Shuitu Baochi Xuebao, 2017 在黄淮海地区冬小麦中高产田采用小区试验，以普通尿素基施、普通尿素基施加追施作对比，研究脲醛氮占总氮30%，40%，50%，60%，70%的不同脲醛缓释掺混肥在田间的氮素养分释放特征，以及对土壤氮素养分、小麦产量、氮素利用率及经济效益的影响，探明合理施用脲醛缓释肥最优氮素配比，以达到增加产量、节约资源、增加经济效益的目的。结果表明：脲醛掺混肥氮素释放量在小麦生育进程中呈现高低再高低的变化过程，脲醛氮占总氮40%或50%最有利于土壤氮素供应，脲醛氮所占比例过大或过小，都不利于小麦整个生长期氮素供应 ...

Shuitu Baochi Xuebao, 2001 1997～1999年在宁南半干旱偏旱区国家宁南(海原)旱农试区设置了旱地糜子与春小麦降水生产潜力及其适度开发试验,采用肥力梯度法研究有限降水条件下旱地糜子与春小麦的最大产量与适宜开发度.研究结果表明,宁南半干旱偏旱区旱地糜子3年(3种降水年型)平均降水生产潜力为1 760.5 kg/hm2,水分利用效率WUE为0.647 kg/m3,潜力适宜开发度为90 %,适宜施肥量为氮90 kg/hm2、磷45 kg/hm2;宁南旱地春小麦3年(1998～1999年,有冬灌)平均水分生产潜力和WUE分别为2 554.

Shuitu Baochi Xuebao, 2011 以高产冬小麦品种济麦22为材料,设置条旋耕、深松+条旋耕、旋耕、深松+旋耕和翻耕5种耕作方式处理,研究耕作方式对小麦各生育阶段土壤水分消耗和硝态氮淋溶的影响。结果表明:(1)深松+条旋耕处理小麦各生育时期棵间蒸发量、播种至拔节阶段0-40cm土层土壤贮水消耗量和农田日耗水量显著低于旋耕、深松+旋耕和翻耕处理的;开花至成熟阶段60-120cm土层土壤贮水消耗量、农田日耗水量和灌浆后期旗叶水势显著高于其他处理的。(2)深松+条旋耕处理成熟期0-80cm土层土壤硝态氮含量与深松+旋耕处理的无显著差异 ...
