Community Structure of Soil Nematodes in Soybean Fields under Different Rotation Systems
Bibliographic record
Abstract
Soil nematodes are numerous,species-rich and widely distribute,which play essential roles in soil organic matter decomposition,plant nutrient mineralization and nutrient circulation.More and more scholars pay attention to the important function of soil nematodes in agroecosystem.The study was conducted in the soybean field under continuous cropping (CS,15a),wheat-soybean-wheat-soybean (WSWS,15a) and wheat-maize-soybean (WMS,15a) rotation systems in Hailun Agricultural Ecology Experimental Station so as to elucidate the character of nematode distribution and dynamic change of nematode community.Totally 8 order,19 family and 43 genera nematodes were identified in soybean field and 29 genera nematodes were shared by each treatments,other 14 genera were different among samples in that their distribution were affected by the crops stubbles and soil environment.Total number of soil nematodes was exhibited low to high to low trend in CS and continous higher in WSWS and WMS at the sample stages.The number of Ditylenchus,Acrobeloides,Mesorhabditis,Protorhabditis,Panagrolaimus,Filenchus and Coslenchus was different among soybean rotation systems.

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.
