对大棚黄瓜的生长、产量性状及气象条件的观测分析结果表明,定植后气温高、积温多有利于黄瓜叶片数增加、提高出叶速度,有利于最大叶片长度、宽度及叶面积的增加,也有利于植株高度的增长,但导致黄瓜营养生长偏旺,不利于黄瓜结果数和单果重的增加,最终致使黄瓜单产下降。在茬口允许的情况下,夏黄瓜播种、定植期应适当提早,此时气温相对较低,有利于黄瓜产量的提高,获得较好的经济效益。
The results of observational analysis on the growth, yield characteristics and meteorological conditions of greenhouse cucumbers showed that after the planting, the high temperature and accumulated temperature were beneficial to the increase of the number of cucumber leaves and the increase of the leafing speed, which was beneficial to the increase of the maximum leaf length, width and leaf area, Which is conducive to the growth of plant height, but lead to a more prosperous vegetative growth of cucumber, which is not conducive to the increase of the number of cucumber and fruit weight, eventually leading to the decrease of cucumber yield. Crops allowed in the circumstances, the summer cucumber planting, planting should be appropriate early, when the temperature is relatively low, is conducive to the cucumber yield increase, access to better economic benefits.
