摘要:

为了研究不同基因型玉米间混作的效应,以6个不同基因型玉米品种为试验材料,组成3对组合、9个处理,利用基于熵值赋权的DTOPSIS法对其单作和间作效应进行了综合分析和比较,探索比较分析的新方法,得到不同基因型玉米间作的优势配型新模式。结果表明:处理4的Ci值最大,C4=0.9829,处理5的Ci值最小,C5=0.0330,其余2对组合的间作Ci值均大于单作Ci值,‘DH605’与‘WK702’、‘DH618’与‘DH371’间作配型模式,具有增产增效的作用,可在生产推广中应用。

Abstract:

In order to study the effect of intercropping of different maize genotypes, six maize varieties of different genotypes were used as experimental materials to set 3 combinations and 9 treatments. The monoculture and intercropping effect were analyzed comprehensively and compared by using DTOPSIS method (dynamic technique for order preference by similarity to ideal solution) based on entropy weight. Through exploring new methods of comparative analysis, a new dominant pattern of maize intercropping with different genotypes was obtained. The results showed that the Ci value of treatment 4 was the highest (C4=0.9829), and that of treatment 5 was the lowest (C5=0.0330). The Ci value of the other two combinations of intercropping were all greater than the Ci value of monoculture. The intercropping pattern of ‘DH605’ with ‘WK702’, and ‘DH618’ with ‘DH371’ had the effect of increasing yield and efficiency, which could be applied in production.
