摘要
对日光温室增温效果和作物复种热量潜力试验研究结果表明 ,日光温室比室外≥ 10℃年活动积温增加2 2 0 5 3℃ ,日光温室喜凉和喜温作物套作复种或喜凉作物接茬复种均可实现 1年四熟 ,喜温作物接茬复种可实现 1年三熟。日光温室采用育苗移栽其作物复种热量潜力更大。
The effect of increasing temperature and the heat potential of sequential cropping in solar greenhouse were studied. The results show that the annual active accumulated temperature in solar greenhouse is 2205.3℃ higher than that outside; four crops a year by interplanting cool-season crops with warm-season crops or by sequential planting cool-season crops, and three crops a year by sequential planting warm-season crops can be harvested in solar greenhouse. The heat potential of the sequential cropping will be more higher if growing and transplanting seedlings are used in solar greenhouse.
