| 摘 要： | 在山西冷凉区(年活动积温2 600℃)地膜覆盖条件下,对谷子不同基因型杂交种进行了对比试验。结果表明:不同品种之间的产量结果差异显著,张杂谷3号、张杂谷5号与张杂谷10号的分蘖成穗较高,产量处于较高水平;张杂谷5号的1个基本苗成穗3.82个,张杂谷3号出籽率达81%;分蘖成穗与收获指数具有一定的相关性;张杂谷5号、张杂谷10号水分利用效率(WUE)分别达11.72,11.77 kg(/mm.hm2),说明种植谷子杂交种不会引起土壤水分的亏缺。 |

| Abstract: | The comparitive test of different genotype hybrids millet under the condition of polythene mulch in cold area with annually accumulated temperature of 2 600 ℃ in Shanxi was done and the results showed that there were significant differences of total yield among millet varieties.The rate of fertile tillers of hybrid millet Zhang 3,hybrid millet Zhang 5 and hybrid millet Zhang 10 were the highest,as well as the better total yield.The average tiller of a basic seeding of hybrid millet Zhang 5 was 3.82,the seed ratio of hybrid millet Zhang 3 was as high as 81%,and there was certain relationship between the rate of fertile tillers and harvest index.The WUE of hybrid millet Zhang 5 and hybrid millet Zhang 10 were 11.72,11.77 kg/(mm·hm2) respectively.It proved that hybrids millet cultivation could never bring about the soil moisture shortage. |
