Abstract

fetched live from OpenAlex

In order to understand the effects of rapeseed planting as green manure on the growth and yield of rice cultivar ‘Qing xiang ruan geng’, a rapeseed cultivar ‘Huyou21’ were used as green manure returning to field at flowering stage. The results showed that the rice plant height and chlorophyll content increased under the treatment of rapeseed returning as green fertilizer, and also increased under 20% fertilizer reduction after rapeseed returning to field. With the amount of rapeseed returning increased, the rice yield and the yield-component traits including grains per panicle and productive panicles number increased, while the 1000-grain weight deceased, but there was no statistical difference. In addition, when the rapeseed returning amount was 22.5 t/hm 2 , the rice yield was increased significantly, and also increased under that condition with 20% fertilizer reduction.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
