持续低温天气下设施口感型番茄管理技术

摘要：设施可局部范围改善或创造出适宜植物生长的环境条件，在一定程度上可有效控制和减轻灾害天气对作物的不良影响，然而，极端灾害天气仍会对设施蔬菜产生危害。为减少冬季低温持续时间长等极端天气对设施蔬菜造成的经济损失，减轻其对蔬菜市场供应平衡的影响，分析了持续低温对设施口感番茄生产的影响，梳理了设施口感番茄生产中应对持续低温灾害天气的技术措施，如增光增蓄热、强保温减散热、应急增温保秧保果、严格把控棉被放揭、合理开关风口、科学水肥管理、保花保果促熟果、病虫害防控等，为未来更好地应对可能发生的类似灾害天气提供技术支撑，帮助广大生产主体及时止损、减损。

Management Technologies of Facility Taste-like Tomatoes under Sustained Low Temperature Weather

Abstract: Facility can locally improve or create suitable environment for crops growth, and can effectively control and reduce the adverse effects of disaster weather on crops at a certain extent. However, extreme disaster weather can still cause harm to facility vegetables. In order to reduce the economic losses caused by extreme weather conditions such as prolonged low temperatures in winter on facility vegetables and mitigate the impact on the supply balance of the vegetable market, the impact of sustained low temperature on the production of facility taste-like tomatoes was analyzed, and the response technical measures for sustained low temperature disasters in production of facility taste-like tomatoes were sorted out, such as increasing light and heat storage, increasing insulation to reduce heat dissipation, emergency temperature increase to protect seedlings and fruits, strict control of cotton quilts, reasonably opening and closing of air vents, scientific management of water and fertilizer, protection of flowers and fruits to promote ripening and prevention and control of diseases and insect pests, which could provide technical support for better coping with similar disaster weather in the future and help the majority of production entities prevent and reduce losses in time.
