聊城地区聊棉15号密度与穴株数变化对产量的影响

Effect of Density and Seedling Per Hole of Liaomian 15 on Yield in Liaocheng

为了聊棉15号精量播种提供数据支撑。通过裂区设计在山东省聊城市进行了田间试验,比较和分析密度(30000、45000和60000株/公顷)与每穴留苗株数(1穴2株、1穴1株、1株和2株相间留苗)处理对聊棉15号生育和产量的影响。结果表明,密度处理对产量的影响有显著差异,每穴留苗株数处理对产量差异没有显著性。聊棉15号精量(1穴播3~4粒)播种在山东聊城地区生产上是可行的,可作为一项轻简化栽培措施进行示范推广。

In order to provide data support for precision sowing of Liaomian 15. A field experiment was conducted in Shandong Liaocheng by split-plot design to compare and analyze the effects of density(30,000, 45,000 and 60,000 plants/ha) and the number of seedlings per hole(2 plants in 1 hole, 1 plant in 1 hole, 1 plant and 2 plants in 1 hole)on the growth and yield of Liaomian 15. The results showed that the effects of density treatments on yield were significantly different, and the treatments with the number of seedlings per hole had no significant difference in yield.The precision sowing(3 to 4 seeds per hole) of Liaomian 15 is feasible in production and can be used as a light and simplified cultivation measure for demonstration and popularization in Shandong Liaocheng.
