高陡岩壁木质藤蔓植物复绿栽培技术研究

Research on the Re-greening Cultivation Techniques for Woody Vine Plants in the High and Steep Rock Walls

为探究石灰岩矿山高陡岩壁环境下不同木质藤蔓植物复绿效果,采用L_(9)(3^(4))正交试验,测定不同处理条件下木质藤蔓植物覆盖高度、景观持续时长、景观衰败时长3个指标,并对各指标进行极差和方差分析,最终通过综合平衡分析找出最优组合。结果表明:植物种类、土层厚度、浇水间隔、氮肥用量对植物生长的影响各不相同,葛藤的覆盖高度最大;最佳的复绿栽培技术组合为葛藤+土层厚75 cm+浇水间隔10 d+氮肥用量30 g·m^(-2)。

In order to investigate the re-greening effect of different woody vine plants in the high and steep rock walls environment of limestone mines.The L_(9)(3^(4))orthogonal experiment was used to determine three indicators of cover height,landscape duration and landscape decay duration of woody vine plants under different treatment conditions,and the extreme difference and ANOVA were performed on each indicator to find the optimal combination by comprehensive balance analysis.The results showed that plant species,soil thickness,watering interval and nitrogen fertilizer dosage had different effects on plant growth,and Kudzu vine had the greatest cover height;the best combination of re-greening cultivation techniques was Kudzu vine+soil thickness of 75 cm+watering interval of 10 days+nitrogen fertilizer dosage of 30 g·Fm^(-2).
