| 摘 要： | WOTE保水剂(SAP)施用45kg/hm2能够提高作物产量,提高壤砂土样地的田间持水量、降低土壤容重,具有理想的应用效果。施用1a-5a可以提高胡萝卜的出苗率10%-26.25%,增产18.71%-33.09%,其中第4a的产量增加最大。SAP改良土壤物理性质的作用具有周期性。1a-5a容重降低5.24%-14.3%,第3a降低最明显为14.3%。田间持水量第2a提高13.59%,为5a中最大,第4a、5a效果不显著。1次施用后,对土壤物理性质以及胡萝卜生长的调节作用可以持续3a,第5a各种测试指标都呈下降趋势。SAP施用深度在10cm,增加了土壤通透性,减小了上下层土壤的水势差,提高了土壤自身的渗水、保水能力。 |
