保水剂是一类高吸水性树脂,内部含有大量结构特异的强吸水性基团,可吸收自身重量数百倍至上千倍的去离子水,即保水剂具有很强的吸水性和保水性。本文基于在甘肃省祁连山东端华藏林场高寒半干旱生态公益林区进行的造林绿化保水剂应用研究,在不同立地条件及两种当地主要造林树种上进行
Super absorbent polymer is a type of super absorbent resin, which contains a large number of structurally-specific strong water-absorbing groups, which can absorb hundreds of times its own weight to thousands of times the deionized water, that water retaining agent has a strong water absorption and water retention. Based on the application of afforestation and greening water-retaining agent in the alpine semi-arid eco-public forest in the Huaxia Forest Farm at the eastern end of the Qilian Mountains in Gansu Province, this study was conducted on different site conditions and on two main afforestation species
