The writers choose 26 typical soil species, 13 variables (assessment items), and digitize the physical and chemical properties of the soil species.
在含山县水稻土资源质量评价中 ,选用 2 6个典型土种 ,13个变量 (评价项目 ) ,先对土种理化性质进行数字化处理 ,采用逐步回归分析法筛选出影响水稻生产力的主导因子并建立回归方程 ,对入选因子的回归系数进行标准化处理后求得其权重以及土种各因子的具体评价指数 ,最后进一步对所有土种进行综合评价并进行归类分等 ,评价的结果与实际完全一致 ;通过对含山县水稻土资源质量评价的尝试初步探讨了其科学方法及存在问题 ,同时也为含山县水稻土资源的合理利用提供科学依
2) soil local type
土种
1.
Relations between soil nitrogen and other nutrients and rice basal yields in different soil local types;

2.
By the experiments that the soil nutrients were determined and the plots were not applied with nitrogen as controls in this study, the status of soil nutrients in Jiangyan county, which lies in the middle area of Jiangsu Province, was primarily definituded and the relations between rice basal yields and soil nutrients in different soil local types were analyzed.
本文以地处苏中的姜堰市为例,通过土壤养分测定与不施氮空白区试验,初步明确了该市土壤养分状况,分析了不同土种土壤氮等养分与水稻基础产量的关系,建立了不同土种不施氮空白区水稻基础产量模型,并进一步明晰了适于当地应用的水稻精确施氮三参数,即:目标产量100 kg籽粒吸氮量、土壤当季供氮量(基础产量及100 kg籽粒吸氮量)、氮肥当季利用率,进而开发出了基于组件式GIS的县域水稻精确施氮决策支持系统V1。
