为了促进南酸枣幼林的生长,采用配方施肥试验方法研究了不同施肥处理对南酸枣幼树生长的影响。结果表明:每株施放2.0kg有机肥,1年生南酸枣幼树胸径生长量提高了28.06%,树高生长量提高了22.32%;不同施肥配方中叶片的氮、磷、钾元素含量有显著性差异,但不同配方叶片氮、钾、磷元素含量均呈递减趋势:树高、胸径生长量最佳的处理12叶片中的氮、磷、钾含量也最高,与对照相比提高了35.03%、100.02%、52.87%;氮元素对幼年期南酸枣胸径、树高生长发育有极显著作用,磷、钾元素对南酸枣胸径生长发育有显著作用,这为南酸枣幼树平衡施肥提供了理论依据。

In order to promote the growth for young stand of Choerospondias axillaris as study the effects of different fertilization treatments on the growth of young stand. Results showed the diameter growth increase 28.06% and height growth increase 22.32% of annual Choerospondias axillaris with 2.0 kg organic fertilizer of per plant. The content of nitrogen, phosphorous, potassium contents in leaves exists significant differences on different formula fertilization, but the contents declined obviously along with the growth. The diameter and height growth and content of nitrogen, phosphorous, potassium...
