| 摘 要： | 对西南山区春玉米采用起垄直播覆膜、起垄覆膜育苗打孔移栽、起垄直播覆膜再加苗期拱棚双增温3种增温措施,研究不同增温措施对春玉米生育期、叶面积指数、干物质积累与分配及产量的影响。试验结果表明,3种增温措施使春玉米的生育时期提前,缩短生育期17～19d,提高春玉米不同生育时期叶面积指数,增加"光合源",提高干物质积累及最终向子粒库的转运(收获指数),增产幅度分别达11.48%、9.85%和14.93%,提高经济效益分别达571元/hm2、164元/hm2和256元/hm2。综合以上试验结果,西南山区春玉米生产栽培中以起垄直播覆膜为宜。 |

| Abstract: | The study was conducted with spring maize in the Southwestern Mountainous Area to investigate effects of different increment temperature measures such as covering on ridges after seeding,covering on ridges then transplant cultivation,adding arch to cover on ridges after seeding,on leaf area index,distribution and accumulation of dry matter and yield.The results showed that the leaf area index,accumulation of dry matter and harvest index under the different increment temperature measures were higher than the... |
