Effects of Straw Incorporation and Phosphorus Fertilization on Photosynthetic Characteristics, Dry Matter Accumulation, and Grain Yield of Maize
Maize (Zea mays L.) is a major cash and food crop in China and is critical to national food security. Straw returning improves soil physical properties by reducing bulk density and increasing porosity, while phosphate fertilization enhances soil P availability; their combined application can improve soil fertility and...
