摘要
以甜玉米华宝甜8号为材料,采用随机区组试验设计,施用相同浓度复合肥及不同浓度硫酸钾钙镁肥为底肥,研究不同浓度硫酸钾钙镁肥对甜玉米产量等性状的影响。结果表明:测产后不同施肥水平与对照相比具有极显著性差异,说明在一定浓度范围内施用硫酸钾钙镁肥对提高甜玉米产量有显著作用,具体表现为提高单穗产量,进而提高整体亩产量。每667m^2施用15、 25、 35 kg硫酸钾钙镁肥可比对照增产23.9%、 22.7%、 11.5%;增产效果明显。
The effect of different concentrations of potassium sulphate calcium magnesium fertilizer on the yield of sweet corn Huabaotan 8 were analyzed byrandomized block design of experiment.The results showed that there was significant difference between different fertilization levels and the control,the application of potassium sulphate calcium magnesium fertilizer in a certain concentration range could significantly improve the yield of sweet corn.It could increase the yield per panicle and the overall yield per mu.Applying 15,25,35 kg potassium calcium sulfate magnesium fertilizer per 667 m2 could increase the yield by 23.9%,22.7%and 11.5%compared with the control.The yield increased significantly.
