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%。

Abstract

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 diamenters ters of KSAP were added to the soil

whereas the frequency of irrigation on water preservation of KASP was not significant. The effectivewater in sand

red soil

and brown soi1 were increased by 32.7%

18.1%and 24.3%

respectively

when KSAP(0.30%

particle diameter 0.80mm) was sprayed to surface.
