Screening of Soybean Varieties with Tolerance to Continuous Cropping in Hailun of Heilongjiang Province in China
Heilongjiang Province was the main soybean producing area in China,and its soybean industry development directly affected the revitalization of China's soybean industry.With the continuous expansion of soybean planting area,the phenomenon of large-scale and repeated planting of soybeans was common in production,which affected soybean yield and quality.In order to screen new soybean varieties suitable for planting in the Hailun area of Heilongjiang Province,which were tolerant,high-yield,stable,and high-quality,this article conducted a screening experiment on 16 soybean varieties that were tolerant to repeated cropping.The results showed that Wodou 29,Keshan 1,Dongsheng 17,Xinxing 1 and Wudou 188 had strong resistance to repeated cropping,and were the main recommended varieties suitable for soybean intercropping in the Hailun area of Heilongjiang Province.
