Comparative Study on Agronomic Traits and Yield of Six Oat Varieties under Different Climatic Conditions
摘要
Abstract
[Objective]This study aimed to explore the effects of climatic conditions on the agronomic traits,lodging rate and yield of oat varieties,and to provide a scientific basis for the rational selection and promotion of oat varieties in different climatic regions.[Methods]Six oat varieties were selected as the research objects,and a comparative experiment was performed in two areas differing in climatic characteristics.During the experiment,local conventional water and fertilizer management practices were adopted,and the duration of the growth period was recorded.At the milk-ripe stage,agronomic and yield indicators such as plant height,lodging rate,stem-leaf ratio and dry hay yield were measured to analyze the effects of climatic conditions on the growth and yield of oats.[Results]The growth period days of the six oat varieties in Hutubi experimental site were all shorter than those in Aheqi experimental site,especially for Bayan No.3,whose growth period was shortened by 32 days.The lodging rates of the six oat varieties in Aheqi experimental site were all lower than those in Hutubi experimental site,with extremely significant differences(P<0.01)for Bayan No.3 and Qinghai Sweet Oat,and significant differences(P<0.05)for Qinghai 444,Baiyan No.7 and Guyan No.4.The stem-leaf ratios of only two varieties,Bayan No.3 and Qinghai 444,showed significant differences(P<0.05)between the two experimental sites,and the ratio in Aheqi experimental site was higher than that in Hutubi experimental site.Plant height was positively correlated with yield.The dry hay yield of Qinghai Sweet Oat in Aheqi experimental site reached 459 975 kg/km2.In Hutubi experimental site,Qingyin No.2 presented the highest yield of 1 106 940 kg/km2,followed by Qinghai 444 at 1 070 835 kg/km2.[Conclusion]Climatic conditions had significant effects on the growth period,lodging rate,stem-leaf ratio and dry hay yield of oat varieties,and there were obvious differences in the adaptability of different oat varieties to climatic conditions.Aheqi experimental site was more suitable for planting Qinghai Sweet Oat,while Hutubi experimental site was more suitable for planting the Qingyin No.2,followed by the promotion of Qinghai 444.Theoretical support was provided by this study for the rational layout and high-yield cultivation of oat varieties in the two regions.关键词
