摘要
为探究叶面肥与不同钙肥配施对马铃薯空心、产量、品质调控作用和影响,为马铃薯生产中钙肥合理施用提供理论和实践参考。以中晚熟品种“黔芋7号”为试验材料,设置CK1(复合肥)、T1(复合肥+普钙)、T2(复合肥±喷钙)、T3(复合肥+普钙+喷钙)、CK2(复合肥+叶面肥)、T4(复合肥+叶面肥+普钙)、T5(复合肥+喷钙+叶面肥)、T6(复合肥+普钙+喷钙+叶面肥)共8个处理。结果表明,T1促进产量形成表现最佳,其次是T4和T5,T5块茎品质改善最为明显,抑制空心发生率效果突出的有T2、T3和T5。若以产量为主要目标,建议参照T1施肥方案。若以降低马铃薯空心缺陷为主要目标,建议参照T2施肥方案,结合经济产出效益和块茎品质,建议参照T5施肥方案。
To investigate the regulatory effects and impacts of foliar fertilizers in combination with different calcium fertilizers on potato hollo⁃wing,yield,and quality,providing theoretical and practical references for the rational application of calcium fertilizers in potato production,this experiment utilized the mid⁃to⁃late maturing variety"Qianyu No.7"as the experimental material.Eight treatment groups were established,inclu⁃ding CK1(compound fertilizer),T1(compound fertilizer+gypsum),T2(compound fertilizer±calcium spray),T3(compound fertilizer+gypsum+calcium spray),CK2(compound fertilizer+foliar fertilizer),T4(compound fertilizer+foliar fertilizer+gypsum),T5(compound fertilizer+calcium spray+foliar fertilizer),and T6(compound fertilizer+gypsum+calcium spray+foliar fertilizer).Among these treat⁃ments,T1 demonstrated the best performance in promoting yield formation,followed by T4 and T5.T5 showed the most significant improvement in tuber quality,while T2,T3,and T5 were particularly effective in inhibiting the occurrence of hollowing.If the primary objective is to maximize yield,it is recommended to follow the fertilization scheme of T1.To primarily reduce the incidence of potato hollowing defects,the fertilization scheme of T2 is suggested.Considering both economic output benefits and tuber quality,the fertilization scheme of T5 is advised for reference.
