搞好品种积温区划,是实行科学管理,有计划地按照自然区域选育、试验、繁殖、推广农作物优良品种,实现良种质量标准化,发挥良种增产作用的一项重要措施。黑龙江省自1978年开始,经孙震哲等同志努力,在气象部门和有关单位的配合下,根据我省20多年的气象积温资料和品种的特性、生态条件,抓住积温这个在自然诸因素中的主导因素,将全省从南到北每隔200度积温划一条积温带,全省共划6条,即第一积温带2,700度以上,第二积温带2,500—2,700度,第三积温带2,300—
To do a good job of dividing the accumulated temperature is an important measure to implement scientific management and systematically select and breed fine varieties of crops in accordance with natural regions and achieve the standardization of the quality of the improved varieties and to increase the yield of the improved varieties. Heilongjiang Province, since 1978, by the efforts of Sun Zhenzhe and other comrades, with the cooperation of the meteorological department and the relevant units, according to the characteristics and ecological conditions of meteorological accumulated temperature data and varieties in our province for more than 20 years, Dominant factors, the province from south to north every 200 degrees plot a plot of temperature, the province plan a total of 6, namely the first accumulated temperature of 2,700 degrees above the second accumulated temperature of 2,500-2,700 degrees, the third accumulated temperature of 2,300 -
