水泥种植槽深液流水培蔬菜生产线设计与应用

    THE DESIGN AND APPLICATION OF A HYDROPONIC PRODUCTION LINE FOR VEGETABLE WITH DEEP FLOW TROUGHS MADE OF CEMBNT AND BRICKS

    • 摘要: 本生产线由以水泥沙浆砌抹火砖构成种植槽为核心的种植系统和保护作用的遮雨防虫大棚两个部分组成。作物根系生长在槽内较深的循环流动营养液中,营养液的理化状况稳定,能供给作物根系足够的水分,养分和呼吸所需的氧。因而,适种作物广泛,产量高,秋植番茄每公顷产量120吨,生菜定植后30天每公顷产45多吨。具有投资少,建造易,经久耐用,管理方便等特点。珠江三角洲各地已有许多县市用以代替昂贵的进口生产线。面积达2万

       

      Abstract: The hydroponic production line for vegetables was composed of two mainparts:the plantation troughs made of cement and bricks and the plastic greenhousefor insect protection and rain sheltering.The vegetable roots growed in a deeprecycling nutrient solution.The nutrient solution in the plantation system was stableand can provide enough water,nutrients and oxygen for root growth and itsrespiration. So the production line would be suitable for many crops to have highyields.The yield of tomata grown in autumn was above 120t/hm2 and the yield oflettuce in 30 days of growth was above 45 t/hm2.The production line ischaracterized by its low investment,durability,easy construction and management.ithas been extended to many cities in the Pearl River Delta and the extension areawas up to 20 000 m2 in Guangdong Province.
