Biochar-based fertilizers are used to improve soil's physiochemical and biological properties and increase fertilizer utilization rate. Therefore, a technological model of biochar-based fertilizers is essential for the reduced application. This study was conducted to determine the effects of the different levels of biochar-based fertilizer applications on soil and plant nutrient content, as well as maize yield. Biochar-based fertilizer increased the total N content of maize stem and kernel and the total P content of maize axis and kernel. Biochar-based fertilizer increased the total P but decreased the total K of maize plants while increasing the fertilizer's partial productivity. Treatment B1 (600.00 kg hm of biochar-based fertilizer) increased the dry-matter weight of the maize at silking and filling stages by 1.60 and 15.83%. Treatment B1 increased the ear length, diameter, and plant height. Compared with BCK (600.00 kg hm of conventional fertilizer), the yield of B1 was increased by 9.23%, and the difference was significant ( < 0.05). Biochar-based fertilizer treatments B2-B5 (biochar-based fertilizer reduced by 5-20%) reduced maize yield, but there was no significant difference between their yield and BCK. This study aimed to provide a basic understanding and reference for maize fertilizer reduction with good application prospects.
生物炭基肥料用于改善土壤的物理化学和生物学性质，并提高肥料利用率。因此，生物炭基肥料的技术模型对于减少施肥量至关重要。本研究旨在确定不同施用量的生物炭基肥料对土壤和植物养分含量以及玉米产量的影响。生物炭基肥料增加了玉米茎和籽粒的全氮含量以及玉米轴和籽粒的全磷含量。生物炭基肥料增加了玉米植株的全磷含量，但降低了全钾含量，同时提高了肥料的偏生产力。处理B1（600.00 kg·hm生物炭基肥料）使玉米在抽丝期和灌浆期的干物质重量分别增加了1.60%和15.83%。处理B1增加了玉米穗长、穗径和株高。与BCK（600.00 kg·hm传统肥料）相比，B1的产量提高了9.23%，差异显著（<0.05）。生物炭基肥料处理B2-B5（生物炭基肥料减少5%-20%）降低了玉米产量，但其产量与BCK之间无显著差异。本研究旨在为具有良好应用前景的玉米减施肥料提供基本认识和参考。
