浒苔发酵液及其复合液剂对土壤性质和酶活性的影响
Influence of Enteromorpha prolifera Fermentation Liquid and Its Composite Liquid on Soil Properties and Enzyme Activities
摘要: 为探讨海藻生物肥对土壤性质及酶活性的影响，本文以浒苔发酵液及其复合液在番茄种植土壤施用后，不同处理组间土壤性质及酶活性进行了比较研究。试验结果表明：T1 (浒苔发酵液)的pH值最低，较未处理前下降10.95%；T4 (浒苔–菊花复合液)处理下的土壤脲酶酶活性最高，较空白对照组显著提高58.82%；T3 (浒苔–金银花复合液)处理下的蔗糖酶酶活性最高，较空白对照组提高6.13%；T3 (浒苔–金银花复合液)处理下的土壤磷酸酶酶活性最高，较空白对照组显著提高13.44%。综上，浒苔发酵液及其复合液能够降低土壤的pH值，促进植株对有机质的吸收，提高土壤中脲酶、蔗糖酶、磷酸酶的活性，有利于改善土壤肥效转化的微生态环境。
Abstract: In order to explore the effect of seaweed biofertiliser on soil properties and enzyme activities, this paper conducted a comparative study of soil properties and enzyme activities between different treatments after the application of Enteromorpha prolifera fermentation liquid and its composite liquid in tomato planting soil. The test results showed that: T1 (Enteromorpha prolifera fermentation liquid) had the lowest pH value, which decreased by 10.95% compared to that before untreated; T4 (Enteromorpha prolifera-chrysanthemum composite liquid) had the highest soil urease enzyme activity under the treatment, which was significantly increased by 58.82% compared to that of the blank control group; T3 (Enteromorpha prolifera-honeysuckle composite liquid) had the highest sucrase enzyme activity under the treatment, which was increased by 6.13% compared to that of the blank control group; T3 (Enteromorpha prolifera-honeysuckle composite liquid) had the phosphatase enzyme activity was the highest, which was significantly increased by 13.44% compared to the blank control group. In conclusion, the Enteromorpha prolifera fermentation liquid and its compound liquid can reduce the soil PH, promote the absorption of organic matter by plants, improve the activities of urease, sucrase and phosphatase in soil, and help to improve the soil microbiological environment of soil fertility transformation.
