嘉兴市高标准农田地力建设成效的评估与分析

Evaluation and analysis on effectiveness of high standard basic farmland fertility construction in Jiaxing city

按照《浙江省标准农田地力调查与分等定级技术规范》开展标准农田地力分等定级,在摸清标准农田地力质量现状的基础上,开展了标准农田质量提升工程。嘉兴市秀洲、嘉善、平湖县(市、区)2009年项目(面积4015.6 hm2)实施了秸秆还田、增施商品有机肥、测土配方施肥、翻耕加深耕作层、调整土壤酸度、改善农田排灌等技术措施。2年后对该项目进行地力培育的成效评估,结果显示,由二等田(地力综合指数0.60～0.80)提高到一等田(地力综合指数0.80以上)的面积占65.89%,未达到一等田的地力综合指数也提高0.04～0.10。文章分析了标准农田质量提升工程的技术问题,并提出嘉兴市高标准农田的地力建设目标应为一等田。

A According to the standard of Technical Specifications and Classification of Standard Farmland Fertility Sur- vey in Zhejiang province ,＂ evaluation and classification of the standard farmland quality as well as the promotion pro- ject 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. Ef- fectiveness 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 in- creased 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.
