摘　　要：采用二因素裂区设计,于2005～2006年进行了不同播种期和密度对油研11号主要性状的影响试验,结果表明:不同播期和密度均会影响油研11号的产量、生育期、植株性状等;点播油研11号的最佳播期为9月下旬,密度为10000株/667m2,若因轮作茬口的不同,可以调节种植密度,以获得更高产量;在10月中、下旬播种时,则以15000株/667m2的密度最为适宜。The two-factor split plot design was used to investigate effects of different sowing time and density on main characters of Yuoyan 11. The results show that the different sowing time and density affect yield, growth period and plant character of Youyan 11. The optimum sowing time and density under the hill seeding are on the last ten-day period of September and 10000 plants/667m^2. The planting density should be adjusted according to the crops of rotation and the density of 15000 plants/667m^2 should be used when sowing time is on the middle and last ten-day period of October.
