Benefit Analysis of Soybean-corn Belt Composite Planting in Northern Guizhou
[Objective]To explore the promotion effects of soybean and corn zonal composite planting technology in northern Guizhou,and to provide scientific basis and decision-making reference for grain and oil production in northern Guizhou.[Method]Adopting the'3+2 pattern'(3 rows of soybean +2 rows of corn),the soybean and corn strip composite planting technology was popularized in 9 counties(districts)in northern Guizhou Province.[Result]Compared with 2021,the corn yield under soy-corn belt composite planting in northern Guizhou was in-creased.The maize yield was the highest in Bozhou District,followed by Fenggang County,and Tongzi County was the lowest.The soybean yield was the highest in Fenggang County,followed by Suiyang County,but Zhengan County and Daozhen Autonomous County were lower.The net income was the highest in Bozhou District,followed by Fenggang County,and Tongzi County was lowest.[Conclusion]The zonal soybean and corn composite planting technology could effectively improve the grain and oil production level in the northern Guizhou region,and played a positive role in changing the traditional planting concept,and in promoting farmers'income and ecological and social benefits.
