Abstract

Wide-precision planting has been introduced to wheat production systems in China to improve grain yield. However, the effects of wide-precision planting on wheat yield, nitrogen (N) use efficiency (NUE), and water productivity (WP) have not yet been comprehensively evaluated. A meta-analysis was conducted using 699 observations from 79 studies to quantify the contributions of wide-precision planting to wheat yield, NUE, and WP. Compared with conventional-cultivation planting, wide-precision planting increased wheat yield by 9.9 %, NUE by 9.3 %, and WP by 4.8 %. Soil conditions had the greatest importance on wheat yield, NUE, and WP under wide-precision planting, particularly suitable soil organic matter and available potassium. Fertilizer factors also influenced the wheat's comprehensive productivity under wide-precision planting. The random forest regression model revealed that more attention should be paid to the application of potassium and phosphorus fertilizers in wheat production. Additionally, wide-precision planting under high mean annual precipitation (> 600 mm) and medium mean annual temperature (10–13℃) more easily coordinated improvements in yield, NUE and WP. In conclusion, wide-precision planting can significantly increase wheat comprehensive productivity. Considering the factors of climate, soil fertility and different fertilizers, the study holds novel insights for informing the widespread adoption of wide-precision planting practices in wheat production.

广泛精准种植提高中国冬小麦产量、氮素利用效率和水分生产力：一项荟萃分析

为了提高粮食产量，中国在小麦生产系统中引入了广泛的精准种植。然而，广泛精密种植对小麦产量、氮素利用效率（NUE）和水分生产力（WP）的影响尚未得到全面评价。对79项研究的699项观察结果进行了荟萃分析，以量化宽精度种植对小麦产量、氮肥利用效率和WP的贡献。与常规种植相比，宽精种植小麦产量提高9.9% %，氮肥利用率提高9.3% %，WP提高4.8% %。土壤条件对宽精密度种植下小麦产量、氮肥利用效率和WP的影响最大，尤其是适宜的土壤有机质和速效钾。施肥因素对宽精种植条件下小麦的综合生产能力也有影响。随机森林回归模型表明，在小麦生产中应重视钾肥和磷肥的施用。此外，在高平均年降水量（>； 600 mm）和中等年平均温度（10-13℃）条件下，宽精度种植更容易协调产量、氮肥利用效率和WP的提高。综上所述，宽精密度种植能显著提高小麦综合生产力。考虑到气候、土壤肥力和不同肥料的因素，该研究为在小麦生产中广泛采用高精度种植实践提供了新的见解。
