution and Transport Efficiency of Xanthoceras sorbifolia Seedlings

通过设置不同的氮肥施用量处理,对文冠果幼苗内养分含量以及转运效率的变化进行研究,结果表明:氮肥施用量以250 mg株-1的处理对文冠果树幼苗养分含量的分布更加有利,且各种养分运转效率以氮素为最高,磷素水平最低。磷素可能是影响文冠果产量的一个重要因素,在生产中应注重磷元素的合理使用。

In order to explore the changes in nutrient content and translocation efficiency of the seedlings of different types of nitrogen fertilizers,eight different nitrogen fertilizer application rates were set up.The distribution of nutrient content of fruit seedlings is more favorable,and the operating efficiency of various nutrients is nitrogen is the highest,phosphorus is the lowest,so phosphorus may be an important factor affecting the yield of Xanthoceras sorbifolia.It is recommended to pay attention to the reasonable mix of phosphorus in production.
