木薯酒精渣-复合肥配施对木薯产量的影响初探

在等氮条件下,设计M_0F_(100)(100%复合肥)、M_(25)F_(75)(25%木薯酒精渣+75%复合肥)、M_(50)F_(50)(50%木薯酒精渣+50%复合肥)、M_(75)F_(25)(75%木薯酒精渣+25%复合肥)和M_(100)F_0(100%木薯酒精渣)等5个处理,研究了木薯酒精渣-复合肥不同配施比例对木薯产量及其构成的影响。结果表明:在等氮条件下,随着木薯酒精渣施用比例的提高,木薯产量、株高和茎径均呈下降趋势;M_(25)F_(75)和M_(50)F_(50)处理的木薯产量较M_0F_(100)处理略有下降,而M_(75)F_(25)和M_(100)F_0处理的产量显著下降;M_(25)F_(75)处理的单株薯数最多,而M_(100)F_0处理的最少;M_0F_(100)处理的单株薯重最高,而M_(75)F_(25)和M_(100)F_0处理的单株薯重较低。因此,本试验木薯酒精渣的配施比例以25%、50%为宜。
