The Influence of Different Seeding Rate and Nitrogen Application on Yield and Biological Characteristics of Direct Seeding Early Rice
Bibliographic record
Abstract
Hybrid early rice Liangyou 287 was used to study the relationship among the seeding rate,nitrogen application, yield and yield components of direct seeding early rice.The results showed that at the same proportion of tillering fertilizer, the maximum number of tillers increased with the increase of the proportion of nitrogen base fertilizer.At the same proportion of nitrogen base fertilizer,the maximum number of tillers decreased as nitrogen fertilizer application delayed.At the same seeding rate,spike rate increased when nitrogen fertilizer application delayed and the proportion of nitrogen base fertilizer decreased.At the same nitrogen application,spike rate decreased as the increase of seeding rate.Different nitrogen application and seeding rates had a significant impact on rice leaf SPAD value at mature stage.Liangyou 287 had the highest yield at the seeding rate of 30～45 kg/hm2 and nitrogen ratio of 50∶30∶20 for base,tillering stage and panicle stage.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
