摘要
黄淮海地区是我国第二大玉米产区,繁杂的种植模式给机械化收获带来很大的困难。通过河南、天津、河北和江苏的9个试验点进行3种种植行距(550,600,650mm)在相同的种植密度下的玉米产量、收获损失、作业效率对比研究,结果表明:不同种植行距对产量的影响不大,600mm行距的产量比其他行距的产量略高,平均提高6.7%;600,650mm种植行距的机械化收获的落穗损失相差不大,约2.33%～2.6%;600,650mm种植行距的机械化收获的作业效率高些。整体考虑黄淮海地区现有收获机的适应行距,结合作物产量、收获损失和收获效率,并有助于推进玉米机械化水平的快速提高,黄淮海地区夏玉米采用600mm的种植行距。
Huanghuaihai Region is the second major corn producing areas in our country.However,the planting patterns are too many to bring great difficulty to achieve mechanized harvest.The comparative researches on maize yield,loss of losing corn in mechanized harvesting,operation efficiency in three distributing in Shandong,Henan,Tianjin,Hebei and Jiangsu provinces have been conducted in this paper.The results show that： the different planting row space affected yield indistinctively,theyield of 600mm row spaceis slightly higher than the others,the average increase is 6.7%;The loss difference of losing corn in mechanized harvesting between 600mm and 650mm planting spaces is not significant,the loss is about 2.33%~2.6%;600mm and 650mm planting row spaces of the mechanized harvesting have a high operation efficiency.In the whole,considering the row space in the existing harvesters in Huanghuaihai Region,further,in order to push the highest increase of maize mechanization,the 600mm planting row space in Huanghuaihai Region summer maize is adopted.
