黑龙江省冬小麦气候区划研究

Division of winter wheat planting area based on climate in Heilongjiang Province

  • 摘要: 根据近年来黑龙江省各地冬小麦试种的田间试验及生产调查,结合该省气候历史资料分析得出影响冬小麦安全越冬、返青的5个农业气象指标,即冬季严寒、积雪深度、土壤水分、返青期气温变化及风速大小、春季冻融交替的倒春寒指标,由此计算出的气候综合指标值为主,辅以限制性指标进行修正,将该省划分为3个冬小麦气候区,即冬小麦可能种植区、冬小麦风险较大气候区、冬小麦不宜种植气候区,并提出发展该省冬小麦生产的建议。

     

    Abstract: According to the field experiments, production surveys, and the climate data of Heilongjiang Province in the past few years, five agricultural meteorological indexes including the winter cold, depth of snow accumulation, water content in the soil, temperature and wind speed in the turn green period, spring cold are put farward, which affects the safety of winter wheat during wintertime. These five indexes for the main index and other indexes for amending index, three winter wheat bands in Heilongjiang Province are divided including growing band, risk band and undaptable band. The production suggestions to develop the winter wheat are provided also in Heilongjiang Province.
