- Intervention effect Under S1 shading, wheat chlorophyll a content increased by 2.9–24.5% compared with normal light.
- Intervention effect Under S1 shading, wheat chlorophyll b content increased by 16.5–28.9% compared with normal light.
- Intervention effect Under S1 shading, wheat chlorophyll a + b content increased by 7.8–25.5% compared with normal light.
- Intervention effect Increasing shading range decreased total dry matter accumulation, reproductive dry matter accumulation and yield of wheat.
- Intervention effect Increasing shading range decreased net photosynthesis rate, transpiration rate and stomatal conductance of wheat.
- Intervention effect Increasing shading range decreased non-photochemical quenching coefficient of wheat.
- Intervention effect Under S0 and S1, N2 treatment increased wheat leaf area index by 4.1–366.9% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat chlorophyll content by 5.7–56.3% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat net photosynthesis rate by 3.0–131.7% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat actual photochemical efficiency by 6.7–87.5% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat photochemical quenching coefficient by 3.7–96.9% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat total dry matter accumulation by 7.1–340.8% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat dry matter accumulation of reproductive organs by 0.3–323.0% compared with other nitrogen treatments.
- Intervention effect Under S0 and S1, N2 treatment increased wheat yield by 1.5–231.2% compared with other nitrogen treatments.
- Recommendation Under moderate or excessive shading, the regulating effect of nitrogen application on wheat is reduced and nitrogen application should be moderately reduced.
- Recommendation Under light shade in the early stage, proper nitrogen application can regulate wheat photosynthetic capacity and dry matter transfer and compensate for the negative effect of insufficient light on wheat yield.
