冬季条件下,如何才能提高温室内的温度,有效地预防冷害、冻害的发生,是蔬菜安全生产和获取高产最为关键的技术措施,低温,特别是低夜温是蔬菜温室生产最不安全的因素,是造成冷害、冻害,影响蔬菜生产发育的主要制约因素。那么如何增强作物的抗寒、抗冻性能,提高温室的温度,保持适宜的昼夜温差,就成为温室安全生产获取高产高效的最基本条件。本文针对以上这些情况作了多年的探索与实践,提出一些比较合理的解决措施。
Under winter conditions, how to raise the temperature in the greenhouse and prevent cold damage and frost damage effectively are the most important technical measures for safe production and high yield of vegetables. Low temperature, especially low night temperature is the most unsafe factor in vegetable greenhouse production , Is caused by cold damage, frost damage, affecting vegetable production and development of the main constraints. How to enhance the cold resistance and frost resistance of crops, raise the temperature of greenhouses and maintain the appropriate temperature difference between day and night become the most basic condition for obtaining high yield and high efficiency in greenhouse safe production. This article has made many years of exploration and practice for these situations and put forward some reasonable solutions.
