摘  要:
通过室内模拟试验,利用析因设计法研究了魔芋超强吸水剂(KSAP)对土壤保水性能的影响。结果表明,魔芋超强吸水剂的施入方式、用量、粒径对不同类型土壤保水性能影响达到高度显著水平(P<0.01);浇水频率对魔芋超强吸水剂的保水性能影响不显著。魔芋超强吸水剂用量0.30%,粒径0.80mm,以表层喷洒的方式分别加入沙、红壤和棕壤中,沙的有效含水量增加32.7%,红壤的有效含水量增加18.1%,棕壤的有效含水量增加24.3%。

摘  要:
By the laboratory experiments, the effects of konjac super absorbent polymer(KSAP)on water preservation in soil were studied using factorial designed experiment. Results showed that the effects of soil water preservation were significant (P<0.01) when different additions, different dosages and particle diameters of KSAP were added to the soil, whereas the frequency of irrigation on water preservation of KSAP was not significant. The effective water in sand, red soil, and brown soil were increased by 32.7 %, 18.1%, and 24.3%, respectively, when KSAP (0.30 %, particle diameter 0.80mm) was sprayed to surface.
