Abstract: In order to solve the plant density and fertilizer levels of organic rapeseed cultivation, the use of organic fertilizer use Nong-Fuwang in organic production, to explore the optimal cultivation pattern of the organic fertilizer rate of rape and density. The effect of fertilization amount and density on yield of organic rape was studied by using split plot design. Results showed that the organic rape yield which factors analysis the highest percentage of per plant effectively occurred when the high fertilizer rate and high density pod, the highest of pod grain number gained under high fertilizer level and low- density. Under the same planting density, effective pod per plant and pod grain number increased but the balance of power between the groups was not obvious. Organic rape yield was little impact on organic fertilizer levels of 3000-5250 kg/hm2, the yield difference was significant in the organic rape planting density; it was no effect of interaction between the two. Combinedallthefactors, the appropriate amount and density of organic rape were the organic fertilizer 3750kg/hm2 and planting density of 300000 per hm2.
