    有机、无机肥配施对黄梁木幼林生长的影响

    Effects of combined application of organic and chemical fertilizers on growth of young Neolamarckia cadamba plantation

      摘要
    • 摘要:
      目的 探究有机、无机肥配施对黄梁木Neolamarckia cadamba幼林生长的影响。
      方法 采用林地现场小区试验法，对黄梁木幼林进行猪粪、鸡粪、过磷酸钙和氯化钾配施正交试验。
      结果 有机、无机肥配施能显著促进黄梁木幼林树高和地径生长，造林半年后，与未施肥相比，施肥处理树高和地径分别增加23.53%~109.41%和37.99%~149.06%；多因素方差分析显示，猪粪和过磷酸钙对黄梁木树高和地径生长有显著影响，其不同水平间差异显著，而鸡粪和氯化钾主效应不显著；综合考虑黄梁木生长状况和肥料成本，选择猪粪14 kg·株-1+过磷酸钙1.5 kg·株-1作为黄梁木幼林施肥方案；回归分析得出，猪粪(x1)和过磷酸钙(x2)施用量与黄梁木树高(yH)和地径(yD)之间的回归方程分别为：yH=1.016+0.031x1+0.221x2(R2=0.835, P=0.000)，yD=26.193+0.991x1+6.052x2(R2=0.83, P=0.000)。
      结论 有机、无机肥配施能显著促进黄梁木幼林树高和地径生长，当黄梁木施用猪粪14 kg·株-1+过磷酸钙1.5 kg·株-1时，促进作用最为明显。

       

      Abstract:
      Objective To explore effects of combined application of organic and chemical fertilizers on growth of young Neolamarckia cadamba plantation(YNCP).
      Method Impacts of combined application of pig manure, chicken manure, calcium superphosphate and potassium chloride on YNCP growth were studied by using orthogonal test.
      Result Combined application of organic and inorganic fertilizers had significant promoting effects on YNCP growth, with height and ground diameter growth of fertilized treatments being 23.53% -109.41% and 37.99%-149.06% greater than those of control treatment, respectively. Multivariate analysis indicated that pig manure and calcium superphosphate had significant effects on height and ground diameter growth, and differences among different fertilization levels were significant, but chicken manure and potassium chloride exhibited no significant effect. According to YNCP growth and fertilizer cost, the best fertilization solution was 14 kg pig manure+1.5 kg calcium superphosphate per tree. The regression equation between pig manure (x1), calcium superphosphate(x2) and tree height (yH) was yH=1.016+0.031x1+0.221x2 (R2=0.835, P=0.000), and the regression equation between pig manure, calcium superphosphate and ground diameter (yD) was yD=26.193+0.991x1+6.052x2 (R2=0.832, P=0.000).
      Conclusion Combined application of organic and inorganic fertilizers can significantly promote YNCP growth, and 14 kg pig manure + 1.5 kg calcium superphosphate per tree have the best promoting effect.
