Abstract

fetched live from OpenAlex

Introduced forage species may be necessary to improve forage production and stabilize the soils of desert steppe.From 2000 to 2004,23 perennial gramineous forage varieties and materials from the United States,Canada,and China were evaluated by plot experiments with random design on their adaptation,productivity,and forage quality in Stipa klemenzii Roshev.desert steppe in Suniteyou Banner,Xilinguole League,Inner Mongolia Autonomous Region,P.R.China.10 m2 plot was employed with 5 replicates for each variety.The results show that the overwinter survival rates of Agropyron mongolicum Keng cv.'Neimeng',A.desertorum(Fisch.) Schult.,A.mongolicum Keng (a native species),A.mongomicum Keng.(a new strain),Psathyrostachys juncea(Fisch.) Nevski cv.'swift',P.juncea(Fisch.) Nevski(P3),and P.juncea(Fisch.) Nevski cv.'Bozoisky' were above 80%.Those grasses had higher forage yields and higher crude protein contents than others and produced more root biomass that were distributed to a greater depth and spread over a wider horizontal distribution.The adaptability,high productivity,and high quality of those grasses would make them suitable for more extensive use in the desert steppe area.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

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.
