夏秋期间，我国浙、赣、闽三省交界的低丘红壤稻区经常发生季节性干旱，致使水利设施不完善的稻田，早稻收割后无法及时移栽晚稻，或因移栽后无水灌溉造成少菜迟穗而减产，有些甚至只能改种低产的秋杂粮，严重影响了晚稻生产。因此，我们针对该地区晚稻移栽至分孽期存在的缺水 During the summer and autumn, seasonal droughts often occur in the hilly red soil rice areas at the junction of Zhejiang, Jiangxi and Fujian provinces, resulting in the inability of timely transplanting late rice after harvesting of paddy fields and early rice with inadequate water conservancy facilities, or less after the transplanting Afterwards, the production of vegetables is reduced, some of them can even be planted with low-yielding autumn crops, seriously affecting the production of late rice. Therefore, we aimed at the lack of water during the transplanting to subdivision of late rice in this area
