不同苗数对‘文薏2号’群体结构和经济性状的影响
|
摘要
研究不同苗数对‘文薏2号’群体结构和经济性状的影响,探索最佳留苗数。通过田间调查与室内考种相结合的方法,分别对群体结构指标和经济性状指标进行测定。结果表明:不同苗数对‘文薏2号’单株分蘖数、单株总分枝数、单株有效分枝数、单株有效穗数的影响差异显著,且随着苗数的增加呈下降的趋势;随着每塘留苗数的增加,‘文薏2号’单株总粒数、单株实粒数、单株粒重均有减小的趋势;6株/塘处理‘文薏2号’的成穗率为88.48%、千粒重为107.24 g、产量为5363.33 kg/hm2,表现优于其他处理。不同苗数对‘文薏2号’群体结构和经济性状有显著影响,6株/塘是最佳留苗数。
The authors studied the effect of seedling number on group structure and economic characteristics of‘Wen Yi No.2'to explore the optimum number of seedling. The indexes of group structure and economiccharacteristics were measured by the methods of field investigation and indoor weighing. The results showedthat the effect of seedling number on tiller number, branch number, effective branch number, effective paniclenumber per plant was significant, which decreased with the increase of seedling number; total grain number,filled grain number and grain weight per plant decreased with the increase of seedling number; the earbearingtiller percentage of‘Wen Yi No.2'was 88.48% when the seedling number was 6 plant/pond, and thethousand-grain weight was 107.24 g, the yield was 5363.33 kg/hm2, the performance was better than othertreatments. Different seedling numbers had significant effects on group structure and economic characteristicsof‘Wen Yi No.2', and 6 plant/pond was the best seedling number.
