本课题采取与生产相近的条件,通过对贵州地区广泛种植的具有较好耐瘠高产特性的玉米杂交品种,选取中低肥力土和高肥力土进行对比筛选,初步获得以下研究结果:1.供试品种中,遵义8号、农大108、黔单16、登海3号四个品种在高肥力和低肥力两种土壤环境中的表现比较好,适应能力强,适应范围广,是适合在肥力不均匀地块种植的优良品种。适宜在黔中地区推广。2.表现较好的品种前期植株地上地下部分长势都强于表现较差的品种
为探究不同施氮水平对马铃薯苗期抗旱性的影响。本研究以川芋117为研究对象,采用沙培控制试验,通过对早期施氮后苗期马铃薯在干旱胁迫处理下生长、光合特性及叶片质膜体系、
1986—1987年间,用LI-1600稳态气孔计测定大豆7个品种叶片蒸腾速率表明:大豆开花期叶片蒸腾速率高于结荚期。植株中上部节位叶片蒸腾速率较大。一日中蒸腾速率高峰值在14时,
