| 摘 要： | 以谷丰888为试验材料,在施氮水平80kg/hm2和基本苗120万～130万株/hm2下,覆草栽培、覆膜盖模式研究灌浆期谷子籽粒糖类累积的动态变化。结果表明,籽粒灌浆期(花后14d),在覆草栽培和覆膜条件下,可溶性总糖分别比对照下降了5%和17%;蔗糖分别比对照下降了22%和0.20%;淀粉分别比对照上升了6%和11%。表明在覆草和覆膜下谷子器官中可溶性总糖、蔗糖降解,快速积累淀粉,为最终实现较高的粒重和产量提供了基础数据。 |

| Abstract: | The experiment was carried out to study the effects of three(Flat planting,straw mulching,plastic filmmulching)at N 80 kg/hm~2 and planting density plants 120×10~4-130 X 10~4/hm~2 on sugar contents and starch accumulation in grains during grain filling of foxtail millet variety Gufeng88.The results showed that straw mulching and plastic film-mulching of the total soluble sugar,sucrose contents and starch accumulation varied with,was decreased by 5%,17%than that of CK,was decreased by 22%,0.20%than that of CK,was increased by 6%,11%than that of CK.The degradation of total soluble sugar and sucrose foxtail millet straw and plastic film-mulching and the abitity supplying and utilizing assimilate straw and plastic film-mulching were strong during grain filling stage. |
| Keywords: | farming modes straw mulching plastic film-mulching foxtail millet total soluble sugar sucrose starch |
