摘 要
從各栽培紅米種土樣中測得pH即勝村（6.8）多依樹（6.9）小新街（6.8），得到紅米栽培種土壤偏酸性，從各處紅米栽培種的土壤類型、全氮全磷、速效氮速效磷的分析得到：紅米這種獨特的水稻種有這它的獨到處，適宜生長在保水保肥性差但是要透氣性好的土壤里，對營養(yǎng)元素的依賴性小，紅米種的理論產(chǎn)量與pH呈負(fù)相關(guān)，相關(guān)系數(shù)r為-0.0886，與全氮含量呈負(fù)相關(guān)，相關(guān)系數(shù)r為0.0734，與全磷含量呈負(fù)相關(guān)，相關(guān)系數(shù)r為-0.1536，與速效氮含量呈負(fù)相關(guān)，相關(guān)系數(shù)r為-0.0073，與速效磷呈正相關(guān)，相關(guān)系數(shù)r為0.3974。

ABSTRACT
From the cultivation of red rice soil pH namely wins measured 6.8) in accordance with the village (more than tree (6.9) small new street (6.8), get red rice culture kind of soil from everywhere red, partial acidic soil cultivated rice types, total nitrogen total phosphorus, available nitrogen organic p analysis get: red rice this unique ShuiDaoZhong have this its original, suitable for growth in the retention of poor but to permeability good water-stable aggregate to soil nutrition elements of a small, red meters dependence theory of negatively correlated yield and pH, correlation coefficient r for -0.0886, and negatively correlated to total nitrogen content, correlation coefficient r for -0.0734, and negatively correlated to the total phosphorus, correlation coefficient r for -0.1536, and available nitrogen content, correlation coefficient negatively correlated with - 0.0073, rove as rapidly-available phosphorus, correlation coefficient r positively correlated to 0.3974.
