【摘要】 以烟薯25甘薯为试验材料，设置盆栽试验，研究了添加不同配比的黑水虻虫沙和菌糠混合土对甘薯产量与品质产生的影响以及对栽植甘薯土壤性状及营养含量的影响。结果表明，60%土壤+20%黑水虻虫沙+20%菌糠处理甘薯的结薯数、单薯重、分枝数、叶绿素含量等都有明显的增长，土壤孔隙度、有效磷、速效钾和有机质含量均有显著的提高，因而黑水虻虫沙可以作为有机肥使用，并且会对作物生长发育产生积极的影响。根据各项指标综合考虑，以60%土壤+20%黑水虻虫沙+20%菌糠处理效果最佳，在各方面都优于其他处理。更多还原

【Abstract】 Using Yanshu 25 sweet potatoes as experimental materials, this paper conducted a pot experiment to study the effects of mixed soil adding different ratios of black soldier fly waste and mushroom bran on yield and quality of sweet potatoes, as well as the effects on the properties and nutrient content of sweet potato cultivation soil. The results showed that the sweet potato treated with 60% soil+20% black soldier fly waste+20% mushroom bran had a significant increase in the number of tubers, single tuber weight, number of branches and chlorophyll content, as well as the soil porosity, available phosphorus, available potassium, and organic matter content. Therefore, black soldier fly waste could be used as organic fertilizer and had a positive impact on crop growth and development. Based on comprehensive consideration of various indicators, the treatment of 60% soil+20% black soldier fly waste+20% mushroom bran had the best effect and was superior to other treatments in all aspects.更多还原
