| 摘 要： | 通过不同浓度保水剂种子包衣和保水剂大田示范试验,结果表明:在江河源区退化草地恢复与重建中应用高吸水树脂(SAP保水剂),对提高土壤含水量和保墒具有良好的效果;它不仅能促进幼苗生长发育,而且对植物地上部分的分蘖枝和根系分枝有明显的促进作用;同时对提高牧草个体生物量和产草量有明显的效果.试验结果还表明,使用1%～1.5%浓度的种子包衣处理效果最佳. |

| Abstract: | The researches and field experiment were carried on forage seeds coated and dressed with SPA of different concentrations The results showed:SAP application may improve obviously soil water content and water retention capacity of rehabilitated grassland in the source regions of Yangtze and Yellow Rivers SPA application may not only promote seedling growth and development,plant aboveground tiller and root development but also increase individual plant biomass and forage production The results was best if seeds were coated and dressed with 1%~5% concentration of SPA |
| Keywords: | source regions of Yangtze and Yellow Rivers SAP search degraded grassland soil water |
