引言 垦区现有耕地3,183万亩,近年大豆播种面积已达1,000万亩以上,是国家重要的商品大豆生产基地。多年来,垦区大豆单产一直处在不高、不稳的状况,34年平均亩产121.4斤,最高192斤,变异幅度27.8％以上。提高大豆单产,并稳定地获得高产的技术措施研究一直引为重视。
Introduction The reclamation area now has a total area of 31.83 million mu of cultivated land. In recent years, the sown area of soybean has reached over 10 million mu and is an important commodity soybean production base in the country. Over the years, soybean yield in reclamation areas has been in a state of high and unstable instability, with an average yield of 121.4 kg and a maximum of 192 kg in 34 years, with a variation of 27.8% or more. Research on improving the yield of soybean and obtaining high yield steadily has drawn great attention.
