Abstract

Ridge–furrow cropping patterns, nitrogen fertilisation and seed rate regulation are popular management strategies for improving crop yields in the semi-arid areas of Northwest China, but their interactive effects on grain yield and water use efficiency remain poorly understood. In 2020–2021 and 2021–2022, a two-season field experiment was conducted on winter wheat. There were two cropping patterns (C), ridge–furrow cropping with film mulch (RC) and traditional cropping without mulch (TC), two nitrogen fertilisation rates (N), 0 and 200 kg N ha⁻¹ (N₀ and N₁) and three seed rates (S), 240, 360 and 480 plants m⁻² (S₁, S₂ and S₃). The study was conducted in a split–split design with three replications (randomised blocks) and a total of 24 experimental plots. It was found that the interactive effects of C × N, C × S and N × S were significant on soil temperature (ST), leaf area index (LAI), relative chlorophyll content (SPAD), photosynthetic parameters, grain yield (GY) and water use efficiency (WUE) (p < 0.05), while C × N × S was significant only for LAI, aboveground biomass (AGB), GY and WUE (p < 0.05). Compared with TC and N₀, RC and N₁ significantly increased SPAD value (2.4% and 15.8%), net photosynthetic rate (P_n) (19.8% and 32.8%), net photosynthetic rate (P_n), transpiration rate (T_r) (7.0% and 15.7%) and the effective PSII quantum production (ΦPSII) (10.7% and 5.0%). The highest GY (6773 kg ha⁻¹ over 2020–2021 and 8036 kg ha⁻¹ over 2021–2022) and WUE (20.03 kg ha⁻¹ mm⁻¹ over 2020–2021, and 21.77 kg ha⁻¹ mm⁻¹ over 2021–2022) of winter wheat were observed under RC + N₁ + S₂. The findings showed that the RC cropping pattern with fertilisation and seed rate regulation (360 plants m⁻²) of winter wheat, which is appropriate for ensuring the long-term sustainability of agricultural production in the semi-arid regions of Northwest China, enhanced plant growth, photosynthetic traits, yield and water use efficiency. The study might give useful information for enhancing the productivity and water use efficiency of winter wheat in this and other similar climate locations.

氮肥施用和种子率调节提高了垄作冬小麦（Triticum aestivum L.）的光合作用、籽粒产量和水分利用效率

垄作模式、氮肥施用和播种量调节是西北半干旱地区提高作物产量的常用管理策略，但它们对粮食产量和水分利用效率的交互影响仍鲜为人知。2020-2021 年和 2021-2022 年，对冬小麦进行了两季田间试验。试验采用两种种植模式（C）：覆膜脊耙种植（RC）和无覆膜传统种植（TC）；两种氮肥施用量（N）：0 和 200 kg N ha-1（N0 和 N1）；三种播种量（S）：240、360 和 480 株 m-2（S1、S2 和 S3）。研究采用了三重复（随机区组）、共 24 块试验田的分割设计。研究发现，C × N、C × S 和 N × S 的交互效应对土壤温度（ST）、叶面积指数（LAI）、相对叶绿素含量（SPAD）、光合参数、谷物产量（GY）和水分利用效率（WUE）有显著影响（p < 0.05），而 C × N × S 仅对 LAI、地上生物量（AGB）、GY 和 WUE 有显著影响（p < 0.05）。与 TC 和 N0 相比，RC 和 N1 显著提高了 SPAD 值（2.4% 和 15.8%）、净光合速率（Pn）（19.8% 和 32.8%）、净光合速率（Pn）、蒸腾速率（Tr）（7.0% 和 15.7%）和 PSII 有效量子产量（ΦPSII）（10.7% 和 5.0%）。在 RC + N1 + S2 条件下，冬小麦的 GY（2020-2021 年为 6773 千克/公顷-1，2021-2022 年为 8036 千克/公顷-1）和 WUE（2020-2021 年为 20.03 千克/公顷-1 毫米-1，2021-2022 年为 21.77 千克/公顷-1 毫米-1）最高。研究结果表明，冬小麦施肥和播种量调控（360 株/米-2）的 RC 种植模式可提高植株生长、光合性状、产量和水分利用效率，适合于确保西北半干旱地区农业生产的长期可持续性。该研究可为提高该地区及其他类似气候条件下冬小麦的产量和水分利用效率提供有用信息。

期刊介绍： The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
