Abstract:
【
Objective 】In order to explore the effects of different organic fertilizers on fresh corn and determine suitable organic fertilizers for different planting needs. 【
Methods 】two varieties of fresh corn were used as the experimental materials and five different types of organic fertilizers were used as treatments. Soil fertility, agronomic traits, yield, and quality were conduct by comprehensive evaluation. 【
Results 】The results showed that the application of different organic fertilizers over two years led to a slow increase followed by a decrease in soil available potassium content, while other nutrient components increased annually. Amino acid organic fertilizer had the highest increase in organic matter content (0.32%), followed by microbial organic fertilizer. Chemical fertilizer had the highest increase in available nitrogen (4.75 mg/kg), available phosphorus (2.24 mg/kg), available potassium (13.55 mg/kg), total nitrogen (119.72 mg/kg), total phosphorus (33.28 mg/kg), and total potassium (1384.18 mg/kg) content, followed by amino acid organic fertilizer. Different organic fertilizers had varying effects on the agronomic traits of fresh corn, with the yield index of seaweed organic fertilizer combined with microbial agents being superior to chemical fertilizer. The nutrient content of amino acid organic fertilizer was generally at a higher level in the organic fertilizer treatments.【
Conclusion 】The results of comprehensive evaluation using membership function method showed that the combination of seaweed organic fertilizer and microbial agents was found to most effectively promote the ability of fresh corn, while amino acid organic fertilizer could maintain high yields while enhancing the nutritional content of fresh corn and soil fertility.
