- Abstract
【Objective】 The objective of this project is to study the effects of different levels of biological bacterial fertilizer on leaf area, aboveground biomass, photosynthetic rate and yield of foxtail millet.【Methods】 Jinpingu 4 was used as the experimental material, 6 fertilization levels were set up: 0 (CK), 450 (S1), 900 (S2), 1,350 (S3), 1,800 (S4) and 2,250 (S5) kg/hm² in the field, with randomized block design and 3 replicates.【Results】 Leaf area of fertilization treatment in anthesis stage was significantly higher than that of CK, and the leaf area of S4 was the largest, 203.03 cm² and 14.53% higher than that of CK; the aboveground fresh and dry weight of foxtail millet in anthesis stage was the largest, 579.46 g and 153.02 g, respectively, and was significantly higher than that of other treatments; the photosynthetic rate of S4 was the highest in heading stage, anthesis stage and filling stage, 26.29, 22.94 and 14.02 μmol/(m²·s²), the photosynthetic rate increased first and then decreased with the increase of fertilization level, and different fertilization treatments were significantly higher than that of CK; the yield of different fertilization treatments was significantly higher than that of CK, and with the increase of fertilization, the yield increased to a certain peak and decreased, the yield of S4 was the highest, 4,995.00 kg/hm², 17.80% higher than that of CK.【Conclusion】 As an environmental friendly fertilizer, biological bacterial fertilizer can replace part of inorganic fertilizer, and the suitable level is 1,800 kg/hm².
