温光控制工程技术推进日光温室生产提质增效

Engineering Technology Development of Temperature and Lighting Control Promote Productivity of Chinese Solar GreenhouseLiu Wenke

  • 摘要: 我国设施园艺产业发展迅速,世界范围内设施面积遥遥领先,已发展成塑料大棚、日光温室、玻璃温室、连栋温室和植物工厂多元设施类型并存的格局。日光温室是我国独有的设施类型,具有低投入、易管理等优势,但也存在单产低、环控水平差、环境污染严重、高低温和弱光胁迫频发、无法周年生产等诸多缺陷,在现有条件下提质增效的潜力较小。设施温光条件及其耦合调控能力是决定日光温室栽培模式和优质高产稳产的核心要素,继而关系到周年生产和生态环境效益的高低,亟待提高。研发日光温室环境与栽培系统温光调控工程技术装备,提高冠层-根区生长要素调控能力,提升日光温室抵抗、削减光温逆境危害能力,对提高单产、实现周年生产和倍增产出效益是有潜力可挖的。目前,我国日光温室温光调控工程技术装备取得了许多进展,该文重点对日光温室温光调控技术装备发展进行了分析,提出了未来的发展方向。

     

    Abstract: In China,protected horticulture industry has developed rapidly in the past decades,ranking first worldwide and consisting of plastic-covered tunnel,Chinese solar greenhouse(CSG),multi-span greenhouse and plant factory.CSG is unique greenhouse form of China with advantages of low cost,easy management.However,CSG has disadvantages of low per unit yield,bad environmental control capacity,severe environmental pollution and frequently suffered to high & low aerial temperature stresses.Up to date,CSG can′t be used for year-round production.In fact,temperature and light inner CSG are two crucial environmental factors that determine cultivation patterns and its productivity as well as year-round production ability and environmental impacts.So,to develop temperature and lighting control technology and equipment is key way to improve the productivity for CSG.Currently,some promising technologies were put forward for temperature and lighting control in CSG.Some novel technology progresses were collected and highlighted.
