简介：我们调查了高地和稻装饰用的梨树大米怎么在二个耕作方法下面对磷的(P)化肥作出回应。高地米饭Zhonghan3和稻米饭Yangfujing8两个都在潮湿的耕作下面被种(MC，控制)并且有三P的赤裸的干燥耕作(DC)铺平，低(LP，45kg/hm2)，正常(NP，90kg/hm2)并且高(HP，135kg/hm2)。当P水平增加了，高地和稻米饭的谷物收益在DC下面增加了。为任何一个米饭在在HP和NP之间的谷物收益没有重要差别，尽管高地米饭稍微增加了，稻米饭稍微在谷物产量减少了。在在LP的DC下面，Zhonghan3显示出更高级的头milled米饭率和更好的外观，煮并且吃比在HP或NP的质量。Yangfujing8类似于Zhonghan3除了之外Yangfujing8最好在NP的外观质量。在MC下面，Zhonghan3让更高级的头milled米饭在在NP的质量的LP并且更好的煮并且吃评价。除了在外观质量，Yangfujing8类似于Zhonghan3。DC改进了高地和稻米饭的头milled米饭率和外观质量，并且煮并且稻米饭的滋养的质量。与稻米饭相比，高地米饭最好处理、滋养、吃的质量。结果建议高地和稻米饭对耕作方法和磷水平不同地作出回应。
