| 摘 要： | 在青海省循化县通过对大果沙棘实生苗进行二因素四水平的氮、磷肥配合施用试验，结果表明：大果沙棘向阳品种的株高、根径和根长随着过磷酸钙、尿素的施用量的增加而增加，在过磷酸钙400kg·hm^-2，尿素150kg·hm^-2以时，株高、根茎和根长均达到最大值，之后随着过磷酸钙、尿素的施用量的增加，株高、根茎和根长增加缓慢或下降。过磷酸钙400kg·hm^-2，尿素150kg·hm^-2是向阳大果沙棘最佳基肥配比施用量。

| Abstract: | Experiments of 2-factors-4-levels combined application of nitrogen and phosphorus of seedling of big fruit seabuckthorn in Xunhua county of Qinghai province were conducted.Result shows that:sunny plant height,root diameter & root length of big fruit seabuckthorn increase with the increment of application rate of calcium superphosphate & urea;plant height,root diameter & root length all reach the maximum while calcium superphosphate & urea is 400,150 kg·hm-2,respectively;then,plant height,root diameter & root length increase slowly or decrease with the increment of application rate calcium superphosphate & urea;400 kg·hm-2 calcium superphosphate and 150 kg·hm-2 urea is the optimum increment of application rate for base fertilizer for sunny big fruit seabuckthorn. |
