摘　　要：进行了直播密度和多效唑两因子对油菜“两优 586”产量及抗倒性影响的研究 ,结果表明 :以 1 8.0万株 /hm2 的直播密度结合喷施 80 0mg/kg多效唑处理的产量最高 ,达 2 2 73 .4kg/hm2 ,其单位面积有效角果数也最高 ,达 63 2 1 .6万 /hm2 ,且抗倒性较强 ,倒伏率仅 6.6%。The effects of planting density and spraying PP333 at different concentration on the yield and lodging resistance of rapeseed 'Liangyou 586' were studied,the results indicated that 'Liangyou 586' planted at the density of 180 000 plants/hm\+2 and sprayed by PP333 at the dosage of 800mg/kg had the highest yield (2 273.40kg/hm\+2) and the highest effective pods per unit area (63216000/hm\+2),and its lodging resistance was also stronger,the lodging rate being only 6.6%.\;
