淮北地区是我省大豆主要产区,多年来大豆亩产一直在50—80千克徘徊。为了提高大豆产量,有关单位曾做过许多单因子或复因子试验,但因试验方法功能局限,实际上很难全面描述所研究因子与产量的关系。我们于1986年运用二次回归正交旋转组合设计方法,进行了淮北地区大豆高产栽培综合农艺措施选优研究。试验结果表明:在淮北地区当前生产条件下,采取适宜综合农艺措施,大豆可以取得较理想的产量。通过微机的模拟试验,可筛选出大豆高产栽培各项技术因素组合的较佳范围。
Huaibei area is the main producing area of soybean in our province, over the years the soybean yield has been hovering 50-80 kg. In order to increase the yield of soybean, many single factor or complex factor tests have been conducted by the relevant units. However, due to the limitations of the test methods, it is actually very difficult to describe the relationship between the factors studied and the yield. We used quadratic regression orthogonal rotation combination design method in 1986, carried out in Huaibei soybean high yield cultivation comprehensive agronomic measures optimization research. The results showed that under the current conditions of production in Huaibei area, adopting appropriate agronomic measures, soybean could achieve better yield. Through the computer simulation test, we can screen out the better range of the combination of various technical factors of soybean high yield cultivation.
