Abstract: Chong-ming island---the third biggest island of China，is well known with its ecological advantages and special agricultural products,such as Hanyouxiangqing(a famous rice cultivar)、cauliflower、green asparagus and so on.HACCP theory is applied to deploy research on standardize production of environmentally harmless agricultural producls. ⅰ) development and application of fertilizer mixture used for special purpose fertilizer used in treated area are reduced respectively 33.04%,38.90%,41.18% compared with chocked area. ⅱ) development and application of phytogenous or biogenous control methods,pesticide used in treated area are reduced respcctively 54.5%,51.8%,47.10% compared with check.ⅲ) Ecologically management(cultivate in the green house covered with plastic to avoid rain)to control green asparagus root wilt,the occurrence of disease decreased 72.7%～77.1%.Disease index docreased 60.1%～62.2%. The three agricultural products are produced according to the national standard regulation of environmentally harmless products manual,the avetage yields of the three main agricultural products are increased respectively 1159.5～1344.0yuan/hm2、2130.0～2221.5yuan/hm2、57174.0～63202.5yuan/hm2 than the untreated the treated areas increased 432.32 mollion yuan than before.The products are tested by national authorized agency,the result shows that the remain amount of in environment of about 20 environmental harmful materials(Heavy metal、nitrite、pesticide and so on)are under the standard of Environmental Harmless Food and Greon Food formulated by national authority.
