The effect of different fertilizer and transplant density treatments on main characters ofhybridize-contton, was studied in the exeperiment. The results showed that fruit shelves\boll weight\lint percentage were reduced,　while its boll numbers per plant and yield tended toincrease, along with increase of transplant density, within the range of 22500/ hm2---31500/ hm2 of density and 600kg/ hm2---1050kg/ hm2（convert into carbamide, same as following）of fertilizer treatments; Moreover yield characters of different density-treatments responsed differently, along with the increase of fertilizers level, fruit shelves per plant tended to increase, rest characters and yield were enhanced at lower density level, but tended to increase firstly, then decline slightly, while at comparatively higher density level, however they were all within the suitable range of treatment. Synthesizely, 27000/ hm2 of density and 900kg/ha of fertilizer treatment were comparatively suitable level when hybridize-contton plant at transplant-seedling area ofZhejiangprovince.
