Abstract
In order to screen soybean varieties with high-yield,high-quality and moderate maturity suitable for the soybean-maize strip intercropping system in Yan′an City,a comparative test was conducted on 12 soybean varieties,including Qihuang 34,Zhonghuang 30,Shandou 125,and others,which have certain shade tolerance and lodging resistance.The results showed that under the soybean-maize strip intercropping system(soybean-maize row ratio of 4∶2),Qihuang 34,Qindou 2018,Baodou No.6,and Fendou 93 exhibited taller plant height,convergent plant type,good productivity,and the yield reached 2 595.45,1 946.55,2 041.50,and 1 884.45 kg/hm2,respectively.These varieties also showed higher economic benefits,with gross output values of 39 611.06,35 314.25,34 200.99,and 35 010.92 yuan/hm2,respectively.It was suggested that their demonstration and promotion areas could be expanded.关键词
