不同加温方式对番茄穴盘育苗的效应

The Study on Effect of Heating Methods on Tomato Seedling

分别采用空气加温、基质电热线加温、基质空气加温等三种方式对番茄穴盘育苗的效果进行了研究。试验结果表明,在白天温度18～25℃,夜晚温度14～18℃两段变温控制条件下,以基质空气加温方式穴盘育苗效果最好。穴盘底部进行空气加温的番茄幼苗开展度/株高、根/冠、综合壮苗指数分别比空气加温条件下高11.34%、10.53%、42.62%,比电热线加温条件下处理高14.60%、31.25%和182.18%。,成本也较空气加温要低,可以在生产中推广应用。

Zhu Weimin,Zhu Longying,Xu Tiwei Abstract Three kinds of heating methods were used in raising tomato seedlings,such as air heating,medium heating,air heating under the plot.The results showed that the best way was air heating under the plot.And the temperature should be18-25℃on day time and14-18℃at night.Compared with the first and second method,the expansion/height,root/plant,integrate index of seedling is higher by11.34%,10.53%,42.62%and by14.60%,31.25%,182.18%.
