我县是江苏省花生重点产区之一,一般年份播种面积在8万亩左右,大部分种植在废黄河、盐河沿岸及涟西片沙碱土地区。土地瘠薄,施肥水平低,产量低而不稳。为了提高单产,增加结荚率,去年在成吉、双河等公社,选择不同品种、土质、施肥水平的田块,进行了施用钾肥的多点试验。试验结果表明,一般增产幅度为13.6—34.7％,平均增产28.24％,平均每亩增产78.47

The planting area in the general year is about 80,000 mu, most of which is planted in the areas of waste Yellow River, salt river and rift area.
