Effect of Soil Moisture on Growth and Dry Matter Accumulation of Rice in Cold Region
Bibliographic record
Abstract
To study the effect of soil moisture on growth and dry matter accumulation of rice in cold region,controlling water treatments(CWT) for the two rice varieties(Shangyu 397 and Suijing 3) at-30 to-35 kPa and-60 to-65 kPa of soil water potential were carried out during tillering stage,panicle initiation stage,1-10 days after heading,11-20 days after heading,respectively.When soil water potential(SWP) during tillering stage was kept at-30~-35kPa,the effect on plant height was very little,the culms of the two varieties were decreased apparently,and areas of three leaves from the top in two varieties were reduced differently.While SWP during panicle initiation stage was kept at-30~-35kPa,the height of the two varieties was decreased obviously and its main reason was that the internodes length from the second node to the forth node were decreased significantly,and areas of three leaves from the top in two varieties were reduced,but the culms and panicles per hill of the two varieties were increased significantly.While SWP before heading stage was kept at-30~-35kPa,the stem dry matter weight(SDM),the sheath dry matter weight(SHDM) and the panicle dry matter weight(PDM) of the two varieties during full heading stage were lower than those of CK,and exportation percentage(EP) of dry matter in every organ of two varieties also were reduced and reduced range at-60~-65kPa was greater than that at-30~-35kPa.While SWP during the beginning of heading stage was kept at-30~-35kPa,EP of dry matter in every organ of Shangyu 397 on the numerous tests was lower than that of CK,but Suijing 3 was opposite.The response of growth and development and accumulation of dry matter of different rice varieties is different on the different developing stage under the different treatmens.The effect of soil moisture on growth and dry matter accumulation of rice during tillering stage and panicle initiation stage is more serious than that in other treatments.

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.
