Abstract:

In order to clarify the influence of different sowing width on wheat grain yield and its physiological causes, in the 2019-2020 and 2020-2021 winter wheat growing seasons, two sowing treatments were set under field test conditions at Shijiawangzi Wheat Test Station, Xiaomeng Town, Yanzhou District, Jining City, Shandong Province. Treatment 1 was 8 cm (B1); Treatment 2 is broadcast at 3 cm (B2). The effects of different sowing plots on photosynthetic characteristics, canopy light interception characteristics, dry matter accumulation and transport, and grain yield of wheat were studied. The results showed that the leaf area index and photosynthetically active radiation interception rate of B1 treatment were significantly higher than those of B2 treatment, and the photosynthetically active radiation transmittance of B1 treatment was significantly lower than that of B2 treatment. The relative chlorophyll content, net photosynthetic rate, transpiration rate and stomatal conductance of flag leaves under B1 treatment were significantly higher than B2 treatment, and the intercellular carbon dioxide concentration was significantly lower than B2 treatment. Dry matter accumulation at anthesis and maturity, dry matter distribution in seeds after anthesis and dry matter accumulation at maturity were significantly higher under B1 treatment than B2 treatment. The number of grains per spike and 1000-grain weight of B1 treatment were significantly higher than those of B2 treatment. Compared with B2 treatment, the two-year average grain yield and light energy utilization rate of B1 treatment increased by 6.12% and 7.71%, respectively. In summary, B1 treatment with a sowing width of 8 cm can shape a reasonable canopy structure, improve the photosynthetic performance of leaves after anthesis, and facilitate the production of photosynthetic substances of plants after anthesis, thus obtaining the highest grain yield and light energy utilization rate, which is the optimal treatment under the conditions of this experiment. This research provides a theoretical basis for wide-sowing technology of wheat with water-saving, high-yield and high-efficiency.

Key words: wheat, photosynthetic characteristics, dry matter accumulation and transport, grain yield
