黑河地区为高纬寒地,在北纬50℃左右,气候寒冷,年平均气温在-1℃左右,≥10℃的活动积温1900～2300℃之间,水稻的生育期仅105～120天,处于我省农业区划的第四、五、六积温带,这里常被人们认为是种稻禁区。如能在种稻禁区实现水稻高产,是一项十分有意义的科研课题。近几年。经过我们探索,挖掘出高纬寒地水稻高产之潜力,初步研究了亩产400公斤高产栽培技术模式,这一模式已在大面积生产条件下示范应用。这不仅在高纬寒地种稻史上是个突破,而且
The Heihe region is characterized by high latitudes and cold temperatures of about 50 ° C at north latitudes with cold climate and an annual average temperature of -1 ° C. The active accumulated temperature of ≥10 ° C is between 1900 and 2300 ° C. The growth period of rice is only 105-120 days. The fourth, fifth, and sixth temperate zone of agricultural zoning is often regarded as a kind of restricted rice-planting area here. It is a very significant research project to realize the high yield of rice in the forbidden area. recent years. After we explored and tapped the potential of high-yielding paddy at high latitudes, the high-yielding cultivation technique model of 400 kg per mu was initially studied. This model has been demonstrated and applied under large-scale production conditions. This is not only a breakthrough in the history of high-latitude rice cultivation, but also
