摘要
采用正交设计对平欧杂种榛幼树进行施肥试验,探讨不同施肥处理条件对平欧杂种榛苗期生长状况的影响,通过测定苗高、地径、新梢生长量及叶面积等生长指标,并综合幼树生长指标比较以及生物量的结果可知:以施N肥(尿素)41g/株、P肥(过磷酸钙)79 g/株、K肥(硫酸钾)58 g/株,以及微量元素镁(硫酸镁)3 g/株为最佳施肥方案。
In this paper,the orthogonal design was used to carry out the fertilization experiment on the hybrid hazelnut young trees.The effects of different fertilization treatments on the growth of Hybrid Hazelnut seedlings were discussed.By measuring the growth indexes of seedling height,ground diameter,new shoot growth and leaf area,the best fertilization amount of Hybrid Hazelnut young trees was determined.According to the comparison of growth indexes and biomass of young trees,the best fertilization scheme is N fertilizer(urea)41 g/plant,P fertilizer(superphosphate)79 g/plant,K fertilizer(potassium sulfate)58 g/plant and trace element magnesium(magnesium sulfate)3 g/plant.
