摘要
在等氮条件下,设计M0F100(100%复合肥)、M25F75(25%木薯酒精渣+75%复合肥)、M50F50(50%木薯酒精渣+50%复合肥)、M75F25(75%木薯酒精渣+25%复合肥)和M100F0(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;M25F75和M50F50处理的木薯产量较M0F100处理略有下降,而M75F25和M100F0处理的产量显著下降;M25F75处理的单株薯数最多,而M100F0处理的最少;M0F100处理的单株薯重最高,而M75F25和M100F0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。
Five treatments of M0F100(100%compound fertilizer),M25F75(25%cassava ethanol residue+75%compound fertilizer),M50F50(50%cassava ethanol residue+50%compound fertilizer),M75 F25(75%cassava ethanol residue+25%compound fertilizer)and M100 F0(100%cassava ethanol residue)were designed in the condition of equal nitrogen.The effects of different combinations of cassava ethanol residue and compound fertilizer on cassava yield were studied in the experiment.The results showed that the yield,plant height and stem diameter of cassava decreased with the increase of the proportion of cassava alcohol residue in the same nitrogen condition.The yields of M25F75 and M50F50 treatments were slightly lower than that of M0F100 treatment,while those of M75F25 and M100F0 treatments decreased significantly.M25 F75 treatment had the largest number of potatoes per plant,while M100F0 treatment had the least.The single plant weight of M0F100 treatment was the highest,while the single plant weight of M75F25 and M100F0 treatment was lower.Therefore,25%and 50%cassava alcohol residue should be applied in this experiment.
