我县地处胶东“屋脊”,全县98万亩耕地,山地丘岭占90％以上。30万亩花生多种植在山丘旱地上。山丘地土层浅,肥力低,水源缺乏,地面不平,不抗旱、不耐涝。加之花生生长季节降雨分布极度不匀,往往受到干旱的严重危协。花生出苗期的降雨量平均仅有22.6mm;幼苗期只有60mm;秋天花生饱果期的遇旱机率高,平均不到三年。因此,花生产量历史
My county is located in Jiaodong “roof”, the county 980000 acres of arable land, mountain hill ridge accounted for more than 90%. 30 million mu of peanuts planted in dry hills in the mountains. Hill soil shallow, low fertility, lack of water, uneven ground, no drought, intolerance waterlogging. Coupled with the extremely uneven distribution of rainfall during the growing season of peanuts, they are often severely endangered by drought. The average rainfall of peanut in the seedling stage was only 22.6mm; the seedling stage was only 60mm; the probability of drought in the peanut saturated fruit stage in autumn was high, averaging less than three years. Therefore, peanut production history
