[Objectives] This study was conducted to clarify the effects of bacteria-enzyme compound preparations and their application methods on rice yield, yield components, growth at the maturation stage, soil nutrients, and economic benefits. [Methods] The medium-late maturing japonica rice variety Runnong 303 was used as the test material, and a field experiment was conducted in Laixi City, Shandong Province. Based on equal amounts of conventional fertilization, three treatments were set up: conventional fertilization (CK), conventional fertilization + one application of compound enzyme preparation at the sowing stage (base fertilizer) (T1), and conventional fertilization + one application of compound enzyme preparation during the basal fertilization+ seven foliar sprays of microbial agent at 10-15 d intervals during the growth period (T2). [Results] The application of the bacteria-enzyme compound preparation significantly increased rice yield, and the effect was enhanced with the application frequency of the microbial agent increasing. The actual yields of T1 and T2 were significantly increased by 11.61% and 27.42%, respectively, compared with the CK, and the yield increase was mainly attributed to the significant increase in the number of grains per panicle. At the maturation stage, the plant height, basal stem diameter, leaf width, and leaf length of T1 and T2 were all significantly greater than those of the CK. At harvest, soil nutrients were significantly improved with the application frequency of the microbial agent increasing. Based on the assumed prices, the net economic benefits of T1 and T2 were increased by 2 626.5 and 4 057.5 yuan/hm², respectively, compared with the CK, and the marginal output-input ratios were 8.96 and 2.54, respectively. In summary, the application of the bacteria-enzyme compound preparation can significantly increase rice yield, improve soil nutrients, and enhance planting economic benefits. Multiple applications of the microbial agent throughout the entire growth period (T2) achieved the greatest total increases in yield, soil fertility, and income, while a single application at the sowing stage (T1) exhibited the highest input-output efficiency. The corresponding application method can be selected according to production objectives. [Conclusions] This study provides a theoretical basis for the scientific and efficient application of bacteria-enzyme compound preparations. |
