浅议北方地区冬季蔬菜温室温度的管理

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。

Analysis of the Temperature Management of Greenhouse Vegetables on the North Areas in Winter

It is the key techniques how to increase temperatures for effective preventions occurrence of chilling injury and frost in winter for safe vegetable production and high-yielding. Low temperature,especially low night-temperature is the most insecure factors and the main contrains of vegetable greenhouse production,growth and development,and is the cause of chilling injury and damage. How to increase crop cold and frost resistance,it is the most basic condition for safe vegetable production and high -yielding...
