Rice is the main food crops of chongming,this research plans through to carry on the comparison demonstration to the different variety of rice to experiment,screens the high yield and high guality new rice variety which suits Chongming local grows,then through the experiment of seeding raising materials,fertilizer application and so on tries to find out a set of practical and feasible high and stable method of cultivation. The results are summarized as follows:Using seeding raising materials can to some extent improve the hundreds of strains seeding height,dry weight index,promote seedings growth,increeding biomass accumulation,through further experimentally plant in field,indicated after the seeding raising materials the output of the rice has certain promotion.Rice cultivar Hanyouxiangqing was adopted as material in order to investigate the influences of fertilizer management at late growth stage on the growth and yield of rice. Results were as follows: Panicle fertilizer could promote the growth of rice plant, be conductive to the accumulation of dry matter and then increase rice yield significantly. Among different fertilizer management treatments, the highest rice yield was obtained when dressing panicle fertilizer without stem strong fertilizer, but when dressing stem strong without panicle fertilizer, rice yield was the lowest.After using the slow-release fertilizer,can to some extent increase rice panicles, solid grain number, 1000-grain weight, and obviously improved rice production. Slow-release fertilizer of rice under the condition of nitrogen (mu pure nitrogen 22㎏/mu), general increase 15 percent output, under the condition of reducing nitrogen 20 percent(mu pure nitrogen 18㎏/mu),output are still around 6 percent increase, even in the case of nitrogen 30 percent reduction(mu pure nitrogen 15㎏/mu), output can still remain unchanged, and have a certain degree of income.
