摘要/Abstract

摘要：

在养分受限的农牧交错带盐渍化草地, 农业施肥诱导的氮输入增加和土地利用方式的改变通常会使土壤可利用养分发生变化, 进而影响植物净初级生产力。然而, 受年降水量的影响, 植物净初级生产力对氮添加与刈割的响应是否随降水量的改变而变化, 仍存在很大的不确定性。因此, 该研究以中国北方农牧交错带盐渍化草地为研究对象, 依托山西右玉黄土高原草地生态系统国家定位观测研究站的氮形态与刈割试验平台, 设置了包括对照和模拟氮沉降实验中常用的两种氮化合物(硝酸铵和尿素), 并与刈割和未刈割进行交叉处理, 共6个处理, 研究植物净初级生产力对氮添加与刈割的响应。研究结果表明: (1)无论在刈割还是非刈割处理下, 短期硝酸铵和尿素添加均显著提高土壤中无机氮含量, 进而提高植物地上(ANPP)、地下(BNPP)及总净初级生产力(NPP); (2) ANPP、BNPP、NPP、无机氮含量及土壤含水量表现出明显的年际差异, 具体表现为在湿润年(2018)显著高于干旱年(2017); (3)短期氮添加与年份的交互作用对NPP有显著影响。在湿润年, 氮添加对NPP的正效应显著高于干旱年, 这主要与土壤氮水的协同效应有关; (4)刈割降低了NPP, 且与年份的交互作用对BNPP:ANPP有显著影响; 在干旱年, 刈割整体降低了BNPP:ANPP, 然而, 在湿润年, 这种负效应逐渐减弱, 甚至转变为正效应。这些结果强调了自然降水量在调控农牧交错带盐渍化草地净初级生产力对人为干扰的响应中发挥着至关重要的作用, 也进一步说明农牧交错带盐渍化草地生态系统受氮和水的共同限制。

Abstract:

Aims In the salinized grassland of the agro-pastoral ecotone with limited nutrients, the increase of nitrogen input induced by agricultural fertilization and the change of land use patterns usually causes changes in soil available nutrients, which could further affect the net primary productivity of plants. However, due to the impact of annual precipitation, it is still uncertainty about whether the response of net primary productivity of plants to nitrogen addition and mowing varies with changes in rainfall.

Methods This study investigated plant net primary productivity under nitrogen addition and mowing at salinized grassland in the agro-pastoral ecotone of northern China, based on the experimental platform for nitrogen forms and mowing at the National Research Station of Grassland Ecosystems on the Loess Plateau in Youyu, Shanxi Province. There were six treatments including control and simulated nitrogen deposition experiments with two common nitrogen compounds (ammonium nitrate and urea), combined with and without mowing.

Important findings The results showed that: (1) Regardless of mowing or un-mowing treatments, short-term addition of ammonium nitrate and urea significantly increased the content of inorganic nitrogen in the soil, thereby increasing the aboveground (ANPP), belowground (BNPP), and total net primary productivity (NPP); (2) ANPP, BNPP, NPP, inorganic nitrogen content, and soil water content showed significant interannual differences, with higher values observed in the wet year (2018) than in the dry year (2017); (3) The interaction between short-term nitrogen addition and year had a significant impact on NPP. In the wet year, the positive effect of nitrogen addition on NPP was significantly higher than that in the dry year, which was mainly related to the synergistic effect of soil nitrogen and water; (4) Mowing decreased NPP and had a significant interactive effect with the year on the BNPP:ANPP. In the dry year, mowing generally decreased BNPP:ANPP. However, in the wet year, this negative effect gradually weakened and even turned into a positive effect. These results highlighted the crucial role of natural precipitation in regulating the response of net primary productivity of salinized grassland in the agro-pastoral ecotone to anthropogenic disturbances, and further indicated that the salinized grassland ecosystem in the agro-pastoral ecotone is jointly limited by nitrogen and water.
