吉林省东部高寒区不同播期及不同播深对大豆产量的影响

Effect of Sowing Date and Depth on Yield of Soybean in Eastern Cold Mountainous Area of Jilin Province

[目的]为明确吉林省东部高寒山区种植大豆的适宜播期及适宜播深提供理论参考。[方法]选用10个大豆品种,在吉林省敦化市官地镇对不同播期和不同播深开展研究,分析播期和播深对产量的影响。[结果]在吉林省东部高寒区种植大豆,4月末5月初采取3cm播深产量较高。[结论]在吉林省东部高寒山区,应选择抗寒性强品种,适宜播期为4月末5月初,控制播深3 cm。

[ Objective ] The research aimed to provide references for selecting suitable sowing date and depth for soybean with high yield in eastern cold mountainous area of Jilin Province. [ Method ] 10 soybean varieties were planted in Guandi Town of Dunhua City, Jilin Province. The effects of different sowing dates and depth on yield of soybean were studied. [ Result] High yield could be gained by sowing at the end of April or early May and 3 centimeter depth. [ Conclusion] Strong cold resistance soybean varieties should be planted and sowed at the end of April or early May and 3 centimeter depth.
