摘　　要：对双低油菜品种"核杂7号"进行不同施肥量、施肥方法和种植密度试验。结果表明:"核杂7号"氮肥适宜施用量为225～315 kg/hm^2;当氮肥施用量225 kg/hm^2时,年后氮肥施用比例应为25%～40%;种植密度为6.0万～10.5万株/hm^2。In order to improve the yield of rape cultivar＂Heza 7＂with double low content, experiments with the cultivar were carried out in terms of fertilizer rate, method of fertilizer application and planting density at .3 different locations in Shanghai suburbs. The results showed that in order to obtain a high yield of the cultivar.the appropriate nitrogen ferlilizer rate should be 225 -315 kg/hm^2 ;the suitable proportion of nitrogen fertilizer application in the next year should be 25% -40% when the nitrogen fertilizer rate was 225 kg/hm^2 ; and the planting density should be 60 000-105 000 plants/hm^2.
