(一) 从总的水热条件来说,南昌是双季稻栽培的适宜地区。但是,南昌地区的秋旱较为明显,对双季晚稻的影响较大,如果再出现盛夏干旱,则伏旱与秋干相联,对二晚的生长发育极为不利。本文试图通过28年来的气象资料讨论南昌地区7—9月秋伏旱的出现情况,结合环流特征,探讨大旱年与特大旱年出现的前期预报特征,提出克服干旱的可能途径,以供有关部门商榷。

This paper attempts to discuss the emergence of autumn and drought in autumn from July to September in Nanchang through 28 years of meteorological data, and to discuss the characteristics of the previous forecast in the great dry years and extremely dry years combined with the circulation characteristics, and put forward the possible ways to overcome the drought for the relevant departments Discuss.
