马铃薯高产栽培的最优平衡不完全区组试验设计与分析

为了研究品种及栽培方式对马铃薯产量的影响及显著程度,引入最优平衡不完全区组试验设计。结合一次马铃薯高产栽培试验,在SAS环境下,完成最优平衡不完全区组试验设计,得到试验数据,利用方差分析法对试验结果进行了数据分析。结果表明:品种和栽培方式对马铃薯产量有显著影响,品种栽培互作对马铃薯产量无显著影响,试验筛选出了适合该地区土壤和气候条件的品种及栽培方式。该研究方法可以拓展应用于马铃薯以外的其它作物高产技术领域的试验设计和分析。

The Design and Analysis of Optimal Balanced Incomplete Block Test for High Yield Cultivation Techniques of Potato

In order to define the influnce and significance of varieties and cultivation modes on potato yield, the authors introduce the optimal balanced incomplete blocks design(optimal BIBD). We realized the BIBD of a potato experiment of high yield cultivation techniques using SAS and obtained the test data, which were analyzed using variance analysis. The results showed that varieties and cultivation modes had significant effects on potato yield, the interaction between varieties and cultivation mode had no significant effect on potato yield. Suitable variety and cultivation mode under the soil and weather condition were also gained as well. This study in this paper can be adopted in high yield cultivation techniques of the other crops except potato of test design and data analysis.
