【摘要】 对日光温室内的温、光条件及其对作物种植制度的影响进行了研究。结果表明:我国北方日光温室在覆盖棚膜生产期间的见光时数小于12h,在不进行人工增光、补光的条件下,不宜种植以果实为主要产品的长日照植物,只可以种植以营养体为主要产品的长日照植物和短日照植物及对光照时间反应不敏感的中间型植物;≥10℃的活动积温的显著增加,为日光温室内实现多茬次栽培提供了必要的条件;光照强度、温度在南北方向上和垂直方向上存在的差异,为日光温室内实行多种作物间作、套种、立体种植提供了有利的条件。结论:根据日光温室内的温光条件,通过合理的作物种植制度,可以实现对日光温室内时空资源的多维利用。更多还原

【Abstract】 The air temperature and light condition and its effects on crop planting system in solar greenhouses are studied. The results show that: because the light time is less than 12 h during the production period with plastic film, covering solar greenhouses in northpart of China, on condition that light are not increased or replenished manually, are not suitable to grow long-day crops that produce fruits as main production, but are suitable to grow long-day crops that supply nutritorium as main production, short-day crops and intermedium crops that are not sensitive to light time; the notable increasing of annual active accumulated temperature(≥10℃), provides necessary condition for multiple cropping in solar greenhouses; the distributing differences of light intensity and air temperature in the directions of north - south and uprightness supply favorable condition for intercropping, relay cropping and multistory cropping in solar greenhouses. Therefore, it is possible to realize poly-dimension utilization of space-time resources within solar greenhouses by adopting rational crop planting system.更多还原
