| 摘 要： | 根据野外调查采样与室内分析,引入灰色系统理论的共联分析法,对白银市中心区大田土壤养料肥力因素对春小麦产量的影响进行分析比较研究。结果表明:在干旱地区土壤 pH 值对春小麦产量最为显著;其次是有机质和速效磷;与 CaCO_3和粘粒含量的关系较为疏远.并提出提高产量的合理化建议.

| Abstract: | Based on the results of fieldwork and indoor analysis and by using the method of grey connected analysis,the paper analyzes the effect of soil nutrient fertility factors on wheat yield in the central area of Baiyin,Gansu.The re- sult is that the elation between pH value and wheat yield is the first;organic matter and available phosphorous the second;CaCO_3 and texture the third. Finally the paper puts forward reasonable suggestions to raise wheat yield. |
