玉米是我国主要的粮食作物之一，随着我国经济水平的不断提升，人们的日常饮食更加注重膳食纤维的摄入，因而对玉米的需求量也与日俱增。对于提高玉米产量已然成为人们研究与关注的重点内容，本文就针对密度对玉米产量及主要农艺性状的影响进行分析。本次研究是以富民985、泽玉501、泽玉8911、翔玉211、翔玉198、登海618、MC278、天和2号为种植材料，以品种为主区，以种植密度60000株/hm2、70000株/hm2、80000株/hm2为副区进行裂区实验，对于8个不同品种在3个不同密度下其主要农艺性状以及产量的差异性进行研究，除了种植密度之外，像行宽、行长、区域面积等其他条件都保证一致。采取相同的管理方式实施管理，确保同一种玉米在除了种植密度不同之外的条件下，其他因素都相同。结果表明：在合适的密度下翔玉211、翔玉198、登海618产量相对较高，而综合一系列因素分析富民985、登海618两个品种则呈现低密度且高产的趋势。经试验数据得出产量其中第一位的是翔玉211在80000株/hm2处理下的产量，其次是富民985在70000株/hm2处理下的产量，第三位的是登海618在80000株/hm2处理下的产量，最后一位的是在登海618在70000株/hm2处理下的产量，试验结果表明，不同品种的玉米，在不同密度的种植下玉米的产量都是不同的，品种密度互作影响产量具有极显著差异，高密度玉米品种，诸如A4、A6、A5虽然在高密度的情况下产量高但是成本也较高，在选种种植时应倾向于低密度成本而高产量收入的A1M7、A5M7等组合品种。
英文摘要:
Corn is one of the main food crops in China. With the continuous improvement of China\&\#39\;s economic level, people pay more attention to dietary fiber intake in their daily diet, so the demand for corn is also increasing day by day. In this paper, the effects of density on Maize Yield and main agronomic traits were analyzed. In this study, Fumin 985, Zeyu 501, Zeyu 8911, Xiangyu 211, Xiangyu 198, Denghai 618, MC278, Tian 2 were used as planting materials. The main agronomic characteristics of eight varieties under three different densities were studied by split plot experiment with planting density of 60,000 plants/hm2, 70,000 plants/hm2 and 80,000 plants/hm2 as sub-areas. In addition to planting density, other conditions such as row width, row length, area and so on are guaranteed to be consistent. The same management method is adopted to ensure that the other factors of the same maize are the same except for the different planting densities. The results showed that the yields of Xiangyu 211, Xiangyu 198 and Denghai 618 were relatively high under suitable densities, while Fumin 985 and Denghai 618 showed a trend of low densities and high yields by comprehensive analysis of a series of factors. According to the test data, the yield of Xiangyu 211 was the first under the treatment of 80 000 plants/hm2, Fumin 985 under the treatment of 70 000 plants/hm2, Denghai 618 under the treatment of 80 000 plants/hm2 and Denghai 618 under the treatment of 70 000 plants/hm2. The test results showed that No. The yield of the same variety of maize is different under different planting densities. The interaction of variety densities has a significant difference in yield. High density maize varieties, such as A4, A6 and A5, have high yield but high cost under high planting densities. They should be inclined to low density cost and high yield when selecting planting varieties. Income of A1M7, A5M7 and other combinations.
