Abstract

This study examined the effect of study time, biochar dose, and fertilization-tillage system on the improvement of sandy loam physical-chemical properties and triticale grain yield. The soil properties (water holding capacity (WHC), wettability, moisture content (MC), organic matter content (SOM), pH, and electrical conductivity (EC) were monitored in short time intervals (after 3, 6, 12, and 24 months). Soil was tilled in two methods (shallow ploughless tillage and direct drilling), fertilized with nitrogen, phosphorus, and potassium (NPK) fertilizers, and amended with three hydrophobic pine wood biochar doses (0 t/ha; 5 t/ha; 15 t/ha). It was found that 15 t/ha biochar dose had the highest effect on the soil's physical-chemical properties improvement (SOM increased by 33.7%, pH-by 6.84%, EC-by 23.4%, WHC-by 8.48%, and MC-by 21.8%) compared to the variants without biochar. Direct drilling, fertilization with NPK fertilizers and 15 t/ha biochar dose significantly influenced the rise of soil's physical-chemical properties and triticale yield (3.51 t/ha).

摘要

本研究考察了学习时间、生物炭剂量和施肥-耕作制度对砂壤土理化性质改善及小黑麦籽粒产量的影响。在短时间间隔（3、6、12和24个月后）监测土壤性质（持水量（WHC）、润湿性、含水量（MC）、有机质含量（SOM）、pH值和电导率（EC））。土壤采用两种方法耕作（浅免耕和直播），施用氮、磷、钾（NPK）肥料，并用三种疏水性松木生物炭剂量（0吨/公顷；5吨/公顷；15吨/公顷）进行改良。结果发现，与不使用生物炭的变体相比，15吨/公顷的生物炭剂量对土壤理化性质的改善效果最佳（SOM增加33.7%，pH值增加6.84%，EC增加23.4%，WHC增加8.48%，MC增加21.8%）。直播、施用NPK肥料和15吨/公顷的生物炭剂量显著影响了土壤理化性质的提高和小黑麦产量（3.51吨/公顷）。
