1、 No-tillage with total green manure (GM) mulching (NTG) can optimize maize root structure by improving soil water content (SWC) and soil temperature (ST) environment. 2、 NTG increased maize photosynthetic capacity and grain yield (GY). 3、 The relationship between SWC, ST, root length (RL), photosynthetic characteristics and GY was expounded. Wheat-maize rotation is a widely used planting pattern in oasis irrigated areas in northwest China. Although this planting pattern has the advantage of breaking the barrier of continuous cropping to some extent, it also has some problems such as large evaporation and prominent soil degradation during fallow period, which seriously restricts the improvement of crop yield. Planting green manure (GM) after wheat and returning it to field can effectively improve soil physicochemical properties, regulate photosynthetic characteristics of subsequent crops and promote crop yield. However, the photosynthetic physiological mechanism of crop yield improvement under different green manure return methods (GMRM) is still unclear. Therefore, by exploring the relationships among soil moisture and temperature environment, maize root structure, photosynthetic characteristics, fluorescence characteristics and yield under different GMRM, this study aims to provide theoretical basis for clarifying the photosynthetic physiological mechanism of GMRM to improve maize yield. A three-year field experiment was conducted at a research station in the Shiyang River...
