摘 要:试验利用灰色系统理论对影响大豆产量的农艺性状进行分析,确定在垄三和小垄密植不同栽培模式条件下影响大豆产量的主要因素,为大豆育种和栽培提供科学依据。对大豆主要性状关联度的计算及关联序的排列。结果表明,在窄行密植栽培模式下,产量与主要性状的关联度大小依次为株高>单株粒重>主茎节数>有效荚数>百粒重>地上部干物重>单株粒数>底荚高;在垄三栽培模式下,关联度顺序为单株粒重>百粒重>有效荚数>株高>底荚高>主茎节数>单株粒数>地上部干物重。Agronomic traits which affected the yield of soybean were analyzed by using the gray system theory in the experiment, the main factors affecting production was determined in narrow row and three lines of ridge, to provide a scientific basis for breeding and cultivation of soybean. A grey correlation cardinality method was employed to calculate the degree of association of soybean main traits in narrow row and three lines of ridge. The results showed that the correlation order between agronomic traits and yield was as follows: plant height〉seed weight per plant〉main stem node number〉effective pod number〉100-seed weight〉dry matter accumulation above-ground part〉seed number per plant〉height of lowest pod in narrow row and dense growth, which were as follows: seed weight per plant〉100-seed weight〉effective pod number〉plant height〉height of lowest pod〉main stem node number〉seed number per plant〉dry matter accumulation in above-ground parts in three lines of ridge cultivation.
