基于玉米秸秆乙酸法制浆废液的土壤改良剂研究
Study on the Use of Waste Liquid from Corn Straw Acetic Acid Pulping as Soil Conditioners
摘要
Abstract
In this study,the waste liquid from acetic acid pulping of corn straw(referred to as degradation liquid)was used.Through potting experiments,the effects of different dilution ratios(25～200 times)of degradation liquid on soil physicochemical properties,enzyme activi-ties,and the growth of leafy vegetable plants were explored.The results showed that the degradation liquid contained various components such as sugars and small molecule organic acids.The application of degradation solution could increase the content of soil organic matter,decrease the pH value,increase the electrical conductivity,and enhance the activities of sucrase and phosphatase.When the dilution ratio was greater than 100 times,the soil bulk density decreased,the water content increased,the contents of total phosphorus and available phos-phorus both increased,and the activities of urease and catalase both decreased.When the dilution ratio was greater than 50 times,the con-tent of ammonium nitrogen of soil increased.Degradation solutions diluted 50 to 200 times could all promote plant growth,among which the plants treated with degradation solution diluted 100 times had the best growth.In conclusion,the entire component of the waste liquid from acetic acid pulping of corn stalks could be used to improve soil quality.The degradation liquid at an appropriate concentration could effec-tively enhance the physical properties,chemical fertility,and biological fertility of the soil,and promote the growth of crops.关键词
