This technology includes two parts: one is preparing virus-free sweet potato seedlings using specialized probiotics, featuring pollution-free, strong seedlings with short growth cycles, with yield increasing by 31.4% compared to traditional technology; the other is fermenting sweet potato processing waste into probiotic bacterial fertilizer, which can significantly increase soil organic matter and beneficial microorganism content when applied to farmland. Simultaneously reducing fertilizer and pesticide input, it continuously improves soil quality and sweet potato yield, forming a closed loop resource-recycling green production.
