施肥对祁连山沼泽湿地主要植物生长的影响

Effect of Fertilization on Growth of Main Plants in Marsh Wetland in Qilian Mountains

为了解不同施肥措施对祁连山沼泽湿地植物生长的影响,进行了区组试验研究。结果表明:高剂量的混合肥对地上部分生长效果最好,地上生物量达到了377.1g·m^(-2),比对照高41.5%;其次为中剂量混合肥,地上生物量为371.2g·m^(-2),比对照高39.0%。高剂量混合施肥区和中剂量混合施肥区差异不显著。从环保和节约资源的角度讲,建议采用中剂量混合施肥。

In order to understand the influence of different fertilization measures on the growth of marsh wetland plants in Qilian mountain,block test was conducted.Result shows that adopting high-dosed mixed fertilizer can obtain the optimal effect for the growth of plants above the ground,and the above-ground biomass are 377.1g·m-2,which are 41.5% higher than that of the control.Secondly,the medium dose of mixed fertilizer are optimal for the growth of above-ground part,and the above-ground biomass are 371.2g·m-2,which are 39.0% higher than that of the control.There is no significant difference between the treatment of high-dosed and medium-dosed mixed fertilizer application.However,from the perspective of environmental protection and resource conservation,the medium-dosed mixed fertilizer is recommended.
