宽垅密植是利用边行优势,加大留苗数量的一种密植方法。一九七三年我队第四生产队科学实验小组进行了玉米宽垅密植试验,取得了良好结果。平均亩产高达1053.2斤,比对照(本地一般种法)增产40%,效果显著,值得进一步试验、示范推广。他们的做法是:一、保持一般行距,突出边行优势。在我们本地的栽培习惯,一般玉米行距为1.8尺,为了突出边行优势,他们把一条行距加宽到2.6尺,另一条行距则缩小为1尺,宽行距与窄行距相间排列(如图一),
Wide 垅 close planting is the use of edge advantages, increase the number of seedlings close planting method. In 1973, the fourth production team scientific experiment team of our team conducted a wide-bore corn planting experiment and achieved good results. The average yield per mu is as high as 1053.2 kg, which is 40% more than that of the control (local common method). The effect is remarkable and it is worth further testing and demonstration. Their approach is: First, to maintain the general line spacing, highlighting the edge of the line. In our local farming practices, the general maize spacing is 1.8 feet. To emphasize the advantages of the borderline, they widen one row spacing to 2.6 feet while the other row spacing is reduced to 1 foot. The wide and narrow row spacing are arranged alternately (as shown in Figure 1 ),
