Biochar has been widely applied as an efficiency soil additive to modify the quality of cultivated field. However, the effects of long-term biochar addition on spatial and temporal dynamics of soil compaction, and the changes in soil moisture condition and plant root growth remain unclear. Hence, an eight-year (2015/16–2023/24) consecutive field experiment on wheat was conducted in the subtropical humid region of east China, using three treatments: no N fertilizer (PK), chemical fertilizer (NPK), NPK plus biochar (5 t ha⁻¹ yr⁻¹, NPKB). Relative to NPK, across nine growing seasons of wheat, NPKB decreased the soil bulk density by 0.019 and 0.013 units (g cm⁻³ yr⁻¹), and decreased the soil penetration resistance by 0.028 and 0.015 units (MPa yr⁻¹) in 0–10 cm and 10–20 cm depths, respectively. Biochar addition improved soil water content from seeding to flowering, increased wheat root distribution during the whole growth period, and enhanced soil N supply capacity by promoting N adsorption, which gave rise to greater biomass and N accumulation and more biomass allocation in grain. As a result, NPKB increased wheat yield by 14.8 %, N recovery efficiency by 55.1 %, and crop water productivity by 14.9 %, relative to NPK, on average across four growing seasons of wheat. Therefore, long-term biochar addition has potential to substantially increase grain yield of post-rice wheat, water productivity, and N recovery efficiency. Hence, for the sustainable intensification cropping in the long-run, successive biochar addition could be a finable management for wheat production on the rainfed Yangtze River Region of China.

生物炭作为一种改良耕地品质的有效土壤添加剂已得到广泛应用。然而，长期添加生物炭对土壤压实的时空动态、土壤水分状况和植物根系生长的影响尚不清楚。为此，在中国东部亚热带湿润地区进行了为期8年（2015/16-2023/24）的小麦连续田间试验，采用无氮肥（PK）、化肥（NPK）、氮磷钾加生物炭（5 t ha - 1 yr - 1， NPKB） 3种处理。与氮磷钾相比，在小麦的9个生长季节，氮磷钾在0-10 cm和10-20 cm深度分别使土壤容重降低0.019和0.013个单位（g cm−3 yr−1），土壤渗透阻力降低0.028和0.015个单位（MPa yr−1）。添加生物炭提高了小麦苗期至开花期土壤水分含量，增加了小麦全生育期根系分布，并通过促进氮素吸附增强了土壤供氮能力，从而增加了小麦生物量和氮素积累，增加了籽粒生物量分配。结果表明，相对于氮磷钾，氮素恢复效率提高14.8% %，作物水分生产力提高14.9% %，小麦四个生长季节的平均产量提高55.1% %。因此，长期添加生物炭具有显著提高稻后小麦籽粒产量、水分生产力和氮素恢复效率的潜力。因此，从长期可持续集约化种植的角度来看，连续添加生物炭可能是中国长江雨养地区小麦生产的一种适宜的管理方法。

Rising temperature promotes the expansion and shift of multiple cropping systems (CS), which increases food production while consuming more water, thereby having a disadvantage on water-scarce areas. But there exists a dearth of research on the quantitative mechanism. Here we used satellite observations combined with topography-based climate modes to analyze the spatial and temporal changes of CS in the Huang–Huai–Hai River Basin during the historical (2001–2022) and future (2050) periods, then quantified its impact on different agricultural water variables based on a grid-cellularized crop growth model. The results show that 43.86 % of the cultivated land (256.5 thousand km²) exhibited an increase in CS over the past 22 years, mainly reflected in the shift from single CS to double CS in the lower reaches of the Yellow River Basin and the Huai River Basin. This change enhanced the crops’ water productivity by 11.7 % while increasing the agricultural water consumption by 15.6 % and reducing the soil water content by 7.2 %. In the future, multiple CS will further expand northward in 2050 with a maximum increasing area of 199.8 thousand km², which will lead to an irrigation water deficit of 20.6 billion m³, approximately equivalent to 2 times the volume of water diverted along the central route of the South-to-North Water Diversion Project. Our results suggest that the planting structure of CS should be rationally arranged for food-water security under global warming especially in the northern regions.

气温上升促进了复种制（CS）的扩大和转变，这增加了粮食产量，同时消耗了更多的水，因此对缺水地区不利。但对其定量机制的研究还很缺乏。本文利用卫星观测资料结合地形气候模式，分析了黄淮海流域历史（2001-2022年）和未来（2050年）CS的时空变化，并基于网格细胞化作物生长模型量化了CS对不同农业用水变量的影响。结果表明：近22 a来，43.86%（ %）的耕地（25.65万km2）的耕地耕地耕地耕地的耕地耕地面积呈现出耕地耕地耕地面积的增加趋势，主要表现为黄河、淮河下游耕地耕地面积由单一耕地面积向双耕地面积的转变；这一变化使作物水分生产力提高了11.7% %，而农业耗水量增加了15.6% %，土壤含水量减少了7.2% %。未来，多个CS将进一步向北扩展，到2050年最大增加面积为19.8万km2，这将导致206亿m3的灌溉亏水量，大约相当于南水北调中线引水量的2倍。研究结果表明，在全球变暖背景下，为保障粮食水安全，特别是北方地区应合理安排玉米种植结构。
