摘要: [目的]研究尿素中添加硝化抑制剂碧晶N+随水滴灌对灰枣生长以及品质的影响.[方法]以红枣为试材,设置添加浓度为纯氮量的0.3;的硝化抑制剂碧晶N+与不添加的处理,测定果园土壤中的NH4+-N含量与NO3--N含量,枣果产量与品质.[结果]土壤中的NH4+-N含量提高22.3; ~ 32.8;,NO3--N含量降低12;~35.7;;枣吊坐果数、单株坐果数与单株产量分别提高了105; 、95;与94;,可溶性固形物、糖和VC含量略有提高.[结论]添加硝化抑制剂碧晶可显著抑制土壤中的硝化作用,增加土壤中的铵态氮比例,延长氮肥肥效,增加红枣枣吊坐果数和单株坐果数,增加枣产量;提高果品中可溶性固形物、糖和VC含量及整齐度,增加枣果的商品性.
