Abstract： To optimize technical parameters such as sowing date and seeding rate for wide -furrow wheat sowing across diferent ecological regions，this study investigated the relationship between sowing rate，sowing date，and wheat growth，development，and yield under wide -furow sowing conditions.In the autumn of 2023， a field experiment was conducted in Zhujiayuan Village，Fengming Town，Qishan County，involving diferent sowing dates and seeding rates. The results preliminarily revealed the efects of sowing date on yield performance under wide-furrow sowing and confirmed that an appropriate combination of sowing date and seeding rate was important for achieving high yield and eficiency.This study provides technical support for the large-scale adoption of wide -furrow sowing technology for wheat in the western part of the Guanzhong region.
