摘  要

 

   从各栽培红米种土样中测得pH即胜村(6.8)多依树(6.9)小新街(6.8),得到红米栽培种土壤偏酸性,从各处红米栽培种的土壤类型、全氮全磷、速效氮速效磷的分析得到:红米这种独特的水稻种有这它的独到处,适宜生长在保水保肥性差但是要透气性好的土壤里,对营养元素的依赖性小,红米种的理论产量与pH呈负相关,相关系数r为-0.0886,与全氮含量呈负相关,相关系数r为0.0734,与全磷含量呈负相关,相关系数r为-0.1536,与速效氮含量呈负相关,相关系数r为-0.0073,与速效磷呈正相关,相关系数r为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.

Keywords: Terraced Hani; Red meters; Physical and chemical properties of soil; Correlation
