摘要
针对红壤退化区肥力低下,保肥保水能力弱的现状,本研究利用项目组研制的复合微生物肥料,探讨其在改善红壤裸土区土壤物理化和生物学特征的调理作用.试验表明,施用复合微生物肥料有效改善土壤物理特性,减轻土壤酸化问题,显著提高有机质、有效磷、有效钾和有效硼的含量,促进植物促生菌Haliangium、纤维素降解菌的繁殖,抑制引起氮素散失的菌群的生长,从而提高肥料利用率.因此,该复合微生物肥料可作为一种提高红壤退化区土壤肥力,减少水土流失的新产品进行推广.
Abstract
Aiming at the current situation of low fertility and weak capacity of water storage and fertility retention in the red soil degradation area,by the application of compound microbial fertilizer developed by the project team,it was discussed the conditioning effect on improving the physical,chemical,and biological characteristics of red soil in bare soil areas.The results show that,application of the compound microbial fertilizer may effectively improves the physical characteristics of soil,reduces the problem of soil acidification,significantly improves the contents of organic matter,effective phosphorus,effective potassium and effective boron,accelerate the reproduction of Haliangium of plant life-promoting bacteria and cellulose-degrading bacteria,while inhibits the growth of bacteria causing nitrogen loss,so as to improve the utilization rate of fertilizer.Therefore,the compound microbial fertilizer can be promoted as a new product to control soil erosion in red soil degradation areas.
