摘 要：Soil health depletion due to intensive tillage operations is a global issue in the agricultural *** tillage(CT)which involves non-inversion tillage and leaving~30%of the soil surface covered with crop residues,is a strategy designed to enhance soil ***,no comprehensive study to investigate the long-term effect of CT on soil biological activity and the soil nutrient supply has yet been widely carried *** and chemical soil properties were assessed at depths 0-5,10-15,and 20-25 cm depths after 18 years of CT and conventional tillage practice(PT).Various stages in the vegetative growth of maize were investigated in 2021 in *** findings indicated that tillage intensity,soil depth,and growth stages all significantly influenced soil enzyme activities and the concentration of soil *** soil disturbance resulted in a significantly larger concentration of soil carbon parameters(total organic carbon and labile carbon)in CT plots,where the activity ofβ-glucosidase and dehydrogenase(DHA)in the upper soil layer increased significantly(0.7-2.6 and 2.6-4.7 times,respectively)compared to *** high amount of organic matter and the greater resistance to erosion observed in CT also contributed to the higher concentration of available nutrients(NH_(4),NO_(3),Ca,K)and total P in the surface soil *** activity was highest in the mid-stage of vegetative growth and was positively correlated to the total P *** alterations in soil water content were clearly negatively corelated with the change in DHA and phosphatase ***,due to the more balanced environmental conditions,the decomposition of organic substances was more balanced and slower in CT than in *** implied that the mobilization of nutrients in the soil was more balanced as well,and that the nutrients were released *** enhancement of the soil nutrient-supplying capacity achieved by means of long-term conservation tillage provid
