摘 要: | 目的]探究不同播种期对薏苡生长及产量的影响,选出适宜播种期。方法]采用5个不同播种期、实行田间小区试验的方法。种植方式以窝行距60 cm×60 cm进行种植,每种种植期设3个小区,随机区组排列,小区面积80 m2。苗期以每穴4苗进行定苗。根据生长期进行两次追肥和除草,以及有关生长数据采集,测产验收。结果]种植期对薏苡产量和生长都有很大的影响。播种期晚,将导致无效分蘖增多,侧枝减少,穗粒数降低,空瘪率高,千粒重减小,大籽粒所占百分率逐渐降低,最终产量降低,质量差。结论]为了获得高产,播种期应选在清明节之前。

Abstract: | Objective] To explore effects of different sowing period on growth and yield of Coix lacryma-jobi and selecting suitable sowing dates.Method] Adopting 5 different sowing periods with field plot method,spacing 60 cm×60 cm,3 plots at each period,random arrangement,plot area 80 m2,4 seedlingd in each cave,2 times fertilizing and weeding.Result] Planting period has significant effect on the yield and growth of Coix lacryma-jobi.Sowing dates too late will increase ineffective tiller,decrease lateral branches,grain number,1000-grain weight,proportion of large grain,resulting in poor yield and quality.Conclusion] For acquiring high yield,sowing period should be arranged before Tomb Sweeping Day. |
