滴灌下不同基追肥比例对甜玉米生长及肥料利用效率的影响
Fertilizer on the Growth and Nutrient Use Efficiency of Sweet Maize under Drip Irrigation
摘要
Abstract
This study was to deal with the effect of fertilization on growth of sweet corn,and work a reason-able ratio of base fertilizer to topdressing fertilizer under drip irrigation. A field experiment was conducted to study the effects of different ratios of base fertilizer to topdresing fertilizer on growth,yield,quality and nutrient utilization of sweet corn.The results showed that the growth,yield and nutrient use efficiency of sweet corn was influenced significantly by different ratios of base fertilizer to topdresing fertilizer.The corn yield and 100 grain weight of sweet corn in the treatment of the ratio of 1:1 were significantly higher than that in other four treat-ments,with the increments of 11.37%-39.38% and 9.68%-30.18%,repectively.The vitamin C,soluble sugar and soluble solids content of sweet corn reduced when all of the fertilizer was applied as base fertilizer.The nu-trient use efficiency in the treatment of the ratio of 1:1 had better performace than the other treatments. Com-pared with T1,the nutrient use efficiency of nitrogen,potassium and magnesium were increased by 60.84%, 65.83% and 61.92%,respectively.All these suggests that the best ratio of base fertilizer to topdresing fertilizer is 1:1,which provides a theoretical basis for sweet corn production.关键词
