黄土塬区麦田水分、氮素平衡及生产力的试验与模拟研究

, 2010
水分和养分(特别是氮素营养)一直是制约黄土高原地区作物生产力提高的主要限制性因素。探讨不同水肥条件下冬小麦水氮利用及生产力变化规律，对于本地区麦田合理施肥及作物产量提高等具有重要意义。 本研究针对黄土塬区降水少且季节分配不均，土壤严重缺氮的特点，设置了雨养及补充灌溉条件下不同氮磷配施冬小麦种植试验，并依托长期定位施肥试验，结合DSSAT模型，通过田间试验及DSSAT模型模拟相结合的方法，对黄土塬区不同水肥条件下冬小麦生产力及水分、氮素平衡过程进行了试验研究与模型模拟，主要结论如下： (1 ...

水肥一体化追氮配施氮肥增效剂对冬小麦生长和氮素利用率的影响

Shuitu Baochi Xuebao
目的为探讨添加氮肥增效剂对小麦生长、产量及氮素利用率的影响。方法试验共设对照（CK）、U（T1）、U＋NBPT（T2）、U＋DMPP（T3）和U＋NBPT＋DMPP（T4） 5个处理，在拔节期水肥一体化追肥，比较各处理对冬小麦生长、产量、氮肥利用率及生理特性的影响。结果与T1处理相比，T2~T4均能提高小麦株高、干物质量和产量，其中，T4干物质量和产量分别显著提高32.35%和17.19%；T2~T4均能显著提升小麦水氮利用效率，提高土壤供氮能力，其中，T4氮素吸收效率、氮肥偏生产力、氮肥农学效率 ...
