| Abstract: | 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. |
| Keywords: | Rapeseed with double lOW content "Heza 7" Fertilizer rate Method of fertilizer application Planting density Yield |
