What does this research mean for the field?

While Chinese solar greenhouses effectively buffer external low temperatures during autumn-winter tomato production, they experience stage-specific thermal mismatches, weak indoor light availability, and insufficient synergistic humidity regulation. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To quantitatively assess the microclimatic performance of a Chinese solar greenhouse across four growth stages of autumn–winter tomato cultivation and determine environmental alignment with crop needs.

Implication

Observational study reveals stage-specific thermal and humidity mismatches during greenhouse tomato cultivation, highlighting the need for dynamic microclimate control strategies.

Key Points

To quantitatively assess the microclimatic performance of a Chinese solar greenhouse across four growth stages of autumn–winter tomato cultivation and determine environmental alignment with crop needs.
Monitored continuous microclimate parameters, including air temperature, solar radiation, and relative humidity, across four growth stages: Seedling, Flowering, Swelling, and Fruiting.
Calculated indoor versus outdoor growing degree days (GDD), relative GDD index (RGI), solar radiation transmittance, and stage-specific relative humidity suitability rates.
Indoor growing degree days reached 1326.77 °C·d compared to 476.30 °C·d outdoors, with relative GDD index indicating thermal surplus during Seedling stage (1.64) and severe heat deficit during Fruiting (0.67).
Indoor daily mean accumulated radiation ranged from 7.05 to 8.12 MJ·m−2·d−1 with transmittance rising from 61% to 85%, constrained by outdoor seasonal light declines.
Relative humidity suitability dropped from 57% in the Seedling stage to 16%, 12%, and 17% in subsequent stages, with high humidity exceeding 80% during 67% of Swelling and 72% of Fruiting stages.
