摘要
综合模拟和田间试验 ,比较研究了保水剂在改良土壤结构、保持土壤水分和节水农业生产中的应用 ,分析了保水剂对不同作物效应、保水剂对马铃薯应用效果。研究表明 ,保水剂能有效改善土壤结构 ,提高土壤保水和释水能力 ;能有效促进作物生长、增加作物产量和提高水分利用效率。文中还讨论了保水剂应用的发展趋势和研究方向。
By colligating the methods of simulating indoor experiments and field tests,the authors studied effect of chemical aquasorb on soil amending, water conservation and applied in water saving agriculture,and analyzed the effective results of chemical aquasorb on different crops and in potato culture.The results showed that the chemical aquasorb can improve soil structure,decrease soil evaporation, and raise soil capacity of water conservation and the releasing,and also accelerate crop growth,increase crop yield and water use efficiency.The authors discussed the developing trend of chemical aquasorb, and pointed out the research direction that should be enhanced in future.
