我国黑龙江省大部分地区属于高纬度寒冷地带。从北纬46°到北纬52°32′,冬季采暖期长达5～6个月,年最低温度在零下30多度;并且,高纬度地区冬天的日照时间短,太阳能资源较差。因此,这一地区的太阳能温室利用时间很短。为了延长高纬度地区太阳能温室作物种植时间,必须对温室辅以加热措施,但这样又增加成本,带来管理上的不便。如何采用廉价实用的辅助措
Most parts of China’s Heilongjiang Province belong to the high latitudes of the cold zone. From 46 ° north latitude to 52 ° 32’orth latitude, the heating period in winter is as long as 5 to 6 months, and the annual minimum temperature is below minus 30 degrees. In addition, the winter sunshine time is short and the solar energy resources are poor at high latitudes. Therefore, the solar greenhouse in this area is short-lived. In order to prolong the planting time of solar greenhouse in the high latitudes, the greenhouse must be supplemented with heating measures, but this adds cost and brings inconvenient management. How to adopt cheap and practical auxiliary measures
