列宁格勒农业物理研究所的科学家们试制成新的人造气候试验室。在该试验室里能够产生从赤道到北极的自然条件。电子指挥系统能促成酷热或严寒、暴雨或干燥风、漫长的极昼或极夜。室内的温度能够在—20℃～+40℃范围内上下波动。 该设施将便于加速农作物的新杂交品种的育成以及增强其在各种极复杂的气象条件下的抵抗力。在该人造气候室里,一年内可以培植三熟以上的粮食作物、蔬菜和花。粮食的成熟仅需要2个月。 Scientists at Leningrad Institute of Agricultural Physics have piloted a new artificial climate laboratory. In the lab, natural conditions from the equator to the north pole can be created. Electronic command system can cause hot or cold, heavy rain or dry wind, a long day or polar night. The indoor temperature can fluctuate within the range of -20 ℃ ~ + 40 ℃. The facility will facilitate accelerated breeding of new hybrid varieties of crops and increased resistance to various extremely complex weather conditions. In the artificial climate room, food crops, vegetables and flowers more than three crops can be cultivated in a year. Mature food only needs 2 months.
