The Study of Influence of Straw Mulch Amount to Soil Moisture Evaporation in Farmland
, 2008 为研究秸秆量与夏玉米农田保墒效果之间关系,【方法】结合小区试验和微型蒸发皿定量观测,研究了0、0.6、0.9、1.2 kg/m24种不同秸秆覆盖量对农田土面蒸发的影响规律。【结果】试验表明在无种植情况下,秸秆覆盖大于0.6 kg/m2时,能明显影响和保持0￣50 cm土层的土壤含水量。秸秆覆盖量大于0.9 kg/m2时,保墒效果不再明显增加。结合干旱小区玉米试验发现,秸秆覆盖量在0.6￣0.9kg/m2范围时,玉米增产效果明显。【结论】秸秆覆盖量为0.6￣0.9 kg/m2范围时 ...

Effects of Nitrogen on the Stomatal Characteristics of Canopy Leaves of Summer Maize(Zea mays L.)
, 2008 盆栽条件下研究不同施氮水平[0、0.15和0.30 g(N)·kg~(-1)(土)]对不同株型夏玉米冠层叶片气孔特性影响的结果表明,施氮后叶片气孔密度显著下降,但增加施氮量的气孔密度有所增大;与不施氮的相比,施氮的气孔长度、宽度和面积均下降。不同株型品种的气孔密度、气孔的长度、宽度和面积均以紧凑型‘陕单902’显著高于其他株型品种。不同施氮水平下不同叶层叶的气孔密度均表现为上层大于中下层,而气孔的长度 ...

Study on Summer Corn Canopy Interception under Sprinkler Irrigation
, 2008 以夏玉米为研究对象,采用水量平衡法对玉米各生育期在喷灌条件下的水量分布进行了试验和测定,计算了玉米各生育期的冠层截留量。试验结果表明:喷灌初始阶段,玉米冠层截留量随喷灌水量的增加而迅速增加,此后逐渐减缓直至达到最大冠层截留量。种植密度不同,玉米冠层截留量也不同。正常种植密度条件下,从拔节期到灌浆成熟期,冠层截留量随株高和叶面积指数的增大而线性增大,玉米拔节期到灌浆期冠层截留量在0.8~2.9mm之间变化 ...
