自控温室黄瓜果长及果周径增长与气象因子关系的研究

Relationships among the length,perimeter increasing of cucumber fruit and climatic factors in selfcontrolled greenhouse

摘要: 研究了玻璃自控温室荷兰黄瓜果实长度、果周径生长与温室气候条件的关系。结果表明，不同界限温度的有效积温与果实长度、果周径的相关系数均达0.9以上，用14～21℃有效积温和13～25℃有效积温表征果实长度与果周径增长最佳，光照强弱、温差大小、CO₂含量是影响黄瓜果实生长速度的关键气象因子。实际生产中可根据预期目标，运用有关气候生态参数，合理分配能源使用时间，调节果实发育进程，达到适期上市，实现降低生产成本和增产增收。

Abstract: Relationships among the length,perimeter increasing of Holland cucumber fruit and climatic environment factors in self-controlled greenhouse were analyzed.Climatic factors affecting fruit's length and perimeter increasing velocity were pointed out. To adjust and control the climatic environment in greenhouse properly could increase yield and decrease cost.
