In this study, the emergence rate, emergence potential, root length, stem length, water consumption, and biomass around a root system were used as evaluation indexes, and we used the laboratory-prepared super absorbent resin watermelon rind (WMR)-p (AA--DAAM) (superabsorbent polymer 1-SAP), WMR-p (AA--DAAM)/palygorskite (PGS) (SAP) in a laboratory and commercially available water-retaining agents (SAP and SAP) to assist the emergence of seeds and seedling growth; then, their water absorption and thermal stability were discussed. The results showed that the thermal stability of an SAP prepared in the laboratory and the water consumption during seed emergence, root length, and stem length after emergence were better than those of an SAP purchased on the market, and this information could help to promote the emergence and seedling growth of . While enhancing the drought resistance of plants, using a laboratory-produced SAP can effectively reduce the number of artificial irrigations.
在本研究中,将根系周围的出苗率、出苗势、根长、茎长、耗水量和生物量作为评价指标,在实验室中使用自制的超吸水性树脂西瓜皮(WMR)-p(AA--DAAM)(高吸水性聚合物1-SAP)、WMR-p(AA--DAAM)/坡缕石(PGS)(SAP)以及市售保水剂(SAP和SAP)来辅助种子出苗和幼苗生长;然后,对它们的吸水性和热稳定性进行了探讨。结果表明,实验室制备的SAP的热稳定性以及种子出苗期间的耗水量、出苗后的根长和茎长均优于市售的SAP,这些信息有助于促进种子出苗和幼苗生长。在增强植物抗旱性的同时,使用实验室生产的SAP可以有效减少人工灌溉次数。
