多穗高梁在塔里木地区今年是第一年大面积种植。在栽培技术措施中,急待解决问题之一是留苗密度问题。为此,我们选择了具有代表性的中等肥力土壤进行了不同密度对比试验,处理共分四个:1）60×15厘米,亩留苗7,400株;2）60×20厘米,亩留苗5,500株;3）60×25厘米,亩留苗4,400株;4）60×30厘米,亩留苗3,700株。生长期中,灌水、中耕、追肥各三次,总施入硝酸铵每亩为40斤,过磷酸钙20斤,收获后的产量鉴定结果如表1。 Multi-spike sorghum in the Tarim area is the first year of large-scale planting. In cultivation techniques, one of the urgent problems to be solved is the problem of the density of seedlings. To this end, we selected a representative medium fertility soil for different density comparison test, the treatment is divided into four: 1) 60 × 15 cm, mule Miao 7,400; 2) 60 × 20 cm, Mulamiao 5,500 Strain; 3) 60 × 25 cm, 4,400 strains of Mula Miao; 4) 60 × 30 cm, 3,700 acres of Mula Miao. Growing period, irrigation, cultivating, top dressing three times, total application of ammonium nitrate per acre 40 kg, 20 kg of superphosphate, the yield after harvest identification results in Table 1.
