濉溪县是我省大豆的主要产区之一,一般每年播种35～40万亩。由于大豆产量低而不稳,面积也不稳定,最高达60万亩,最低只有30万亩。大豆低产的主要原因为淮北地处南北气候过渡地带,大豆生育期间旱、涝灾害频繁,直接影响了大豆的生长发育;其次是品种老化,栽培管理粗放。建国40多年来,大豆亩产一直停留在几十公斤的水平上。1992年和1993年,我县承担了省大豆丰收计划项目,对大豆 Suixi County is one of the main producing areas of soybean in our province, generally sowing 35 to 40 mu per year. Due to low and unstable soybean production, the area is not stable, up to 60 million mu, the lowest is only 300,000 mu. The main reason for the low yield of soybean is that it is located in the transitional zone of north-south climate in Huaibei. The drought and flood disasters during the growth of soybean have a direct impact on the growth and development of soybean. The second is the variety aging and the extensive cultivation and management. For more than 40 years after the founding of the People’s Republic of China, soybean production has remained at a level of tens of kilograms. In 1992 and 1993, our county undertook the provincial soybean harvest project, on soybean
