新疆北疆单双粒播种模式对不同高油酸花生品种农艺性状及产量的影响

Effect of Single and Double Seed Sowing Pattern on Agronomic Characters and Yield of Peanut Va⁃rieties with Different High Oleic Acid in Northern Xinjiang

在北疆片区对生产上主栽的5个高油酸花生品种开展不同种植模式试验,比较单、双粒播种方式对高油酸花生出苗率、开花比、分枝数、株高、侧枝长、产量等的影响,探讨适宜的栽培方式,以期改进北疆地区高油酸花生生产技术,旨在为花生品种选育中选择多个优良目标性状指明方向,高质高效完成目标性状选定,加速育种进程。试验结果表明:无论采用单粒还是双粒播种模式,对高油酸花生开花比、主茎高、侧枝长、分枝数都有显著影响。单粒对结果枝、干重有显著差异,双粒对出苗率、单株结果数、鲜重有显著差异。因此,在品种选择中应注重延长开花期、调整株型,促进主茎发育、控制侧枝长、增加分枝数量等方面的合理调控,获得更高产量。

In the Northern Xinjiang region,the production of the main plant of 5 high lysate peanut varieties to carry out different planting mode tests,compared single,double-grain seeding method on the high lyetic acid peanut seed⁃ing rate,flowering ratio,branch number,plant height,side branches The influence of long,yield and so on,to explore suitable cultivation methods,with a view to improving the production technology of high lyetic acid peanuts in north⁃ern Xinjiang,aims to select a number of good target traits for peanut varieties selection and breeding direction,high quality and high efficiency to complete the selection of target traits,accelerate the breeding process.The experimen⁃tal results show that no matter whether single-grain or double-grain seeding mode is used,it has a significant effect on the flowering ratio of high lyic acid peanuts,the height of the main stem,the length of the side branches and the number of branches.There were significant differences between single grain and result branching and dry weight,and there were significant differences between double grain and seedling rate,single plant results and fresh weight.Therefore,in the selection of varieties should pay attention to extend the flowering period,adjust the strain type,pro⁃mote the development of the main stem,control the length of side branches,increase the number of branches and oth⁃er aspects of reasonable regulation,to obtain a higher yield.
