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、CO_2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。
The relationship between the length of cucumber fruit and the growth of fruit perimeter and the greenhouse climate in glass controlled greenhouse was studied. The results showed that the correlation coefficients between the effective accumulated temperature and the fruit length and the fruit perimeter were all above 0.9. The effective accumulated temperature of 14 ~ 21 ℃ and the effective accumulated temperature of 13 ~ 25 ℃ indicated that the growth of fruit length and fruit perimeter were the best. The strength, temperature difference and CO2 content are the key meteorological factors that affect the growth of cucumber fruit. The actual production can be based on the expected goals, the use of the relevant climate and ecological parameters, the rational allocation of energy use time, adjust the process of fruit development to achieve the appropriate listing, to reduce production costs and increase production.
