不同设施环境下番茄和黄瓜幼苗生长特性和水分利用效率

Growth Characteristics and Water Use Efficiency of Tomato and Cucumber Seedlings in Different Facilities

为探究不同设施环境对蔬菜幼苗的影响,以日光温室和植物工厂条件下番茄和黄瓜穴盘育苗为试验材料,开展不同设施环境对番茄和黄瓜幼苗生长和水分利用效率的影响研究。试验表明,日光温室条件下番茄幼苗株高、茎粗、叶面积和耗水量均高于植物工厂处理,不同处理番茄幼苗地上干质量差异不明显。日光温室条件下黄瓜幼苗株高、茎粗、地上干质量和耗水量均高于植物工厂处理。与日光温室相比,植物工厂显著提高了番茄和黄瓜幼苗地下干质量、壮苗指数和水分利用效率。由此可见,植物工厂在实现高效节水的同时能够生产优质壮苗,建议在植物工厂条件下开展蔬菜育苗工作。

To explore the effect of different facility environments on vegetable seedlings,with tomato and cucumber plug seedlings in solar greenhouse and plant factory as experimental materials,the research on the growth and water use efficiency of tomato and cucumber seedlings in different facility environments was carried out.The experiment showed that the plant height,stem diameter,leaf area and water consumption of tomato seedlings in solar greenhouse were higher than those in plant factory.There was no significant difference in aboveground dry weight of tomato seedlings under different treatments.The plant height,stem diameter,aboveground dry weight and water consumption of cucumber seedlings in solar greenhouse were higher than those in plant factory.Compared with solar greenhouse,plant factory significantly increased the underground dry weight,strong seedling index and water use efficiency of tomato and cucumber seedlings.It can be seen that plant factory can produce high-quality and strong seedlings while achieving high efficiency and water saving.It is recommended to carry out vegetable seedling cultivation under plant factory conditions.
