【摘要】：【目的】研究不同密度对6个基因型马铃薯产量和大中小薯个数的影响。【方法】在大田条件下,采用4种密度(主处理)和6个不同用途基因型马铃薯(副处理)两因素裂区设计,通过方差分析、线性拟合、多重比较显著性检验和相关性分析进行研究。【结果】不同基因型对产量、大中小薯个数的影响达到极显著水平,不同密度对中薯个数的影响达极显著水平,对产量、大小薯个数的影响达显著水平(Duncan多重比较)。密度和不同基因型之间不存在互作。随着密度的增加产量、大中小薯个数增加,但薯块平均重量在降低。【结论】为了获得数量多的小整薯个数不同的品种有最适宜的密度。不同密度对不同基因型马铃薯块茎大小分布呈规律的数学模型,根据数学模型可以很好的预测马铃薯大中小薯块茎个数和总薯个数。
[Abstract]:[objective] to study the effects of different densities on yield and number of large and medium potato in 6 genotypes. [methods] under field conditions, Four different densities (main treatment) and six genotypes of potato (para-treatment) were used to design the split zone. The results were analyzed by ANOVA and fitted linearly. Multiple comparative significance test and correlation analysis were carried out. [results] the effects of different genotypes on the yield, the number of large, medium and small tubers reached a very significant level, and the effects of different densities on the number of middle and small tubers reached a very significant level. The effect of the number of large and small tubers was significant (Duncan multiple comparison). There was no interaction between density and different genotypes. With the increase of density, the number of large, medium and small tubers increased, but the average weight of tubers decreased. [conclusion] in order to obtain a large number of varieties with different numbers of small whole tubers, there is the most suitable density. According to the mathematical model of different density distribution of potato tuber, the number of tuber and the total number of tubers can be well predicted.
