Abstract

fetched live from OpenAlex

Field experiments were conducted in Sanjiaocheng Stud Farm in two years(2001-2002),to test the effects of nitrogen fertilizer application on Elymus nutans seed yield and seed quality.Results show that the yield reached the highest rate of 1856 kg/hm~2 with 120 kg/hm~2 N application(Autumn 60+Spring 60).The fertilizer significantly raises the seed yield components,including fertile tillers/m~2,florets per spikelet,fertile florets per spikelet,and thousand-seed weight,though it does not influence spikelets per fertile tiller.The fertilizer also raises the early-mature seed germination rate,seedling length and weight,as well as the acid phosphoesterase activity.

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.
