适宜免耕覆秸精量播种栽培方式的夏大豆品种(系)筛选

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。

Varieties(Lines) Screening of Summer Soybeans Suitable for No-tillage Straw Mulching Precise Sowing Cultivation Way

In order to screen summer soybean varieties (lines) suitable for no-tillage straw mulching precise sowing cultivation way,the experiment used grey comprehensive evaluation method to analyse 12 important agronomic traits of 12 summer soybean varieties(lines) from Huang-huai-hai region,and also arranged the comprehensive evaluation ranking order of all varieties tested.The results showed that comprehensive traits of Shangdou 1201,Jidou 12 and Hedou 14 had excellent performance and high yields,so they could be used as the main planting varieties to popularize no-tillage straw mulching precise sowing technology.Agronomic traits of Zheng 7051,Zhoudou 22,Fudou 16 and Sharming 19 also had better performame and highter yields than the control,so they could be promoted appropriately.Grey comprehensive evaluation value of Wandou 21144,Xu 9302-A and Wansu 01-15 were lower than the control and yield of Zhonghuang 39 were lower than the control,but the difference were very small.In conclusion,12 summer soybean varieties(lines) were suitable for no-tillage straw mulching precise sowing cultivation method.No-tillage straw mulching precise sowing technology has a broad application prospect in huanghuai-hai region.These results would provide scientific basis for popularization and application of no-tillage straw mulching precise sowing technology and attached machines.
