Abstract
【Objective 】The effects of fertilizer synergist and fertilizers on maize dry matter accumulation and nitrogen nutrient absorption were studied to provide references for downsizing production cost of maize and increasing maize yield. 【Method】In the pot experiment, fertilization amount of N,P and K was 0.368 g/kg, 0.235 and 0.350 g/kg,respectively. There was one conventional fertilizer treatment(T1) and five other treatments(T2-T6). Each treatment was added by two milliliter fertilizer synergist based on conventional fertilizer treatments(F1-F5). The grain, bract and straw were used to measure the maize nutritional ingredient contents,including total N, total P and total K. The nutrient uptake and utilization of maize were calculated. 【 Result 】 Compared with NPK conventional fertilization treat-ment T1, added fertilizer synergist made fresh corn shell weight increase by 12.0 to 17.50 g/pot with the increment ranging from 4.3% to 6.2%. Maize grain weight increased from 3.9% to 6.9%. Compared to the control, the increase range of dry matter accumulation was 4.97%-6.65%. Nitrogen nutrient absorption volume in various corn organs(straw,grain,husk+cob and root)under synergist treatments was superior to that of the control.(straw:20.60%-37.00%;grain :7.20%-13.15%; husk+cob :12.43%-30.94%;root: 3.13%-37.75%). Compared with single chemical fertilizer,nitrogen utilization rate of synergist treatment increased from 5.0% to 7.2%. 【Conclusion】Adding synergist to conventional fertilizer can markedly increase dry matter content and improve nitrogen utilization rate.
