摘要： 为了探索适宜当地甜糯玉米高产栽培的优化组合，以‘迪糯278’为试验材料，研究施肥水平（A1为金正大缓控施肥525 kg/hm2，A2为NPK三元复合肥750 kg/hm2，追肥尿素375 kg/hm2，A3为二铵300 kg/hm2、尿素300 kg/hm2、牛粪肥15000 kg/hm2）、种植密度（B1为45000株/hm2，B2为49500株/hm2，B3为52500株/hm2）对其主要农艺性状及产量的影响。结果表明：根系重与土壤容重呈极显著负相关，与土壤孔隙度呈极显著正相关。施肥水平、种植密度各自处理间的叶面积差异达极显著水平。在种植密度一定的条件下，施肥处理对鲜穗重的影响依次为A1>A2>A3；在施肥水平一定的条件下，种植密度对鲜穗重的影响依次为B1>B2>B3。单穗重与株高、叶面积、穗长、茎粗呈极显著正相关。总产量与株高、单穗重呈显著正相关，与叶面积、穗长、茎粗呈极显著正相关，与穗位高、穗粗相关未达显著水平。对‘迪糯278’而言，种植密度49500株/hm2产量最高。施肥金正大缓控施肥525 kg/hm2效果最好，施肥NPK三元复合肥750 kg/hm2，追肥尿素375 kg/hm2效果次之，施肥二铵300 kg/hm2、尿素300 kg/hm2、牛粪肥15000 kg/hm2第三。处理组合对产量影响程度依次为A1B2、A2B2、A3B2、A1B1、A3B1、A2B1、A1B3、A3B3、A2B3。

Abstract: To explore optimum composition of high yielding cultivation for local sweet-waxy maize, the influence of fertilization and planting density on main agricultural characters and yield in‘Dinuo278’were researched. The results showed that: root weight and soil bulk density was highly significant negative correlation, and highly significant positive correlation with soil porosity. Differences in leaf area reached a significant level in respective fertilization and planting density treatments. Under certain conditions of the planting density, the affect of fertilization treatments on fresh ear weight were A1 > A2 > A3. Under certain conditions of the fertilization levels, the impact of planting density on fresh ear weight was B1 > B2 > B3. Single ear weight saw a significant positive correlation with plant height, leaf area, ear length and stem diameter. Total production was significantly positively correlated with plant height and single ear weight, highly significant positive correlation with leaf area, ear length, stem diameter and no significant level with ear height and ear diameter. For‘Dinuo278’, the highest yield was got when its planting density was 49500/hm2.
