丘陵区水稻施肥模型研究

Study on Rice Fertilization Models in Hilly Area

以重庆市江津区大量水稻施肥的田间试验结果和分析数据为依据,经过多点试验资料的归类或聚类,建立水稻在不同肥力条件下的肥料效应数学模型,提出水稻的施肥模型和氮、磷、钾最佳施肥方案.

Appropriate models according to different fertilization conditions were constructed on the basis of plentiful field experiment resultsand analyses data of rice balanced fertilization in Jiangjin, Chongqing. Fertilizer models and optimum proportion of nitrogen, phosphorus, and potassium schemes for rice in hilly area were put forward using classifying and clustering analyses.
