不同种植密度及深松深度对玉米产量的影响

Effects of Different Planting Density and Subsoiling Depth on Maize Yield

在控制等量投入的情况下,以玉米品种良玉99和东科909为试材,设置玉米不同种植密度、不同深松深度等6种田间种植模式试验,研究种植密度、深松深度对春玉米产量的影响。并基于试验结果作出描述统计与回归分析,总结出不同密植条件与深松深度对玉米产量的影响程度。结果表明,在一定范围内,种植密度增加和增加深松深度会显著加增春玉米产量。因此,合理密植和适度深松两者有机结合可有效提高玉米产量。

Under the condition of controlling the same amount of input,6 kinds of interfield planting model experiments were set with different planting density and different subsoving depth of maize,including Liangyu 99 and Dongke 909,to study the effects of planting density and subsoving depth on spring maize yield.Based on the experimental results,descriptive statistics and regression analysis were made to summarize the influence degree of different dense planting conditions and subcropping depth on maize yield.The results showed that the yield of spring maize was significantly increased by increasing planting density and submerging depth within a certain range.Therefore,the organic combination of reasonable dense planting and moderate subcropping can effectively increase the yield of maize.
