| 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 treat-ments 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 sig-nificant , 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 super-phosphate 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 inor-ganic fertilizers can significantly promote YNCP growth , and 14 kg pig manure +1.5 kg calcium super-phosphate per tree have the best promoting effect . |
