不同产区及密度下豫黑芝1号芝麻产量及相关性状分析

Analysis of Yield and Related Traits of Sesame Variety Yuheizhi 1 Under Different Production Regions and Cultivation Densities

芝麻是我国重要的特色优质油料作物,提高芝麻单产水平是实现我国粮油安全生产的重要举措。为建立芝麻高产高效栽培模式,本研究以黑芝麻新品种豫黑芝1号为试验材料,在3个产区(漯河、信阳和三门峡),开展了不同栽培密度(12万、15万、18万、21万株/hm^(2))下豫黑芝1号产量及产量相关性状的变化分析。结果表明:豫黑芝1号在不同产区的生育期差异明显;种植密度对豫黑芝1号的株高、有效果节数、主茎果轴长、单株蒴果数、千粒重和单株产量等性状变化程度不同;在21万株/hm^(2)密度下,豫黑芝1号单产水平最高,达到1 463.33 kg/hm^(2)(三门峡)。

Sesame is an important characteristic high quality oil crop in our country.Increasing yield of per unit area of sesame is an important measure for realizing the safe production of grain and oil in our country.In order to establish an efficient sesame cultivation model,a new black sesame variety Yuheizhi 1 was used as experimental material in 3 production regions(Luohe,Xinyang and Sanmenxia).The yield and yield related traits of Yuheizhi 1 were analyzed under different cultivation densities(120000 plants/hm^(2),150000 plants/hm^(2),180000 plants/hm^(2),210000 plants/hm^(2)).The results showed that the growth period of Yuheizhi 1 was different in different production regions.Cultivation density had different effects on plant height,number of effective capsule nodes,fruit axis length of main stem,number of capsules per plant,1000-grain weight and yield per plant of Yuheizhi 1.Under the density of 210000 plants/hm^(2),the highest yield of Yuheizhi 1 was 1463.33 kg/hm^(2)(Sanmenxia).
