三个马铃薯早熟品种在黑龙江省不同地区的产量表现

Yield Performance of Three Early-Maturing Potato Varieties in Different Regions of Heilongjiang Province

为研究马铃薯产量形成的影响因素及规律,选用马铃薯早熟品种尤金、费乌瑞它和早大白,分别种植在黑龙江省不同纬度的地区,自然成熟后测定产量,计算大中薯率。结果表明,产量和大中薯率均极显著受品种和地点的影响,且地点的影响大于品种,所有处理的产量受品种和地点互作效应影响显著,大中薯率受影响达极显著水平。3个品种的小区产量均表现为加格达奇地区最低,尤金和费乌瑞它在牡丹江地区的产量最高,早大白在哈尔滨的产量略高于牡丹江但差异不显著;大中薯率的表现为尤金和费乌瑞它在加格达奇最低,早大白在绥棱最低,略低于加格达奇,但差异不显著,尤金和费乌瑞它大中薯率最高值出现在哈尔滨,其次是牡丹江,早大白则相反,但差异均不显著。

In order to study the influencing factors and laws of potato yield formation,the early-maturing potato varieties Youjin,Favorita and Zaodabai were selected and planted in different latitudes of Heilongjiang Province.After natural ripening,the yield and the rate of large and medium sized potato were calculated.The comparison results showed that the yield and the rate of large and medium-sized potato were significantly affected by varieties and locations,and the location had more influence on it than the variety.The yield of all treatments was significantly affected by the interaction effect of varieties and locations,and the rate of large and me dium-sized potato was extremely significantly affected.The yield of three varieties was the lowest in Jiagedaqi District.Youjin and Favorita had the highest yield in Mudanjiang.Zaodabai had a slightly higher yield in Harbin than Mudanjiang,but the difference was not significant.Youjin and Favorita had the lowest rate of large and medium-sized potatoes in Jiagedaqi.Zaodabai had the lowest rate in Suiling,slightly lower than Jiagedaqi,but the difference was not significant.The highest rate of large and medium-sized potatoes of Youjin and Favorita appeared in Harbin,followed by Mudanjiang.Zaodabai was contrary to them,but the difference was not significant.
