门东公社位于老唐河故道,集体耕地二万九千多亩,大部份是沙土地,每年要种春夏播甘薯八千多亩,约占粮食作物面积的一半。因此,甘薯生产的好坏,直接影响对国家的贡献、集体生产和群众生活,公社党委和广大贫下中农对甘薯生产都很重视。在无产阶级文化大革命的推动下,一九六八年我们学习了山东省甘薯“下蛋”的经验。当时,在栽培上,他们主要是早、种、浅、直、清五个字。经过几年实践,我们针对自己的具体情况,近两年来把直字改为躺字,收到了较好效果。五年来实践证明,甘薯“下蛋”,在我们公社,不论直播躺栽,都比栽秧甘薯增产,一般增产三、五成,有的成倍 Gate East commune is located in the old Tanghe River, the collective farmland of more than 2900 acres, most of the sandy land, every year to plant sweet spring eight thousand acres, accounting for about half of the area of ​​food crops.
