Abstract

High temperature is known to reduce crop yield, while increased nitrogen (N) application will increase crop grain and protein yields to a certain extent. However, there are few studies on the effects of different N application treatments on crop yield and protein under climate warming in different wheat-maize rotation cultivation sites. Therefore, by utilizing the APSIM model, we investigated crop yield, yield components, grain N contents, and biomass N content across 71 key sites of wheat-maize rotation cultivation systems in China. Four N treatments of 0, 90, 180 and 270 kg N ha–1 (N0, N90, N180 and N270) were applied before sowing in both wheat and maize seasons. The APSIM model was calibrated and validated using data of yield and grain N content. We predicted regional differences in crop yield and grain N content under a warming 2°C scenario. There were regional differences in the effects of increased N application treatments and warming 2°C on wheat and maize yields, yield components and grain N contents. Increased N application improved maize 1000-grain weight and wheat grain number, and consequently affected crop yield and grain N content but reduced N translocation from plants to grains (NHI), especially in areas with more precipitation in wheat season and higher temperature in maize season. Warming shortened the duration of the reproductive growth period in maize by 6.2–9.5 d but lengthened it in wheat by 9.1–16.5 d. Furthermore, warming reduced maize yield mainly by decreasing maize 1000-grain weight and improved wheat yield mainly by increasing 1000-grain weight. Warming improved wheat grain N content and NHI under different N application treatments, especially in Shandong, Guanzhong, and Henan regions (0.86–1.98 kg ha–1 and 0.01–0.27, respectively). However, warming reduced maize yield, grain N content and NHI by 4.1 %–10.9 %, 1.5 %–6.8 % and 0.7 %–6.1 %, respectively, under different N application treatments except in Guanzhong. Additionally, increasing N application rate could alleviate the negative effects of warming on maize yield and grain protein production. In 2050–2067 maintaining historical plantation area, the regional total maize protein supply population was projected to reduce by 962.17 and 388.95 million people under N application of N180 and N270 kg N ha–1, respectively, compared with 2000–2017. The findings would provide scientific basis for N management strategies in wheat-maize rotation planting areas of China under climate warming.

预计增加氮的施用量可减轻气候变暖对玉米减产的影响,并维持小麦和玉米蛋白质的膳食供应
众所周知,高温会降低作物产量,而增加氮肥施用量则会在一定程度上提高作物籽粒和蛋白质产量。然而,关于气候变暖条件下不同施氮处理对不同小麦-玉米轮作种植地作物产量和蛋白质影响的研究很少。因此,我们利用 APSIM 模型研究了中国 71 个小麦-玉米轮作栽培系统关键点的作物产量、产量组成、籽粒氮含量和生物质氮含量。在小麦和玉米两季播种前施用 0、90、180 和 270 kg N ha-1 四种氮处理(N0、N90、N180 和 N270)。利用产量和谷物氮含量数据对 APSIM 模型进行了校准和验证。我们预测了在升温 2°C 情景下作物产量和谷物氮含量的地区差异。增加氮肥施用量处理和升温 2°C 对小麦和玉米产量、产量成分和谷物氮含量的影响存在地区差异。增施氮肥提高了玉米千粒重和小麦粒数,从而影响了作物产量和籽粒含氮量,但减少了氮从植物向籽粒的转化(NHI),尤其是在小麦季降水较多和玉米季气温较高的地区。气候变暖使玉米生殖生长期缩短了 6.2-9.5 d,但小麦生殖生长期延长了 9.1-16.5 d。此外,气候变暖主要通过降低玉米千粒重来减少玉米产量,而主要通过增加小麦千粒重来提高小麦产量。在不同施氮处理条件下,增温提高了小麦籽粒氮含量和净海拔指数,尤其是在山东、关中和河南地区(分别为 0.86-1.98 kg ha-1 和 0.01-0.27)。然而,除关中地区外,在不同氮肥施用处理下,升温会使玉米产量、籽粒含氮量和NHI分别降低4.1%-10.9%、1.5%-6.8%和0.7%-6.1%。此外,增加氮肥施用量可减轻气候变暖对玉米产量和籽粒蛋白产量的负面影响。在 2050-2067 年保持历史种植面积的情况下,与 2000-2017 年相比,施氮量分别为 N180 和 N270 千克/公顷时,区域玉米蛋白供应总人口预计将分别减少 9.6217 亿人和 3.8895 亿人。研究结果将为气候变暖条件下中国小麦-玉米轮作种植区的氮管理策略提供科学依据。

期刊介绍: The European Journal of Agronomy, the official journal of the European Society for Agronomy, publishes original research papers reporting experimental and theoretical contributions to field-based agronomy and crop science. The journal will consider research at the field level for agricultural, horticultural and tree crops, that uses comprehensive and explanatory approaches. The EJA covers the following topics: crop physiology crop production and management including irrigation, fertilization and soil management agroclimatology and modelling plant-soil relationships crop quality and post-harvest physiology farming and cropping systems agroecosystems and the environment crop-weed interactions and management organic farming horticultural crops papers from the European Society for Agronomy bi-annual meetings In determining the suitability of submitted articles for publication, particular scrutiny is placed on the degree of novelty and significance of the research and the extent to which it adds to existing knowledge in agronomy.
