为筛选适配陇东旱塬区生态条件的庆阳红酒谷高产高效栽培模式，设置覆土穴播、平铺穴播、双垄沟播、微垄穴播、露地穴播5种种植模式，系统评估其对庆阳红酒谷产量、营养品质及经济效益的影响。结果表明，覆土穴播综合表现最优，庆阳红酒谷产量达3 696.0 kg/hm2，较对照露地穴播增产64.82%，净收益11 976.4元，增幅79.98%，粗蛋白(126.6 g/kg)、粗淀粉(794.4 g/kg)、直链淀粉(303.0 g/kg)、赖氨酸(1.9 g/kg)含量均最高；平铺穴播、微垄穴播次之，产量分别为3 196.5、3 184.5 kg/hm2，净收入9 528.9、9 470.1元/hm2；双垄沟播产量3 063.0 kg/hm2，净收入8 874.7元/hm2；对照露地穴播粗脂肪含量(39.2 g/kg)较高，但综合产量、经济效益最低。所有覆膜处理均具有集雨保墒增温效应，其中覆土穴播能有效协调并显著提升庆阳红酒谷的产量、营养品质与经济效益，为最优种植模式，适宜在庆城县及相似生态区扩大示范推广。

To screen a high-yield and efficient cultivation mode of Qingyang red wine millet suitable for the ecological conditions in the dry plateau area of Longdong, this study conducted a comparative experiment with 5 planting modes, soil-covered hole seeding (SCHS), flat hole seeding (FHS), double-ridge furrow seeding (DRFS), micro-ridge hole seeding (MRHS), and open-field hole seeding(CK), to systematically evaluate their effects on crop yield, economic benefits, and nutritional quality. Results showed that SCHS exhibited the optimal comprehensive performance: its yield reached 3 696.0 kg/ha, representing a 64.82% increase compared with CK, the net profit was 11 976.4 Yuan/ha with an 79.98% increase relative to CK. Meanwhile, SCHS achieved the highest contents of crude protein (126.6 g/kg), crude starch (794.4 g/kg), amylose (303.0 g/kg), and lysine (1.9 g/kg). FHS and MRHS ranked second, with yields of 3 196.5 and 3 184.5 kg/ha, respectively, and net incomes of 9 528.9 and 9 470.1 Yuan/ha, respectively. The yield in DRFS was 3 063.0 kg/ha with the net income of 8 874.7 Yuan/ha. Although CK had a relatively high ether extract content(39.2 g/kg), it showed the lowest comprehensive yield and benefits. All mulching treatments exhibited significant effects of rainwater harvesting, soil moisture retention, and temperature increase. As the optimal mode, SCHS can effectively coordinate and significantly improve the yield, nutritional quality, and planting economic benefits of Qingyang red wine millet, making it suitable for expanded demonstration and promotion in Qingcheng County and similar ecological regions.
