杂交玉米新品种毕单15号不同种植方式研究

目的]探讨适应杂交玉米新品种毕单15号的最佳种植方式。方法]通过对杂交玉米新品种毕单15号进行5种不同种植方式的对比试验。结果]结果表明:种植方式不同,玉米的产量、果穗性状、植株性状、根系分布范围和数量、叶面积大小和保绿期等不同;玉米实行宽窄行双行单株错位定向移植,保证了玉米沿着最佳的生物学轨道生长发育,比其他几种移栽方式和直播增产显著。结论]该研究为确定杂交玉米新品种毕单15号的最佳种植方式提供了依据。

Studies on Different Planting Patterns of New Hybrid Maize Variety-Bidan 15

Objective] The aim of the research was to discuss the optimum planting pattern for new hybrid maize variety—Bidan 15.Method] Comparison experiments with 5 planting patterns were conducted on new hybrid maize variety—Bidan 15.Result] The different planting patterns affected the yield,ear characteristics,plant characteristics,root distribution range and quantity, leaf area and keeping green stage in maize variously.Directional transplantation with individual plant misplacement planting between the wide and narrow rows could ensure that the growth of maize was along the best biological track,whose yield-increasing effect was more significant than other kinds of transplant patterns and direct seeding pattern.Conclusion] The research provided basis for confirming the optimum planting pattern for new hybrid maize variety—Bidan 15.
