为筛选出适宜麦茬免耕覆秸精量播种栽培方式的夏大豆品种(系),运用灰色综合评判法,对来自黄淮海地区的12个夏大豆品种(系)的12个主要农艺性状进行综合分析,对各参试品系的灰色综合评判等级排序。结果表明:商豆1201、冀豆12、菏豆14的综合性状表现突出、产量高,可作为推广麦茬免耕覆秸精量播种技术的主要种植品种;郑7051、周豆22号、阜豆16及山宁19的农艺性状表现也较好,产量高于对照,可适当推广种植;皖豆21144、徐9302-A及皖宿01-15灰色综合评判值低于对照,中黄39的产量低于对照,但是相差很小。本研究表明所有参试品系均适宜免耕覆秸精量播种栽培方式,免耕覆秸精量播种技术在黄淮海地区具有广阔的应用前景。
In order to screen out the summer soybean varieties (lines) suitable for sowing no-till straw fine sowing and cultivation methods, 12 major agronomic traits of 12 summer soybean cultivars (lines) from Huang-Huai-Hai area were synthesized by gray comprehensive evaluation method Analysis, the various grades of gray comprehensive evaluation of the order of the ingredients. The results showed that the comprehensive characters of Shangdou 1201, Jidou 12 and Heodou 14 were outstanding, and the yield was high, which could be used as the main planting variety to promote precision sowing technology of stubble without straw mulching. Zheng 7051, Zhou bean 22, 16 and Shanning 19 were better than those of the control, and the planting could be promoted properly. The gray comprehensive evaluation value of Wandou 21144, Xu 9302-A and Wansui 01-15 was lower than that of the control, the yield of Zhonghuang 39 Lower than the control, but a small difference. This study showed that all the tested varieties were suitable for precision sowing and cultivation of no-tillage straw, and no-tillage straw precision sowing technology had a broad application prospect in Huang-Huai-Hai region.
