生物有机肥在西瓜生产化肥减施上的应用效果

Application Effect of Bio-organic Fertilizer on Chemical Fertilizer Reduction in Watermelon Production

[目的]探索西瓜生产中化肥减施措施。[方法]利用农业废弃物木薯酒糟沼渣和菇渣生产的生物有机肥栽培西瓜,设定减施化肥25%和30%2个目标,研究增施生物有机肥对西瓜产量及品质的影响。[结果]化肥减施后,随着生物有机肥施用量的增加,西瓜产量及品质均显著提高,减施化肥25%各处理均优于减施化肥30%处理;化肥减施25%时,施6000和7500 kg/hm^(2)生物有机肥对西瓜产量无显著影响,但施7500 kg/hm^(2)品质略好。[结论]化肥减施25%、施微生物菌肥6000~7500 kg/hm^(2)可显著提高西瓜产量和品质。

[Objective]To explore the measures of reducing chemical fertilizer application in watermelon production.[Method]The effects of bio-organic fertilizer on the yield and quality of watermelon were studied by using bio-organic fertilizer produced by cassava distiller’s grains and mushroom residue from agricultural waste.[Result]The yield and quality of watermelon increased significantly with the increase of bio-organic fertilizer application,and the treatment of 25%fertilizer reduction were better than 30%fertilizer reduction.6000 and 7500 kg/hm^(2) of bio-organic fertilizer had no significant difference on watermelon yield,but the quality of 7500 kg/hm^(2) was slightly better.[Conclusion]The yield and quality of watermelon can be improved significantly by applying 25%fertilizer and 6000-7500 kg/hm^(2) microbial fertilizer.
