Abstract
The 4 factors and quadratic general rotary unitized design molybdenum trial are carried out at Changning area of Datong county to find out the effect of nitrogen,phosphorus,potassium and sulphur on Medicago sative L..The result showed that,as the increasing of nitrogen,phosphorus,potassium dosage,the yield of Medicago sative L.increases at first and then decreases.The best fertilizer combination is urea 225 kg/hm2,calcium super phosphate 675 kg/hm2,Canadian potassium 225 kg/hm2,suphur 15 kg/hm2.At lower nitrogen soil,the Medicago sative L.yield increases as the increasing of phosphorus dosage,but it increase at first and then decrease as the increasing of potassium;at higher phosphors soil,there is not any obviously change as nitrogen increasing,it increases as potassium increasing.At higher phosphors soil,the yield don't change obviously as nitrogen increasing,while the combination of nitrogen and phosphorus fixed at certain level,the yield of Medicago sative L.increases at first and then decreases as another fertilizer factor increasing;at lower phosphorus soil,the yield of Medicago sative L.increases at first and then decreases as sulphur increasing,at higher phosphorus,the phosphorus increases gradually as sulphur increasing.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
