以“西荞二号”种子为材料,研究了不同锌质量分数和种植密度对苦荞生理特性和产量的影响.结果表明:各组合处理对苦荞苗期、现蕾期、开花结实期的生理特性和产量均有显著影响,适当的锌质量分数和种植密度组合有利于苦荞叶绿素指数、光合速率、总黄酮质量分数和产量的提高.从苦荞长势和产量角度考虑,“西荞二号”的最佳组合密度为180万株/hm2,锌浸种质量分数为0.4%.
The effects of different Zn content and planting density on the physiological characteristics and yield of tartary buckwheat were studied by using the seeds of “Xiqiao 2”. The results showed that the effects of different treatments on seedling stage, budding stage, flowering and fruiting Period physiological characteristics and yield have significant impact, the appropriate combination of zinc quality and planting density is conducive to the buckwheat chlorophyll index, photosynthetic rate, total flavonoid mass fraction and yield increased from the buckwheat growth and yield point of view, “ Xiqiao two ”the best combined density of 1.8 million / hm2, zinc soaking quality fraction of 0.4%.
