新型多孔改良剂增强黄壤通气性能研究
|
摘要
为探索新型多孔改良剂对黄壤通气性能的影响,本文以贵州省毕节市植烟黄壤为研究对象,通过掺入不同比例的新型多孔改良剂,研究贵州黏重黄壤物理结构的变化。结果表明:随着添加新型多孔改良剂比例的增加,土壤总孔隙度及土壤通气孔隙度均随之增加。与对照相比,3个处理(新型多孔改良剂添加比例分别为7.5%、15.0%和22.5%)的总孔隙度分别增加了2.7%、3.1%和3.2%,通气孔隙度分别增加了2.7%、8.6%和10.6%;对照和3个处理加水饱和之后,分别需要130、52、34和37 h提供足够的氧气,以保证作物正常生长。总之,新型多孔改良剂能够有效增加黏重黄壤通气孔隙,达到了增强土壤通气性能的目的,为黏重土壤改良提供了新的途径与思路。
In order to study the effects of novel porous amendments on improving aeration of clayey yellow soil, an experiment was conducted in Bijie of Guizhou by adding different proportions of amendments to soil, and then soil porosity and aeration porosity were measured. The results showed that soil porosity and aeration porosity were increased with the increase of the proportion of novel porous amendments. Compared with CK, soil total porosities under 7.5%, 15.0% and 22.5%amendment-adding treatments increased by 2.7%, 3.1% and 3.2%, respectively, and soil aeration porosities increased by 2.7%,8.6% and 10.6%, respectively. After the water saturation, 130 h, 52 h, 34 h and 37 h were required to provide oxygen enough to ensure the growth of the crops for CK and three amendment-adding treatments, respectively. It shows that the novel porous amendments can effectively increase soil porosity and improve soil aeration of clayey yellow soil, thus, is a new way to improve clayey soil.
