| 摘 要： | 为确定陕北风沙草滩区玉米种植的最佳密度，通过设置667 m 4 000、5 000、 {6 000 }、7 000、8 000和9 000株6个密度梯度，主要研究不同的种植密度，对陕北风沙滩区春玉米的农艺性状、产量以及产量构成因素的影响。结果表明，株高、穗位高、秃尖长随种植密度的增加，呈增加趋势；产量随种植密度的增加，表现出先上升后降低的趋势；密度在 {8 000 }株·667m-2,供试品种可获得高产,产量1 148.96 kg·667m-2,较其他处理分别增产31.3%、16.6%、8.4%、4.8%和5.7%。

| Abstract: | In order to determine the optimal planting density of maize in wind sand and grass shoal area of northern Shaanxi, six density gradients of 4 000, 5 000, 6 000, 7 000, 8 000 and 9 000 plants·667 m-2 were set to study the effects of different planting densities on the agronomic characters, yield and yield components of spring maize in the wind sand beach area of northern Shaanxi. The results showed that the plant height, spike height and bald tip length increased with the increase of planting density. The yield increased first and then decreased with the increase of planting density. At the density of 8 000 plants·667 m-2, high yield was obtained, the yield was 1 148.96 kg·667 m-2, and the yield was 31.3%, 16.6%, 8.4%, 4.8% and 5.7% higher than other treatments,respectively. |
