摘要
通过温室条件下的随机区组实验,探讨了不同磷肥配施方式对作物磷肥有效利用率的影响。实验设置对照组和2种不同磷肥配施方式处理组(磷肥组A和磷肥组B),分别采用基肥和追肥结合的施肥方式以及一次性基肥施用方式。在25℃、60%湿度的温室环境中,每周记录作物的高度、叶片数和生物量,并在收获时测量最终产量。结果显示,磷肥组A在各项指标中均表现最佳,平均高度从6.0 cm增加到24.2 cm,最终产量为3258 kg·ha^(-1),显著高于对照组的2983 kg·ha^(-1)和磷肥组B的3027 kg·ha^(-1)。此外,磷肥组A的作物体内磷质量分数在收获时达到0.47%,显著高于磷肥组B的0.41%和对照组的0.26%。实验结果表明,基肥和追肥结合的施肥方式能够显著提高磷肥的利用效率,促进作物生长和产量。
Through random block experiments under greenhouse conditions,the impact of different phosphate fertilizer application methods on the effective utilization rate of crop phosphate fertilizer was explored.The experiment set up a control group and two treatment groups with two different phosphate fertilizer application methods(phosphate fertilizer group A and phosphate fertilizer group B),respectively using a combination of base fertilizer and top dressing and a one-time base fertilizer application method.In a greenhouse environment at 25℃and 60%humidity,crop height,leaf number,and biomass were recorded weekly,and final yield was measured at harvest.The results showed that phosphate fertilizer group A performed best in all indicators,with the average height increasing from 6.0 cm to 24.2 cm,and the final yield was 3258 kg∙ha^(-1),which was significantly higher than the control group's 2983 kg∙ha^(-1) and 3027 kg∙ha^(-1) of phosphate fertilizer group B.In addition,the phosphorus mass fraction in the crops of phosphate fertilizer group A reached 0.47%at harvest,which was significantly higher than the 0.41%of phosphate fertilizer group B and the 0.26%of the control group.Experimental results showed that the combination of base fertilizer and top dressing could significantly improve the utilization efficiency of phosphate fertilizer and promote crop growth and yield.
