Ecological Effects of Re-Used Film Mulching during Fallow Period of Cropland
Bibliographic record
Abstract
Aiming at reducing agricultural pollution caused by plastic film, the effects of re-used plastic film mulching on soil moisture, temperatures and soil erosion during fallow period of cropland were studied, the study also investigated plastic film residue and sunflower’s yield, which compared with new plastic film mulching and bare field in Hetao region. The results showed that, compared with bare field, (1) the average soil moisture in 0~100 cm of re-used film mulching increased 2.1%, the water storage capacity in 0~100 cm and 0~20 cm increased 24.8~33.0mm and 14.9~15.5mm separately. (2) The soil average temperature significantly increased 3.1~2.8°C, especially soil temperature in 5 cm and 10 cm increased 1.7~4.6°C and 2.8~4.1°C separately (p < 0.05). (3) The amount of soil erosion significantly reduced by 68.77%. (4) Compared with new plastic film mulching, the residual plastic film of re-used film mulching cropland significantly reduced 50%, and the film use efficiency increased 1 time. (5) In addition, compared with bare field, sunflower yield of re-used film mulching was significantly increased 11.4% in 2010 and 16.8% in 2011 (p < 0.01), and compared to the new film treatment, the yield decreased 3.3% in 2010 and 2.6% in 2011 (p < 0.05). So re-used plastic film mulching can improve the ecological environment of cropland in fallow period, reduce the film pollution and increase grain yield.

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.
