Abstract: [Objectives] To study the impacts and demonstration effects of long-acting slow-release fertilizer application on economic yield of peanut. [Methods] The 25, 30, 35, 40, 45, 50 kg of long-acting slow-release fertilizers were applied to 667 m2 of peanuts, and different amounts of urea were applied together. [Results] Applying 40 kg of long-acting slow-release fertilizer and 10.45 kg of urea had the best effect. Compared with the application of ordinary compound fertilizers, the plants did not age prematurely, the leaf diseases were mild, the stems and leaves remained dark green when harvested, and the stems and leaves had a longer functional period. Bearing shoots increased by 1.7, single-plant full pods increased by 2.4, double-seed peanuts increased by 3.2, empty pods decreased by 0.5, and single-seed peanuts decreased by 0.7. The experimental demonstration results show that the spring-sowed peanuts had an average yield increase of 29.0-67.2 kg/667 m2, and the yield increase rate was 7.35%-16.89%, and the difference was extremely significant. [Conclusions] In the high-yield cultivation of peanuts, the application of long-acting slow-release fertilizer can be promoted to improve peanut production.
