Straw covering is a protective tillage measure in agricultural production, but there relatively little research on the allelopathic effects of corn straw weeds and foxtail millet. This experiment studied four (Chenopodium album, Setaria viridis, Echinochloa crus-galli Amaranthus retroflexus) millet fields, also measured growth indicators The study consisted Petri dish field experiments. Five treatments were used experiment: clear water as control (0 g/L, TCK) types extracts. They were, respectively, stock solution (100 T1), 10 X dilution (10 T2), 50 (2 T3), 100 (1 T4) Additionally, seven set up experiment, consisting three treatments, with amounts 3000 (Z1), 6000 (Z2) 12,000 kg/ha (Z3), treatments—one treatment no cover (CK) involving use black film to create same shading area covered area, coverage areas 50% (PZ1), 70% (PZ2), 100% (PZ3), respectively. results showed that extract reduced germination rate seeds weeds. T1 resulted promotion C. album inhibition S. E. crus-galli, A. retroflexus growth. Treatments T2, T3, T4 all induced order extracts comprehensive allelopathy index weed was follows: > viridis crus-galli. With an increase mulching amount, density total gradual downward trend, whereas plant effect fresh weight upward trend. All indices best under returning field. Overall, significantly impacted net photosynthetic transpiration increased yield Under coverages kg/ha, better. Based our findings, we recommend for fields.

Mechanized harvesting is a crucial step in the agricultural production of foxtail millet (Setaria italica), as its peduncles are susceptible to bending and breaking during process, leading yield losses deterioration grain quality. To evaluate suitability for mechanical harvesting, this study comprehensively analyzed biomechanical properties related biological morphological characteristics 116 accessions, establishing system indicator screening comprehensive evaluation. Using partial correlation analysis R-type cluster analysis, four seven indices peduncle were screened from 22 candidate indicators, with their coefficient variation ranging 6% 80%. The entropy method was used assign weights selected indices, factors contributing 47.4%, morphology 20.2%, spike 27.6%, plant height 4.8%. Technique Order Preference by Similarity Ideal Solution (TOPSIS) Rank-Sum Ratio (RSR) methods applied rank grade classification varieties into performance groups: Excellent (8 varieties), Good (50 Moderate (51 Poor (7 varieties). This provides scientific basis selection evaluation varieties.
