我省西部地区光热资源丰富,无霜期长,耕地面积大,具有进一步提高玉米单产及总产的巨大潜力。但这一地区降水较少,且降水分布不均,有效性差,加之土壤贫瘠,农田投入能量少,主栽品种的选择、搭配及种植密度不合理,已成为玉米高产的主要限制因素。因此,抓好以下几项是提高本区玉米单产及总产的当务之急。一、狠抓以防旱抗旱为主的综合增产措施 1.深松改土,狠抓蓄水。深松不
The western region of our province is rich in light and heat resources, has a long frost-free period and a large area of arable land, and has the great potential to further increase corn yield and total output. However, the precipitation in this region is less, and the uneven distribution of rainfall and poor efficiency, coupled with the poor soil, less energy input into farmland, the selection and collocation of main cultivars and irrational planting density have become the main limiting factors for high yield of maize. Therefore, a good grasp of the following is to improve the area of corn yield and the top priority. First, pay close attention to drought and drought-based comprehensive stimulation measures 1. Subsoil soil, pay close attention to water. Deep loose no
