摘要
本试验在2行玉米3行大豆间作栽培模式下,播种不同的大豆品种和密度,采集叶绿素含量、光合速率、株高等数据,利用DTOPSIS法进行分析。结果表明,在2行玉米3行大豆的栽培模式下,玉米播种密度为61 500株·hm-2,大豆的适宜品种和密度分别为冀豆12(30万株·hm-2)和沧豆6号(37.5万株·hm-2)。
The research focuses on summer maize intercrops varieties and density of soybean in 2 rows of corn and 3 rows of soybean.The data of chlorophyll content, photosynthetic rate and plant height were collected and analyzed by DTOPSIS method. The results showed that soybean varieties of Cangdou No.6 and Jidou No.12 could be chosen when implementing intercropping pattern in Cangzhou area. The density of the maize was 61 500 plants·hm^-2. The density of soybean were 300 000 plants·hm^-2（Jidou No.12）and 375 000 plants·hm^-2（Cangdou No.6）.
