| 摘 要： | 本文讨论了半干旱地区坡面集雨不同补灌条件下,玉米一生干物质积累与其在各器官中分配的动态及其差异,结果表明,集雨补灌可加速玉米的生育进程,增加生育前中期营养器官和中后期雌穗的干物质积累量,并从灌浆期开始各器官中的干物质迅速向雌穗转移,使雌穗占单株总干重的比重不断增加;不补灌的处理前期干物质积累比补灌的要慢,根冠比大,在当地后期雨水充足的情况下,干物质积累快,但成熟推后,产量降低;不同补灌方式中以覆膜坐水和前中期补灌2次的效果最佳,特别是拔节期补灌增产效果最为明显.

| Abstract: | In this paper,the dynamics and differences of maize life long dry matter accumulation and distribution among organs in different drop irrigation conditions at semi-arid area are discussed.The results showed rainwater harvesting for supplemental irrigation accelerates maize's growth and development and increases dry matter accumulation of vegetative organs in earlier and middle periods and the staging dry matter accumulation in ear in latter period.Besides,it makes the dry matter of every organs transfer to ... |
