中华红叶杨幼林施肥试验

Research on Fertilizer Application of Young Populus deltoids cv. Zhonghuahongye Growth

    摘要
  • 摘要: 在成都市新都区灰色潮土上采用完全设计和正交设计方法,进行中华红叶杨幼林施肥试验。结果表明:单一养分元素肥料施用效果K > N > P,肥料配合施用效果N+P+K > N+K > N+P、P+K,适宜的施肥配方为尿素150 g·株-1+过磷酸钙220 g·株-1+硫酸钾75 g·株-1。

     

    Abstract: The trials of fertilization using complete and orthogonal design for the young growth of Populus deltoids cv. Zhonghuahongye were conducted on the fluviogenic soil in Xindu District of Chengdu City. The results showed that the effects of single nutrient element fertilizer and mixed fertilizer were K > N > P and N + P + K > N + K > N + P and P + K,respectively,and it was obvious for the effect of fertilization formula of 150 g(NH2)2CO + 220 g Ca(H2PO4)2·H2O + 75 g K2SO4 for each tree.
