Abstract: 【Objective】To investigate the effects of castor cake meal fertilizer on soil nutrients and enzyme activities in Cerasus humilis,providing a novel fertilization strategy for its cultivation.【Methods】Using the Cerasus humilis cultivar Jing'ou as the experimental material,a randomized block design was employed with no fertilization as the control(CK)and treatments including chemical fertilizer(F),cattle manure(N),and castor cake meal fertilizer(B1,B2,B3,B4). The effects of these treatments on soil nutrients and enzyme activities were analyzed.【Results】Compared with CK,soil pH value in treatments B1,B2,and B3 significantly decreased by 2.1%,3.4%,and 1.2%,respectively,and was significantly lower than in treatments N and F(P<0.05). Soil organic matter content in treatments B2 and B4 increased by 19.2% and 16.8%,respectively,compared with CK. Soil total nitrogen content in treatments B2,B3,and B4 was significantly higher than in treatments F and N by 17.3%-24.8% and 4.4%-11.0%,respectively(P<0.05). Soil total phosphorus content in treatment B3 was significantly higher than in treatments F and N by 20.7% and 14.7%,respectively(P<0.05). Soil alkali-hydrolyzable nitrogen content in treatments B1,B2,and B4 increased by 22.4%-39.4% and 2.0%-16.2% compared with treatments F and N,respectively. Soil alkaline phosphorus content in treatments B1,B2,B3,and B4 was significantly higher than in treatments F and N by 26.7%-193.4% and 15.4%-163.2%,respectively(P<0.05). Soil available potassium content in treatments B1,B2,B3,and B4 increased by 12.7%-60.6% and 15.9%-65.2% compared with treatments F and N,respectively. Application of castor cake meal fertilizer significantly enhanced the activities of soil urease,acid phosphatase,acid protease,acid invertase,sucrase,N-acetylglucosaminidase,and leucine aminopeptidase,while reducing soil nitrate reductase activity. Pearson correlation analysis revealed varying degrees of correlation between soil nutrients and enzyme activities.【Conclusion】The application of castor cake meal fertilizer improved the physicochemical properties of Cerasus humilis soil. Compared with chemical fertilizer and cattle manure,castor cake meal fertilizer effectively regulated soil pH value,increased soil nutrient content,and enhanced soil enzyme activity to varying extents.
