摘要
目的研究不同播期和播量对中药材红花产量和品质的影响,为红花种植提供参考。方法以卫红花为材料,采用裂区试验设计,研究播期播量对其产量和品质的影响。结果随着播期的推迟,红花植株株高、茎粗、节间数、第一有效分枝高度、无效分枝数、单株有效果球数、小区籽粒产量、羟基黄色素A含量均减少,有效分枝数先升后降,顶果球直径和顶果球着粒数先降后升。在同一播期内随着播量的减少,红花植株株高、节间数、第一有效分枝高度、小区籽粒产量变小;茎粗、有效分枝数、无效分枝数、顶果球直径、顶果球着粒数、单株有效果球总数、羟基黄色素A含量增加。10月8日前后播种,以1.5~1.8×10^4万/667 m^2为好;10月24日~次年02月14日前后播种,均以2.2×10^4/667 m^2为好;结论播期为影响红花生长发育的主要因素之一,其次为播量。晚播红花应适当增加播量有利于红花高产。
Objective To study yield and quality in different sowing time and density lay a foundation for planting safflower.Methods With"Weihonghua"as experimental materials,influences of sowing time and density on yield and quality in safflower are studied using the split plot experiment design.Results Plant height,stem diameter,node number,the first available branches height,invalid branch numbers,fruits number per plant,grain yield per plot,hydroxysafflor yellow A decreased with the sowing date delaying.Available branches,seed weight per plant first rose then dropped.Diameter of top fruit,number of seed top fruit decreased firstly then increased.Plant height,node number,first available branches height,grain yield per plot decreased with the sowing density delaying.Stem diameter,available branches,invalid branch numbers,diameter of top fruit,number of seed top fruit,fruits number per plant,seed weight per plant,hydroxysafflor yellow A increased.Seed density is 1.5~1.8×10^4/667 m^2 at October 8.Seed density is 2.2×10^4/667 m^2 at October 24~February 14.Conclusion Growth and development of safflower is affected by sowing time,followed by sowing density.Adequately increased sowing density with postponement of planting time is beneficial to high fruit yield and quality.
