沼液替代不同比例氮肥对轻度盐化潮土土壤性质及小麦产量的影响
Effects of Replacing Nitrogen Fertilizer with Biogas Slurry on Soil Properties and Wheat Yield in Mild Salinized Fluvo-aquic Soil
摘要
Abstract
In order to study the effects of replacing nitrogen fertilizer with biogas slurry on soil properties and wheat yield in salinized fluvo-aquic soil,a field experiment of wheat was carried out on mild salinized flu-vo-aquic soil.Four treatments were set as conventional fertilization(XG),and replacing conventional fertilizer with biogas slurry in proportions of 30％(T30),50％(T50)and 70％(T70).The results showed that com-pared with conventional fertilization,replacing nitrogen fertilizer with biogas sluirry reduced soil pH value by 0.12～0.33 units;significantly increased the contents of soil organic matter,alkali-hydrolyzed nitrogen,availa-ble phosphorus and available potassium by 52.63％～73.51％,42.83％～120.30％,16.82％～75.14％and 15.42％～49.04％,respectively;significantly increased the contents of Ca2+,Mg2+,Na+and Cl-in soil,and the Ca2+and Na+contents increased by 20.15％～60.85％and 7.72％～72.93％,respectively;increased the contents of Cu,Zn,Mn and B and the activities of alkaline phosphatase and sucrase,while the urease activity increased at first and then decreased with the increase of biogas slurry replacing ratio.Replacing nitrogen fertil-izer with biogas slurry increased the proportion of Proteobacteria and Gemmatimonadota,and the T50 treatment was more beneficial to improve the diversity of soil microbial community.Wheat yield in the T30 and T50 treatments were increased by 6.22％and 11.04％compared with XG treatment.By comprehensive analysis,the replacement of nitrogen fertilizer with biogas slurry could significantly improve soil properties and wheat yield,and the replacement ratio of 50％had the best effect.The research results could provide theoretical ref-erences for the application of biogas slurry in mild salinized fluvo-aquic soil.关键词
