| 摘 要： | 目的]研究播种量及行距对直播稻产量结构的影响。方法]以南粳9108为试验材料,通过对收集的种植试验结果资料分析,研究了播种量及行距对直播稻有效穗数、实粒数、千粒重、产量的影响。结果]播种量、行距对有效穗数、实粒数和千粒重的影响程度不同,与其数理关系表达也不同。结论]在现有栽培管理水平下,南粳9108在播种量105~120 kg/hm2、行距28 cm时有利于提高产量。

| Abstract: | Objective]To research the effects of seeding rate and row spacing on the yield structure of direct-seeding rice.Method]With Nan-jing 9108 as the test materials,collected data of planting test were analyzed,the effects of seeding rate and row spacing on the effective spikes, filled grains 1 000-grain weight and yield were researched.Result]Seeding rate and row spacing showed different degrees of impacts on effective spikes,filled grains 1 000-grain weight.And their expression of mathematical relations also varied.Conclusion]Under the current cultivation management level,105-120 kg/hm2seeding rate and 28 cm row spacing was helpful to enhance the yield of Nanjing 9108. |
