为了验证生物质灰土壤调理剂改良酸性土壤理化性状的效果,在水稻和油菜连作的土壤上开展了两季定位小区试验。结果表明,生物质灰土壤调理剂不仅可有效改善酸性土壤理化性状(土壤pH提高0.9,土壤阳离子交换量提高0.5 cmol/kg,硅铝率提高0.24),而且具有明显的增产效果。
In order to verify the effect of biomass ash soil conditioner on improving the physical and chemical properties of acid soil, a two-season fixed site plot experiment is carried out on the soil for continuous cropping of rice and rape. The results show that the biomass ash soil conditioner can not only effectively improve the physical and chemical properties of acid soil (soil pH increases by 0.9, soil cation exchange capacity increases by 0.5 cmol/kg, silicon aluminum rate increases by 0.24), but also has a significant yield increase effect.
