不同容器对宁夏基质培夏秋茬黄瓜生长发育的影响

Effects of different containers on growth and development of summer cucumber under substrate culture in Ningxia

以黄瓜品种京丰298为试验材料,采用有盖苯板泡沫栽培箱、无盖苯板泡沫栽培箱、塑料栽培槽、栽培袋4种栽培方式,研究不同容器对其生长、光合特性和产量的影响。结果表明,定植40 d时,使用有盖苯板泡沫栽培箱栽培的黄瓜株高和总产量显著高于其他3个处理;不同容器不同时期黄瓜叶片净光合速率的日变化均呈现双峰曲线形;在黄瓜的整个生育期内,有盖苯板泡沫栽培箱内的基质温度变化更为稳定;不同容器处理黄瓜平均单瓜质量和果实横径无显著性差异,但瓜长和总产量存在显著差异;有盖苯板泡沫栽培箱在夏季更适于黄瓜基质栽培。

Taking the cucumber variety Jingfeng 298 as test material,we carried out benzene plate foam box,benzene plate foam box without lid,cultivation slot,cultivation bag as four different containers and investigated their effects on growth,photosynthesis and yield of cucumber under substrate culture. The results showed that,after transplanting for 40 days,the height and yield of cucumber cultivated in benzene plate foam box were significantly higher than the other 3 treatments. Diurnal variation of net photosynthetic rate of cucumber leaves in different growth periods cultivated in different containers showed a bimodal curve shape. In the whole growth period of cucumber,changes of the temperature inside benzene plate foam box were more stable than the other 3 treatments. Moreover,single fruit weight in average and fruit diameter cultivated in different containers showed no significant difference,but there were significant differences in fruit length and yield. In conclusion,the benzene plate foam box was suitable for cucumber production under substrate culture in summer.
