Abstract: According to the standard of Technical Specifications and Classification of Standard Farmland Fertility Survey in Zhejiang province， evaluation and classification of the standard farmland quality as well as the promotion project of standard farmland quality were carried out based on exploring soil fertility quality of standard farmland. The project area of promoting standard farmland quality in Xiuzhou， Jiashan， and Pinghu county was 40156 hm2. The straw returning into the field， increasing rate of commercial organic fertilizer， soil testing and fertilizer formulation， deep plowing， adjusting soil acidity， improvement of farmland irrigation were applied to these farmland in 2009. Effectiveness of farmland fertility improvement was evaluated after 2 years. The results of the assessment showed that the area proportion of first-class standard farmland （integrated fertility index above 0.80） was increased from 0 in 2009 to 65.9% in 2011. The integrated fertility index of the farmland below first-class standard farmland was increased by 0.04-0.10. The paper discussed the technical problems of the promotion project of standard farmland quality. The construction goal of the high standard farmland in Jiaxing city should be the first-class field.

Key words: standard farmland, fertility construction, fertility evaluation, Jiaxing city
