Abstract

fetched live from OpenAlex

Adopting split-plot design,optimization for high yield rice population was carried out on 4 cultivars mainly planted in Sanjiang region in 2009-2010.Row spacing,plant spacing and seedling number per hill of these cultivars for high yielding cultivation were defined.The results indicated that 5-8 seedlings per hill,10 cm plant spacing and 24 cm row spacing could obtain high yield in this region.Compared with conventional production(4 seedlings per hill,13.3 cm plant spacing and 30 cm row spacing),the theoretical yield of Longjing 20 and Kenjing 3 cultivated in agricultural scientific research institute of Jiansanjiang was increased by 43.1% and 29.4% respectively,and the difference in them was highly significant.The theoretical yield of Kongyu 131 and Longjing 26 cultivated in the research and development centre of seven stars was higher than that of conventional production(increased 57.3%,47.9%),and the difference in them was also highly significant.Plant spacing and row spacing were negatively correlated with yield,and most of negative correlation between plant spacing and yield reached significant or highly significant level.Plant spacing was the most important limiting factor for high yield in the three factors.Therefore,agricultural machinery should be adjusted,which is full use of local natural resources to achieve the most efficient rice yield,a very cost-effective technical measures in Sanjiang region.

Not 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.
