黑龙江省齐齐哈尔市位于松嫩平原地区，地域辽阔，地势平坦。全年有效积温在2200～2700℃，无霜期115～125天，是杂粮主产区。近年来随着水稻旱育稀植栽培技术的推广，水稻生产面积有所增加。但由于本地水源、积温不足，田块漏水严重，盐碱地面积大，限制了水稻面积的进一步扩
Qiqihar City in Heilongjiang Province is located in Songnen Plain, a vast territory, flat. Effective annual accumulated temperature 2200 ~ 2700 ℃, frost-free period 115 to 125 days, is the main producing areas of miscellaneous grains. In recent years, with the popularization of cultivation techniques of rice in dry and drought cultivation, rice production area has increased. However, due to local water sources, lack of accumulated temperature, severe field leakage, saline-alkali land area, limiting the further expansion of rice area
