The Influence of Nitrogen Mixed with Phosphorus on Soil Water Content and Water Use Efficiency of Summer Maize

, 2009
随土壤剖面深度的增加,土壤含水量逐渐降低,上层土壤含水量变幅大于下层。在同一氮肥水平下,夏玉米各生长期内0~50 cm土层含水量呈施磷处理高于不施磷处理,50~110 cm土层则反之。苗期—拔节—灌浆—收获期0~110 cm土壤蓄水量呈升高—降低—升高趋势;苗期呈氮磷配施处理高于单施氮肥处理,其它生长期氮肥与磷肥水平为120 kg/hm2配施处理最高;表层50 cm土层蓄水量均呈现氮磷配施处理高于单施氮肥处理,50~110 cm土层则反之 ...

包膜氯化钾对土壤养分供应强度及玉米产量、品质的影响

Shuitu Baochi Xuebao
目的控释氯化钾可实现钾离子缓慢释放与作物吸收相同步，同时保证钾离子在土壤中的有效性，满足作物生育后期对钾素的需求，显著提高钾肥利用率。探究长期施用控释氯化钾及其掺混肥料对玉米产量及品质的影响，为实现玉米高质量生产提供技术支持。方法基于控释氯化钾应用于夏玉米(Zea mays L.，郑单958)的田间长期定位试验(始于2014年)，设不施钾肥(CK)、常量普通氯化钾(K)、常量聚氨酯包膜氯化钾(CRK1)、减钾量1/3聚氨酯包膜氯化钾(CRK2)、常量掺混氯化钾(BBF1)、减钾量1/3掺混氯化钾 ...

黄淮海平原麦玉两熟区粮食产量与化肥投入关系的研究

利用统计资料和通过农户调查与田间试验 ,对黄淮海平原藁城市粮食产量与化肥投入的关系进行了研究。结果表明 ,藁城市粮食生产还有很大的增产潜力 ,总体上粮食产量与化肥的投入仍然呈显著正相关关系 ,但是 ,目前实际生产中化肥施用量存在极其严重的不平衡和不合理现象 ,所以增施化肥已不再是增产的主要措施 ,而合理统筹、提高化肥的利用率至关重要 ,是节能增效的重要措施。在冬小麦 夏玉米一年两熟种植中 ,秸秆全量还田条件下 ,N、P以不同比例配合施用 ,表现出显著的产量差异 ;而且增施N、P肥 ...
