Shuitu Baochi Xuebao, 2018 为改善江汉平原地区稻田水肥管理措施，采用田间小区试验，研究了常规淹灌（CF）和浅灌深蓄（SIDS）条件下，农民习惯施肥（FFP）、30%尿素+70%控释参混肥（30%N+70%CRF）和优化减氮施肥（OPT-N）对水稻各生育阶段稻田氮磷流失特征、养分吸收和土壤养分积累的影响。结果表明：与CF处理相比，SIDS处理田间灌溉水量、总用水量、径流量和渗漏量分别降低41.7%，18.5%，45.8%和21.9%，降雨利用率增加16.2%，TN和TP径流流失量分别降低32.6%～35.9%和36.4%～53.1%，

Shuitu Baochi Xuebao, 2020 在南方典型双季稻种植区，通过2年试验综合评价在有机无机肥配施基础上施用锌肥和石灰对双季稻产量与土壤养分特性的影响，以期提出培肥土壤和提高水稻产量的理想施肥模式。设置有机肥+无机肥（T1）、锌+有机肥+无机肥（T2）、石灰+有机肥+无机肥（T3）、锌+石灰+有机肥+无机肥（T4）4个处理，测定了土壤有效锌、碱解氮、有效锌含量和pH，分析了水稻产量和土壤综合肥力。结果表明：（1）相比T1处理，T2处理显著提高了早晚稻千粒重和结实率，显著增产8.7%，而T3处理不利于水稻稳产，显著降低了千粒重，并在第2年减产（
